A cutting table for cutting pieces of fabric. The table has a fabric supporting surface mounted on a frame. A cutter is manually movable along a linear cutting path that is substantially perpendicular to an edge guide. First and second light emitting devices emit respective first and second lights in a direction substantially parallel to the linear cutting path. A manually powered drive supports the first and second light emitting devices in a spaced apart relationship, and the drive is manually operable to move the light emitting devices through equal displacements in opposite directions substantially perpendicular to the linear cutting path. The light emitting devices are used to quickly align the fabric, so that it can be cut to a desired width.
Description




FIELD OF THE INVENTION




This invention relates generally to a cutting table and, more particularly, to a cutting table for cutting fabric goods, materials or stock.




BACKGROUND OF THE INVENTION




The cutting of fabric or material for the manufacture of bedding and furniture can be done by hand or by a fully automated machine. Both have their advantages and disadvantages. For example, fully automated machines are accurate, reliable and require minimal labor; however, fully automated machines are expensive and often cannot be sold in price sensitive markets. Further, fully automated machines require substantial selvage on the fabric in order to reliably automatically cut the fabric to size. Hence, the fabric is used less efficiently than if it were manually cut in a manufacturing process. Thus manual cutting often provides some benefits and efficiency with respect to material usage; however, it is difficult and time consuming for an operator to manipulate and cut larger fabric pieces such as those used in bedding. Therefore, known methods of manually cutting of the material are also expensive.




Consequently, there is a need for cutting table that facilitates a manual fabric cutting process, so that material of a desired size can be efficiently and quickly cut.




SUMMARY OF THE INVENTION




The present invention provides a cutting table that permits fabric to be easily and quickly manually aligned so that the fabric can be accurately cut with parallel edges. Such a cutting table provides a significant advantage in servicing those markets where fully automated machines are price prohibitive. The cutting table of the present invention also permits the fabric to be quickly and accurately manually aligned with an existing pattern in the material. Hence the cutting table has a further advantage of having more flexibility. The cutting table of the present invention also permits fabric with minimal selvage to be trimmed and used in production. Material with minimal selvage would otherwise be scrapped; and therefore, the cutting table of the present invention has a still further advantage of a more efficient use of the fabric.




According to the principles of the present invention and in accordance with the described embodiments, the invention provides a cutting table for cutting pieces of fabric. The table has a fabric supporting table surface mounted on a frame. A cutter is manually movable along a linear cutting path that is substantially perpendicular to an edge guide. First and second light emitting devices emit respective first and second lights in a direction substantially parallel to the linear cutting path. A manually powered drive supports the first and second light emitting devices in a spaced apart relationship, and the drive is manually operable to move the light emitting devices through equal displacements in opposite directions substantially perpendicular to the linear cutting path. The light emitting devices are used to quickly align the fabric, so that it can be cut to a desired width.




In one aspect of this invention, a carriage mounted on the frame supports the manually powered drive, and the carriage is manually movable in a direction substantially perpendicular to the cutting path. Further, the manually powered drive has first and second racks supporting the respective first and second light emitting devices. The first rack engages one side of a pinion and the second rack engaging an opposite side of the pinion. A handwheel is connected to the pinion, and rotation of the handwheel moves the racks through equal displacements in opposite directions.




In another embodiment of the invention, a method is provided for cutting a piece of fabric. First, the fabric is manually placed on a table surface to locate a first edge against an edge guide and a second, adjacent edge across a linear cutting path substantially perpendicular to the edge guide. First and second light emitting devices are moved to a location where respective first and second lights are substantially equidistant from a desired center line of the fabric. A cutter is then manually moved along the linear cutting path identified by the first light to cut a second edge of the fabric substantially perpendicular to the one edge. The fabric is manually moved on the table surface to locate a third edge, opposite the first edge, against the edge guide, and the second edge of the fabric in line with the second light. The cutter is again manually moved along the linear cutting path to cut a fourth edge of the fabric that is substantially parallel to the second edge. The distance between the second and fourth edges being substantially equal to the desired dimension, for example, width, of the fabric.











