Description




FIELD OF THE INVENTION




The present invention relates generally to a shape and envelope rendering systems. More particularly, the present invention relates to the field of marking devices, including cutting devices and templates.




BACKGROUND OF THE INVENTION




Devices for rendering marks upon materials such as paper, cardstock and photographs are generally well known. Such devices, including cutting devices, are typically configured for performing free-form marking or cutting. Many marking devices are also used in conjunction with a template for marking or cutting specific or predetermined shapes from a material. Cutting devices having an adjustable blade are also known and are typically used for cutting materials of varying thicknesses. Other cutting devices can include a swiveling blade which swivel or rotate about a longitudinal axis of the cutting device. Cutting devices typically are elongate members having housings which form a handle for grasping by a user during cutting. The housing usually connects at its lower end to the blade. The angular position of the cutting blade of the cutting device with respect to the material to be cut is typically determined by the user's hand.




Templates are also well known. Templates typically are flat sheets having first and second sides, and one or more openings are formed in a variety of different shapes. The cross-sectional shape, of the periphery of the template and the edges of the template at the openings, typically defines straight-cut edges extending perpendicularly from the first side to the second side. Templates are commonly made of semi-transparent, generally flexible material. Templates used to produce geometric or other shapes of varying sizes can also be configured as nested templates. Nested templates include a series of elongate, unconnected slots which form outlines of specific shapes. When using nested templates, the user is required to cut the portions of the material to be cut which extend between the ends of the slots in order to completely outline or cut out the desired shape.




Existing devices for rendering marks and existing templates have a number of drawbacks. Existing rendering or cutting devices are typically not securely orientated in regard to angle with respect to the material. As a result, the angular orientation of the device with respect to the material to be cut (e.g., the blade of a cutting device) is often inadvertently changed causing an error in the desired marking or cutting. Existing devices which do fix the angular orientation of the cutting device with respect to the material are typically configured for free-form cutting only and do not properly function in conjunction with templates. Other devices which fix the angular orientation of the cutting device with the material to be cut are large, expensive devices which are often difficult to operate and to transport.




Further, existing cutting devices are typically formed of non-transparent material which partially obstructs the user's view of the material to be cut. Also, many cutting devices utilize a bottom-load blade connection of the blade to the housing of the device. The bottom-load connection of the blade to the housing makes the blade susceptible to becoming dislodged from the housing during operation. Existing cutting devices also typically do not include blade depth indication which increases the likelihood of blade depth mis-adjustment. Existing cutting devices also typically do not accommodate spare blades or blade assemblies. Those cutting devices, which have a rotatable or swivelable blade, are not typically configured for use with a template. When not in operation, existing cutting devices often have exposed cutting blades which are susceptible to contact by the user.




Existing templates are not configured for effective operation with cutting devices, and in particular, with cutting devices wherein the housing and the blade assembly are maintained in a generally fixed orientation with respect to the template. The periphery and the edges at the openings of existing templates often cause existing rotatable or swiveling blade assemblies to bind which can result in mis-cuts. Also, existing nested templates produce incomplete shapes and require the user to undertake a secondary cutting or marking operation, typically without the aid of the template, to complete the cutting or marking of the desired shape.




Thus, there is a need for a device for rendering marks or cuts onto a material which maintains the marking assembly in substantially constant angular orientation with respect to the material to be cut and which is configured for use in either a free-form rendering mode or a template rendering mode. There is also a continuing need for a cutting device which is configured for single-hand operation and which can be adjusted without the use of tools. What is needed is a cutting device having a blade assembly which is not susceptible to separation from the lower portion of the housing and a cutting device which indicates the depth of the cutting blade. A cutting device configured to prevent contact by a person with the blade when the device is not in use is also needed. Further, there is a continuing need for a cutting device having many of these attributes which also accommodates spare blade assemblies and which enables the replacement of blades without the use of tools. Additionally, there is a need for a template which operates effectively with a rotatable or swiveling cutting blade of a cutting device. In addition, a template is needed which enables the continuous and uninterrupted cutting of shapes of varying sizes.

According to another aspect of the invention, a template is included for facilitating the rendering of shapes onto a material by a rendering device. The template includes a substantially flat sheet having first and second sides, a periphery and at least one opening extending from the first side to the second side. The first side of the sheet is configured for placement upon the material to be cut. The second side of the sheet is configured to contact the rendering device. The sheet is made of a semi-transparent tinted template material. The first side laterally extends at the periphery and at the one opening farther than the second side to define a chamfer at the periphery and at the one opening of the template.




According to still another aspect of the invention, an envelope cutting system having a surface comprises a cutting unit including a frame having a lower support surface, a blade adjustment assembly coupled to the frame, and a blade assembly coupled to the frame. The blade assembly is positioned at least partially within the frame such that a longitudinal axis of the blade assembly is substantially perpendicular to the lower support surface of the frame. The blade assembly includes a blade retainer and a blade connected to the retainer, the retainer having a rigid collar, and the blade assembly rotatable about the longitudinal axis. At least one template includes first and second substantially flat surfaces, a periphery and at least one edge defining at least one opening forming the shape of an unfolded envelope. The lower support surface of the frame is configured for contacting at least one of the first surface of the template and the material to be cut. The second surface of the template is configured for placement upon the material to be cut, and the rigid collar of the retainer is configured to operatively engage at least one of the periphery and the edge of the opening of the template, thereby enabling the blade to cut a shape in the cutting material which assimilates the shape of at least a portion of the at least one of the periphery and the edge.

34


and the upper surface


36


of the base


24


combine to provide an annular handle which is configured to be easily grasped by the user enabling the user to easily move the cutting unit


12


in any direction across a surface of the material to be cut or the template


14


. The base


24


is preferably an annular member. Alternatively, the base


24


can be formed in other shapes such as, for example, a rectangular shape, an oval shape, a U-shape, or other conventional shapes.




The housing


26


is a generally cylindrical body having first and second openings


38


and


40


. The housing


26


is preferably integrally connected to the arm


28


and coupled to the base


24


. The first and second openings


38


and


40


of the housing


26


are defined to interconnect and axially extend through the housing


26


along a longitudinal axis


42


. The housing


26


is removably connected to, and partially encloses, the blade assembly

through the first opening


38


. The housing


26


is also configured to prevent the blade assembly


22


from fully extending through the second opening


40


of the housing


26


. This feature prevents the inadvertent separation or dislocation of the blade assembly


22


from the lower end of the housing


26


during operation. The housing


26


is also configured to enable the blade assembly


22


to move axially in a plurality of different positions based upon the adjustment of the blade adjustment assembly


20

The arm


28


is a curved support structure. The arm


28


is also preferably integrally connected to the base


24


and to the housing


26


for supporting the housing


26


above the aperture


32


of the base


24


. The arm


28


is configured to fixedly secure the housing


26


along the axis


42


in a position substantially vertical to the lower surface


30


of the base


24


. This configuration ensures that the blade assembly


22


is continuously maintained by the housing


26


, and the frame


16


is maintained in position in a substantially vertical position with respect to the base


24


when the base


24


is placed on a substantially horizontal surface. When in use, the arm


28


fixedly secures the angular orientation of the housing


26


with respect to the material to be cut. The configuration of the frame


16


eliminates the need for the user of the cutting unit


12


to adjust the angular orientation of the housing


26


and the swivel blade assembly


22


during operation. In alternative embodiments, the arm


28


can be configured to support the housing


26


and the blade assembly


22


in a plurality of different angular orientations with respect to the base


24


.




In a preferred embodiment, the arm


28


is a generally hollow structure and further includes an arm cover


44


. The arm


28


, including the arm cover


44


, forms a spare blade assembly storage compartment


46


for receiving at least one spare blade assembly. The arm cover


44

is configured to pivot about the axis


42


to enable a user to releasably access the storage compartment


46


. The arm cover


44


is made of a lightweight durable substantially transparent material, preferably, a clear polycarbonate material. Alternatively, the arm cover


44


can be made of other materials such as, for example, other thermoplastic materials or glass.




The storage compartment


46


of the arm


28


is sized to hold at least one spare blade assembly. The semi-transparent material of the arm


28


readily enables the user to visually ascertain whether a replacement blade assembly is stored within the storage compartment


46


without having to reposition the arm cover


44


from the arm


28


or disassemble the cutting unit. Alternatively, the arm


28


can be formed in other shapes or configurations, and it can be formed out of two or more members extending from the base


24


. Additionally, the storage compartment can be located at other locations on the frame


16


, such as, for example, formed as part of the base


24


.




The protective cover


18


is a generally circular disk shape. The cover


18


is removably connected to the base


24


and covers the lower surface


30


of the base


24


including the aperture

22


installed in the frame


16


, such as a cap for the lower end of the housing


26


and the blade assembly


22


. In another alternative embodiment, the blade assembly


22


can be configured to be completely retractable within the housing


26


.