These and other objects and advantages of the present in will become more readily apparent during the following detailed description taken in conjunction with the drawings herein.

DETAILED DESCRIPTION OF THE INVENTION




Referring to

FIG. 1

, a fabric goods cutting table


20


has a frame


22


that includes four legs


23


with adjustable feet


25


for leveling the table


20


. The frame


22


is assembled from cut pieces of commercially available extruded aluminum. The cutting table


20


has a top


27


made from a suitable material, for example, plastic, metal, etc., and has a flat upper surface


24


for supporting flat goods or material


26


, for example, a piece of fabric that may be quilted. A trackway


28


is recessed into the top surface


24


and guides a cutter


30


. The cutter


30


is supported on the trackway


28


by linear bearings and thus, the cutter


30


is easily manually moved back and forth along the trackway


28


by an operator gripping the handle


32


. The cutter


30


has a powered cutting tool (not shown) the path of which along the trackway


28


defines a cutting path


29


of the cutter


30


.




Mounted near a rear side


34


of the cutting table


20


is a guide


36


. The guide


36


is formed by one side of right angle bar stock


37


. A perpendicular side


38


(

FIG. 2

) of the right angle bar stock


37


is attached to the table surface


24


by bonding, fasteners or other known means. A scale


40


is also attached to the table top


24


behind the guide


36


. The scale


40


has a zero value that intersects the cutting path


29


extending along the trackway


28


. The scale


40


can be adhered or bonded to the table surface


24


; however, attaching the scale


40


with fasteners permits adjustment of the scale


40


with respect to the cutting path


29


.




Referring to

FIG. 2

, a movable carriage


44


is mounted on the rear side


34


of the cutting table


20


. The movable carriage


44


is mounted on upper and lower crossrails


46


,


47


, respectively, extending across the rear side


34


of the table frame


22


. The crossrails


46


,


47


have respective grooves


48


that receive and guide the circumferential edges of rollers


50


. Handles


52


permit the carriage


44


to be moved linearly along the crossrails


46


,


47


over the width of the cutting table


20


. A particular location may be chosen by aligning an indicator line or pointer


54


on a finger


56


with a dimension marked on the scale


40


. A locking plate


58


(

FIG. 1

) is mounted to the carriage


44


immediately adjacent the upper crossrail


46


. The carriage


44


is locked at a desired location with respect to the crossrails


46


,


47


by tightening a screw (not shown) that extends through the locking plate


58


and against the upper crossrail


46


.




The carriage


44


is made from the same aluminum extrusions as the frame


22


and is generally T-shaped with a horizontal, rectangular top frame


60


that is rigidly connected to upper ends of a pair of generally vertical posts


61


. The top frame


60


has a pair of parallel upper and lower cross members


62


,


64


, respectively, that are tied together at their ends by a pair of opposed straps


66


. The top frame


60


has a length that is substantially coextensive with the rear side


34


of the cutting table


20


. Referring to

FIG. 3

, upper and lower racks


68


,


70


are mounted for sliding motion with respect to the upper and lower cross members


62


,


64


, respectively. End slider blocks


72


and intermediate slider blocks


74


are connected to the racks


68


,


70


and guide linear motion of the racks


68


,


70


relative to the respective cross members


62


,


64


. A pinion


76


is rotatably mounted in a gear box


78


(

FIG. 1

) that, in turn, is mounted to the lower cross member


64


. The pinion


76


is mechanically coupled within the gear box


78


to a manually operable hand wheel


80


. Thus, rotation of the hand wheel


80


directly rotates the pinion


76


which results in equal but opposite linear motions of the upper and lower racks


68


,


70


with respect to the respective upper and lower cross members


62


,


64


.