The blade assembly


22

38


of the housing


26


and extends along the axis


42


within the housing


26


such that the lower portion of the blade assembly


22


outwardly extends from the second opening


40


of the housing


26


.




The blade assembly


22


includes a blade retainer


50


and a cutting blade


52


. The blade retainer


50


is preferably a cylindrical body having an enlarged upper end


54


and a lower end formed having a diameter which is smaller than the diameter of the main portion of the retainer


50


. The lower end of the retainer


50


forms a collar


56


. The retainer

is sized to fit within the first opening


38


of the housing


26


, to extend through the interior of the housing


26


, and to partially and adjustably extend through the second hole


40


of the housing


26


. The retainer


50


is also sized to angularly rotate or swivel about the axis


42


during operation in either a clockwise or counter-clockwise direction. The swiveling or rotating feature of the blade assembly


22


with respect to the frame


16


enables the blade


52


to follow a profile or shape defined in one of the templates


14


. The swiveling blade


52


can follow the free-form movement of the user's hand across a surface without requiring the separate adjustment of the blade


52


by the user during operation. The retainer


90


is configured to adjustably and axially extend within the housing


26


in response to the adjustment of the blade adjustment assembly


20


. The retainer


50


is made of a lightweight durable inexpensive material, preferably a plastic. Alternatively, other materials can also be used such as, for example, wood or metal. In an alternative embodiment, the retainer


50


can be configured to retain more than one of the blades


52


or blades of varying sizes.




The upper end


54


of the retainer


50


is sized so as to prevent the retainer


50


from fully extending in an axial manner through the second opening


40


of the housing


26


. The upper end


54


also includes an upper bearing surface which is configured to removably and operatively contact the blade adjusting assembly


22


. This enables the retainer


50


to rotate or swivel with respect to the axis


42


and with respect to the blade adjustment assembly


20


, or to move axially along the axis


42


.




The collar


56


is configured to removably contact an edge of one of the templates


14


and is configured to facilitate the operation of the blade assembly


22


in conjunction with one of the templates


14


. Specifically, the collar


56


is configured to slide along and rotate as necessary with respect to an edge or the periphery of the template


14


, thereby enabling the blade


52


to conform to the shape defined in the template


14


.




The blade


52


is preferably a conventional single-edged blade which is also preferably press-fit to the lower end of the retainer


50


. The blade


52


downwardly extends from the lower end of the retainer


50

. The plunger


62


is made a durable lightweight material, preferably, a plastic. Alternatively, the plunger


62


can be made out of other materials, such as, for example, wood or metal.




The biasing device


64


is connected at one end to the knob


60


and at a second end to the plunger


62


. The biasing device


64


is preferably a helical spring. The biasing device


64


provides the adjustable downward force upon the lower end of the plunger


62


to continuously urge the blade assembly


22


downward and to resist upward movement of the blade assembly


22


during operation. The configuration of the cutting unit


12


advantageously eliminates the need for a user to axially orientate the cutting unit during operation.





FIG. 3

illustrates the cutting unit


12


in greater detail in a side view. Specifically, the substantially flat lower surface


30


of the base


24


and the operating mode indicating portion


70


of the knob


60


are illustrated. The lower surface


30


of the base


24


is also configured to place in tension the material to be cut in order to smooth out the material for efficient cutting. The operating mode indicating portion


70


is configured to reflect the operating mode of the blade assembly


22


(see FIG.


2


).





FIG. 4

illustrates the operating mode indicating portion


70


of the knob


60


in even greater detail. The operating mode indicating portion


70


includes a free-form operating range segment


78


and a template cutting operating range segment


80


. When the cutting unit


12


is operating in the free-form range, the upper end


66


of the knob


60


is positioned further away from the housing


26


, thereby exposing the free-form portion


78


of the operating mode indicating portion


70


of the knob


60


above the first opening


38


of the housing


26


. This indicates to the user that the cutting unit


12


is in a free-form operating mode. When in the free-form mode of operation, the upward extension of the knob


60


reduces the pressure applied from the knob


60


to the biasing device


64


by enabling the biasing device


64


to upwardly extend (see FIG.


2


). The decreased pressure on the biasing device


64


results in a corresponding decrease in the pressure applied from the biasing device


64


to the plunger


62


and to the blade assembly


22


. The reduced pressure exerted onto the blade assembly


22


correspondingly results in less pressure or force exerted by the blade


52


onto the material to be cut. The free-form operating range enables the blade


52


to more easily upwardly and axially deflect during operation. The reduced pressure exerted onto the blade assembly


22


results in more efficient and effective free-form movement and cutting of the blade assembly


22


during free-form operation.




When the user desires to operate the cutting unit


12


in the template cutting mode of operation, the user simply re-positions the upper end


66


of the knob


60


closer to the housing


26


, until the free-form operating range segment is disposed within the housing


26


and the template cutting operating range segment


80


is visible above the first opening


38


of the housing


26


. This repositioning of the upper end


66


increases the downward pressure exerted on the biasing device


64


which correspondingly results in an increase in the pressure exerted by the biasing device


64


onto the blade assembly


22


. The increased pressure exerted onto the blade assembly


22


results in an increase in the pressure or force of the blade


52


against the material to be cut. When operating in the template cutting mode of operation, the blade assembly


22


deflects upward


14


less easily than when in the free-form operating mode. The increased downward pressure applied to the blade assembly


22


during the template cutting mode of operation enables the collar


54


of the blade assembly


22


to effectively contact and operate with the edges of a template while maintaining an effective cutting force on the material to be cut. The blade assembly


22


retains the ability to swivel during operation in either the free-form or the template cutting operating modes. The pressure with which the blade


52


presses against the material to be cut is determined by the position of the upper end


66


of the knob


60


with respect to the housing


26


. Rotating or screwing the knob


60


down, gradually increases the pressure on the blade


52


and subsequently allows a thicker medium to be cut.




Referring to

FIG. 5

, the template


14


and the cutting mat


15


are illustrated in greater detail. The template


14


is a substantially flat sheet having first and second sides


84


and


86


(see FIGS.


5


and


6


), a periphery


88


and at least one opening


90


extending from the first side


84


to the second side


86


. The second side


86


of the template


14


is configured for placement upon the material to be cut. The first side


84


of the template


14


is configured to contact the cutting unit


12


. The template


14


is also configured to facilitate the cutting of shapes or the rendering of marks upon a material. The template


14


is made of a lightweight and durable material. Preferably, the template


14


is made of a flexible and semi-transparent tinted material. In a particularly preferred embodiment, the template


14


is made of a thermoplastic material including an edge glow substance. The edge glow substance disposal of the semi-transparent material of the template


14


is configured to redirect light passing through the template


14


to the periphery, or to the edge of the at least one opening, of the template


14


. The edge glow substance is a colorant, such as the colorant supplied by Clariant International, Ltd. The edge glow substance disposed within the material of the template


14


provides the periphery


88


and the edge of the openings


90


within the template


14


with a glowing appearance. The glowing appearance of the template


14


facilitates the placement of the cutting unit


12


onto the template


14


, enhances the user's ability to view the overall template positioning, and provides the template


14


with an aesthetically appealing appearance.




The edges of the periphery


88


of the template


14


can be formed into a variety of different shapes such as illustrated in FIG.


5


. The openings


90


each describe a complete shape, thereby eliminating the need for secondary cutting or operation. The openings


90


can also be formed in a variety of different shapes or families of shapes such as, for example, hearts, stars, geometric shapes and alphanumeric shapes. In a preferred embodiment, as shown in

FIG. 1

, the template


14


can include alphanumeric indicia


92


positioned at each opening


90


indicating of the size and/or the shape of each opening


90


. For example, the indicia


92


could include “3.50″×2.50″ OVAL″ or 3.0″ HEART”. Alternatively, the indicia could be a numerical value next to an opening indicating the size of the opening


90


.




Referring again to

FIG. 5

, the template


14


further includes gridlines


94


formed into the first surface of the template


14


. The gridlines


94


facilitate the alignment of the template


14


onto the material to be cut. The template


14


can also include binder ring openings


96


for receiving a ring of a binder (not shown). Alternatively, the openings


96


can be used in conjunction with a clamping system or for template orientation.




The mat


15


is a sheet configured for placement underneath the material to be cut. The mat is configured to support the material to be cut without impeding the operation of the cutting device and to protect the surface upon which the mat


15


and the material to be cut rests. In a preferred embodiment, the mat


15


is made of a material having short or tight nap. The mat


15


is preferably made of a firm, flexible and inexpensive materials, and preferably the mat


15


is made of a thermoplastic material.




Referring to

FIGS. 6 and 7

, the template


14


is illustrated in further detail. The template


14


is preferably formed with a chamfer


98


at the periphery


88


and at the edges of the openings


90


within the template


14


. The chamfer


98


is defined within the template


14


such that the first surface


84


, which contacts the cutting unit


12


, laterally and outwardly extends to a greater extent than the second surface which contacts the material to be cut. The chamfer


98


facilitates the operation of the template


14


with the cutting unit


12


by enabling the collar


56


of the blade assembly


22


to operatively engage the edge or periphery of the template


14


during operation. The chamfer


98


reduces the surface area in contact with the collar


56


of the blade assembly


22


of the cutting unit


12


, thereby reducing the susceptibility of the blade assembly


22


(see

FIG. 2

) to bind during operation. The chamfer


98


also enables the user to more easily reposition or move the cutting unit


12


, along the edge of one of the openings


90


(see

FIG. 5

) or the periphery


88


of the template


14


, thereby facilitating the rendering or cutting of shapes onto the material to be cut. The chamfer


98


shown in

FIG. 7

thus further prevents the blade


52


of the blade assembly


22


from contacting an edge, or the chamfer


98


of, the template


14


during use, thereby preserving the integrity of the edge, or the chamfer


98


of the template


14


.




Additionally, referring to

FIG. 5

, the corners of the template


14


are configured to enable the cutting unit


12


to continuously and efficiently travel around one or more of the corners during cutting operation. This feature greatly reduces the amount of alignment required by the user when attempting to create a corner having an edge substantially similar to the template periphery


88


.




The system described herein can also be used for cutting and forming a variety of types of envelopes and/or packages of various shapes and sizes.

FIG. 9

shows an example of an envelope template


100


with an opening


102


formed therein. The opening


102


corresponds to the shape of an envelope, shown as a shape or opening


99


in

FIG. 10

, before it is folded into a position such that it is capable of receiving materials. As in

FIG. 9

, the cutting unit


12


cuts the material along an edge


104


of the template


100


to form the unfolded envelope shape.




As shown in

FIG. 10

, a scoring plate


110


is used to make scores or impressions on the unfolded envelope


99


once it has been cut by the cutting unit


12


. In the embodiment shown in

FIG. 10

, the scoring plate


110


includes an opening


114


with an outer edge


116


which defines the area to be scored when the user desires to create fold lines in the unfolded envelope


99


. The user presses firmly using a stylist or other hardened tool against the outer edge


116


while the unfolded envelope


99


is aligned with the outer envelope edge


119


on the scoring plate


110


. The scoring plate


110


also includes a plurality of bonding slots


118


. The bonding slots


118


comprise additional openings through which the user may place glue or another adhesive directly onto the unfolded envelope


99


which is placed below the scoring plate


110


.




After the adhesive has been placed in the bonding slots


118


, the envelope


99


is fully assembled as follows: a first side panel


111


and a second side panel


113


of the envelope


99


are folded inwardly such that they are substantially in contact with a center portion


121


. The user then folds the lower panel


115


such that the adhesive that has been placed on the lower panel


115


comes into direct contact with the first and second side panels


111


and


113


. The adhesive then bonds to the first and second side panels


111


or


113


, forming a pocket in which the material may be placed. The upper panel


117


may then be folded atop the lower panel


115


.




A similar template


100


and scoring plate


110


may be used to make an envelope


99


having different shaped panels, as shown in

FIGS. 13 and 14

.




As shown in

FIGS. 11 and 12

, it is also possible to form another form of envelope


99


resulting in an increased thickness such that thicker materials may be placed inside the envelope


99


once fully formed. As shown in

FIG. 12

, the scoring plate


110


includes additional fold lines


119


which are to be scored by a user. These additional fold lines


119


result in intermediate panels


120


,


124


,


128


and


132


, adding additional thickness to the resulting envelope


99


. In this particular embodiment of the invention, no bonding material is applied to the envelope


99


. Instead, a joining slot


131


is cut into a lower panel


126


. In this embodiment of the invention, the assembly of the envelope


99


is as follows. The first and second side panels


130


and


134


are joined to each other via hooks


137


formed in each of the panels


130


and


134


. The lower panel


126


is then folded, and the upper panel


122


is folded such that it passes into the adjoining slot


131


on the lower panel


126


.




As shown in

FIGS. 11 and 13

, it is also possible to include a variety of other shapes


106


into the individual template


100


. These additional shapes


106


can be used either inside the envelope


99


as embossments or used to cut different edges into the unfolded envelope


99


.





FIGS. 15 and 16

show yet another embodiment of the invention in which additional intermediate regions


169


are formed adjacent the first and second side panels


162


and


166


. After the first and second side panels


162


and


166


are folded, the lower panel


164


is folded, followed by the upper panel


166


. A tab


161


formed within the upper panel


166


is then fed between a pair of tabs


165


forming the lower panel, securing the envelope


99


.





FIGS. 17

,


18


A and


18


B show still another embodiment of the invention in which a multi-sided box


179


is formed. After the individual fold lines


116


are embossed using the scoring plate


110


, a plurality of center portions


180


are formed and is surrounded by first through sixth tabs


190


,


192


,


177


,


194


,


196


and


198


on one side and seventh through twelfth tabs


191


,


193


,


195


,


197


,


199


and


201


on the other side. After glue or another adhesive is placed within the bonding slot


118


, the unfolded box is folded such that an end tab


182


is folded onto the adhesive that was placed through the bonding slot


118


, forming a tube. On one side of the center panels


180


, the first tab


190


is folded over the tube, and the second and third tabs


192


and


177


are folded on top of the first tab


190


. The fourth tab


194


is folded over the third tab


177


and hooked under the tip of the first tab


190


. The fifth and sixth tabs


196


and


198


are also consecutively folded and hooked under the tip of the first tab


190


. This procedure is repeated for the seventh through twelfth tabs


191


,


193


,


195


,


197


,


199


and


201


on the opposite side of the center panels


182


. A perspective view of the box


179


in the partially assembled position is shown in

FIG. 18



b.






As shown in

FIG. 17

, it is also possible to include a variety of other shapes, such as hexagons


101


, diamonds


103


, hearts


105


, ovals


107


and circles


109


, into the individual template


100


. These additional shapes can be used for a variety of purposes. For example, the hexagon


106


serves as a box inset which can be cut out and used to reinforce the bottom of the box


179


being created. The hexagon


106


is sized to fit snugly with the walls of the box when assembled and can be placed inside the assembled box


179


with or without adhesive.




As shown in

FIGS. 19 and 20

, it is also possible to have a single template


200


include multiple openings that are used for a variety of purposes. For example, a first opening


202


in the template


200


corresponds to a first memory pocket


246


. The first memory pocket is capable of containing a small photograph therein. The unassembled first memory pocket


246


comprises a center portion


233


surrounded by a first tab


230


, a second tab


232


, a third tab


234


, a fourth tab


236


, a fifth tab


238


and a sixth tab


240


. To assemble the first memory pocket


246


, the first tab


230


is folded atop the center portion


233


. The second and third tabs


232


and


234


are then consecutively folded on top of the first tab


230


. The fourth tab


236


is folded over the third tab


234


and hooked under the tip of the first tab


230


. The fifth and sixth tabs are sequentially folded down and also hooked under the first tab


230


. All of these folds occur along the fold lines


216


that are embossed onto the unfolded first memory pocket


246


. First and second star mats


402


and


404


are used to define and set the photograph to be displayed. In particular, the first star mat


402


is used to crop the photograph (not shown), while the second star mat


404


is used to create a backing for the cropped photograph. The cropped photograph is joined to the backing with adhesive or similar joining mechanisms before being placed inside the first in the first memory pocket


246


. These components may be bonded to the inside of the first memory pocket


246


or simply placed inside the first memory pocket without any bonding materials.




The second opening


204


in the template


200


allows the user to form a second memory pocket


215


. The unassembled second memory pocket


215


comprises a center portion


223


surrounded by a first tab


220


, a second tab


222


, a third tab


224


and a fourth tab


226


. The second memory pocket


215


is assembled as follows. The first tab


220


is folded on top of the center portion


223


. The second tab


222


is then folded on top of the first tab


220


. The third tab


224


is folded on top of the second tab


222


and hooked under the tip of the first tab


220


. The fourth tab


226


is then folded atop the third tab


224


and hooked under the tip of the first tab


220


. All of these folds occur along the fold lines


216


that are embossed onto the unfolded second memory pocket


215


. First and second square mats


406


and


408


are used to define and set the photograph to be displayed. In particular, the first square mat


406


is used to crop the photograph (not shown), while the second square mat


408


is used to create a backing for the cropped photograph. The cropped photograph is joined to the backing with adhesive or similar joining mechanisms before being placed inside the first in the first memory pocket


246


. These components may be bonded to the inside of the first memory pocket


246


or simply placed inside the first memory pocket without any bonding materials.




The envelope cutting system of the present invention may also be used in conjunction with an embossing system as described in U.S. patent application Ser. No. 10/036,843, filed on Dec. 21, 2001 and entitled “Embossing System” and incorporated herein by reference. One such embossing system


310


is generally shown in

FIGS. 21A-23

. The embossing system


310


includes an upper template


312


and a lower template


314


. As shown in

FIG. 21B

, a textured plate


316


may be positioned generally below the lower template


314


. The textured plate


316


may include a variety of textured surfaces that may include grooves, ridges, undulations, or other textures. Alternatively, the textured plate


316


may include no texture at all depending upon the user's specific needs. The upper template


312


, the lower template


314


and the textured plate


316


are al′ removably positioned on top of a base plate


318


.




The upper template


312


includes a plurality of upper template shapes


322


. The upper template shapes


322


may vary greatly and could also include, for example, lettering, numbering or other designs. The lower template


314


includes a plurality of lower template shapes


324


. The lower template shapes


324


may also vary but are substantially identical in both shape, size and position to the upper template shapes


322


on the upper template


312


. In other words, the lower template shape


324


at a particular position on the lower template


314


is substantially identical to the upper template shape


322


at the same position on the upper template


312


.




In one particular embodiment, the upper template shapes


322


, although identical to the corresponding lower template shapes


324


, are slightly larger than the corresponding lower template shapes


324


. The slight different in sizes between the upper template shapes


322


and the corresponding lower template shapes


324


permit a user to make an improved, more crisp embossment along the edge of the shape to be embossed. In one embodiment, each upper template shape is about 0.050 larger in cross-section than the corresponding lower template shape


324


.




The upper template


312


, the lower template


314


and the textured plate


316


are all sized to fit on top of the base plate


318


in a close fitting relationship. As shown in

FIG. 21B

, the base plate


318


, according to one embodiment, includes a small depression


330


which is sized such that the textured plate


316


and/or the upper template


322


and the lower template


324


fit therein.




According to a preferred embodiment, the upper template


312


and the lower template


314


matingly engage the base plate


318


. This engagement is accomplished through the use of removable alignment pegs


320


positioned on the base plate


318


and corresponding upper template holes


332


and lower template holes


334


, along with a plurality of base plate holes


356


located along the base plate


318


. The alignment pegs


320


and the base plate holes


356


are positioned along an outer edge


344


of the base plate


318


. It is also possible to have additional ones of the base plate holes


356


on the sides of the base plate


318


for storage purposes, as shown in FIG.


21


A.




For each one of the alignment pegs


320


, there is an upper template hole


332


and a lower template hole


334


located in an identical position on the upper template


312


and the lower template


314


, respectively. The upper template holes


332


and lower template holes


334


are sized to closely fit with the alignment pegs


320


on the base plate


318


. When the upper template holes


332


, the lower template holes


334


and the alignment pegs


20


are in a mating engagement, the upper template


312


and the lower template


314


are impeded from moving relative to the base plate


318


. This feature greatly aids the user in operating the embossing system


310


without the risk of inadvertent movement of the upper template


312


or the lower template


314


. Additionally, this arrangement permits the upper template


312


and the lower template


314


from being completely removed from the base plate


318


. This permits the user to use different types of templates on the same base plate


318


, while also allowing the user to change the textured plate


316


depending upon the particular user needs.




According to one embodiment, the individual alignment pegs


320


are removable such that the user is able to use larger pieces of paper or other oversized mediums without bending the medium when a medium


326


is disposed inside the embossing system


310


. This arrangement also permits the user of other templates of varying sizes which may or may not be provided with the embossing system


310


.




In one embodiment, the embossing system


310


includes a storage compartment


350


with a lid


352


. The storage compartment


350


and the lid


352


may be used to store a stylus


328


, other marking instruments and/or the alignment pegs


320


. A variety of types of locking mechanisms may be used to secure the lid


352


, enclosing the storage compartment


350


.




The overall size of the embossing system


310


may vary depending upon the particular user requirements. In one embodiment, the embossing system


310


will be of a size to correspond to standard 8 ½″ by 11″ paper. Alternatively, the embossing system


310


could be sized to better fit standard greeting cards or other paper items. The embossing system may include a plurality of feet


354


coupled to the underside of the base plate


318


. The feet


354


, which may be formed from rubber or other materials, prevent or impede the base plate


318


from sliding along the surface upon which the embossing system


310


is placed.




The upper template


312


and the lower template


314


may be formed from PET or biaxially oriented film or mylar and can be transparent and/or tinted. The upper template


312


may include a preprinted upper template grid


352


, and the lower template


314


may include a preprinted lower template grid


350


. The upper template grid


352


and the lower template grid


350


may be used for properly aligning the medium


326


. The embossing system


310


may also include a self-healing cutting mat (not shown). The thickness of the upper template


312


and the lower template


314


may vary depending upon the particular use.




In a preferred embodiment, the lower template


314


has a thickness of about 0.010-0.020 inches and is formed from an opaque, colored plastic material. In a most preferred embodiment, the lower template


314


has a thickness of about 0.010 inches. It has been observed that when the lower template


314


has a thickness of about 0.010 inches, the medium is less likely to be torn during the embossing process than when the lower template


314


has a greater thickness. In a most preferred embodiment, the upper template


312


has a greater thickness than the lower template, and it has been found that there is improved quality in the embossment when the upper template


312


and the lower template


314


have different thicknesses. In a preferred embodiment, the upper template has a thickness of about 0.015-0.020 inches, with a most preferred thickness of about 0.015 inches. Other thicknesses for the upper template


312


and the lower template


314


may be used, and it is also possible for the upper template


312


and the lower template


314


to be of substantially identical thicknesses.




The upper template


312


and the lower template


314


may be laser cut, water jet cut, die cut, or punched out of sheet material. In one particular embodiment, the base plate


318


is injection molded.




The embossing system


310


includes the stylus


328


or similar marking mechanism for embossing or scoring the medium


326


. A variety of types of marking mechanisms may be used. One exemplary form of marking device includes a ball bearing at one end thereof. One such device is currently marketed under the name EMPRESSOR™ Alternatively, a pencil or other drawing instrument could be used in place of the stylus


328


. The embossing system


310


can be used on a variety of the medium including without limitation paper, card stock, bond paper, thirty pound vellum, metal foil, and other such materials.




The operation of the embossing system


310


is generally as follows. When a user desires to emboss a particular material, the user first selects the proper textured plate


316


and locates the selected textured plate


316


within the depression


330


of the base plate


318


. The user selects the particular shape to be embossed on the material, and places the lower template


314


containing that shape atop the base plate


318


, aligning the lower template holes


334


with the alignment pegs


320


. The user then positions the medium


326


on top of the lower template


314


in such a position as to cover the particular shape to be scored. Once the medium


326


is in a proper position, the user locates the upper template


312


on top of the medium


326


and the lower template


314


, aligning the upper template holes


332


with the alignment pegs


320


. The user maneuvers the stylus


328


within the particular upper template shape


322


which is to be embossed on the material


326


. During this process, the user may maneuver the stylus


328


along only the outer edge of the upper template shape


322


, or may maneuver it throughout the region. When the user is done maneuvering or scoring the upper template shapes


322


, the user removes the upper template


312


. The material


326


then includes an embossment corresponding to the upper template shape


322


and the lower template shape


324


.




According to an alternate embodiment and as shown in

FIG. 22

, the upper template


312


and the lower template


314


can be a variety of shapes and may also only include the upper template holes


332


and the lower template holes


334


on an upper template margin


336


and a lower template margin


338


, respectively. Although the positioning of the individual upper template holes


332


and the lower template holes


334


can vary, the upper template holes


332


and the lower template holes


334


still operate to fix the position of the upper template


312


and lower template


314


so long as they mate with the alignment pegs


320


on the base plate


318


. In one embodiment, the upper template holes


332


and the lower template holes


34


are positioned to align with the standard European and/or American binder hole arrangements.




In still another embodiment and as shown in

FIG. 23

, the upper template


312


and the lower template


314


are joined together at a single margin


340


that includes margin alignment holes


342


. The single margin


340


provides the user the added benefit of keeping the upper template


312


and the lower template


314


together at all times, minimizing the risk of at least one of the upper template


312


or the lower template


314


being lost. In this particular, the upper template


312


and the lower template


314


are hingedly or flexedly connected to each other such that the medium


326


can be easily positioned and removed from the embossing system


310


.




In yet another embodiment, an integrated clamp (not shown) may be used to further clamp the individual components of the embossing system


310


in place. For example, the integrated clamp can be used as a ruler for measuring and alignment of the medium


326


or other items in the embossing system


310


. The clamp can be spring tensioned to hold the individual components securely in place.




The embossing system


310


may also include a storage lid (not shown) sized to fit on top of the upper and the lower templates


312


and


314


, the textured plate


316


and the base plate


318


, mating with the alignment pegs


320


to safely secure all of the components. Additionally, a small light (not shown) may be positioned inside the depression


330


. The light may be used to illuminate the material


326


being embossed, making it easier for the user to identify whether the material


326


has been embossed and, if so, the degree of embossment.