Referring to

FIG. 3

, a first laser mounting assembly


90


is connected to an outer end. of the lower rack


70


. A laser mounting bracket


92


and laser alignment bracket


94


are connected to the end slider block


72


. A laser


96


is mounted on the bracket


92


at an orientation such that it illuminates the table surface


24


with a line of light that is substantially perpendicular to the guide


36


and substantially parallel to the cutting path


29


of the cutter


30


. Such a laser


96


is commercially available as part no. 17405, Style #L7LL, from LaserLyte of Torrance, Calif. As shown in

FIG. 1

, a laser


98


is mounted on an end of the upper rack


68


. The laser


98


and its mounting is substantially identical to the laser


96


.




In use, referring to

FIG. 4A

, the handles


52


are used to linearly move the carriage


44


such that the indicator


54


aligns with a value on the scale


40


that is equal to the desired width of the fabric


26


, for example, 80 inches.




Since the indicator


54


is a center line indicator, the scale


40


is dimensioned in half-scale markings, that is, the 80 inch marking is 40 inches from the zero reference. The locking plate


58


is then secured to the upper crossrail


46


, thereby locking the carriage


44


at a position at which light beams


108


,


110


of respective lasers


96


,


98


are equidistant from the desired center line of the fabric.




Referring to

FIG. 4B

, the fabric


26


is placed on the top surface


24


of the cutting table


20


. The fabric


26


is normally rough cut to length such that it has substantially linear and parallel front and rear edges


100


,


102


, respectively. However, the fabric


26


has not been cut to width and to optimize the use of the fabric as well as the efficiency of subsequent sewing operations, it is desired that the selvage on the opposed first and second sides


104


,


106


, respectively, be cut off to provide side edges that are parallel and separated by a desired width.




To properly align the fabric on the surface


24


, the rear edge


102


is first aligned with the guide


36


, and the selvage edge


104


is located to the left of the cutting path


29


as viewed in FIG.


4


B. The lasers


96


,


98


are turned on, and they illuminate the upper surface of the fabric


26


with respective lines of light


108


,


110


. Next, the handwheel


80


is manually rotated, thereby causing the lasers


96


,


98


to move. The handwheel


80


is used to align the light beam


110


of the laser


98


with the zero scale value and the cutting path


29


of the cutter


30


. The fabric


26


is checked again to make sure that the selvage edge


104


is to the left of the light beam


108


.




While the laser


98


on the upper rack


68


was being moved to the left as viewed in

FIG. 4B

to the zero reference on the scale


40


by rotation of the handwheel


80


, the rack and pinion construction caused the lower rack


70


and laser


96


to be moved an equal distance to the right. Thus, when the light beam


110


is aligned with the cutting path


29


, the laser


96


is automatically positioned at a location such that the light beam


108


is separated from the light beam


110


by the desired width of the fabric


26


, that is, in the present example, the light beam


108


is 80 inches away from the light beam


110


.




At this point, a marking or indicia


112


is made on the fabric


26


near its front side


100


and in alignment with the laser light beam


110


. Thereafter, referring to

FIG. 4C

, weights


118


are placed over the fabric


26


to hold it in place. The cutter


30


is moved with its handle


32


along the trackway


28


, thereby cutting off the selvage edge


104


and providing a straight cut edge


114


that is substantially perpendicular to the fabric rear edge


102


. Thereafter, as shown in

FIG. 4D

, the weights


118


are removed; and the fabric


26


is rotated 180° until, as shown in

FIG. 4E

, the indicia


112


and cut edge


114


are aligned with the light beam


108


from the laser


96


. The weights


118


are again placed over the fabric


26


, and cutter


30


is again manually moved along the trackway


28


to cut off the selvage edge


106


. That operation provides another straight cut edge


116


that is separated from the first cut edge


114


by the desired width, that is, in this example, 80 inches. Further, the second cut edge


116


is parallel to the first cut edge


114


and perpendicular to the fabric ends


100


,


102


.




Referring to

FIG. 5A

, the process is again illustrated using a different size fabric


26




a


. Again, the carriage


44


is moved to a location where the indicator


54


aligns with a dimensional value of the scale


40


that is equal to the desired width of the fabric


26




a


. The carriage


44


is locked in position; and the handle


80


is rotated to move the lasers


96


,


98


in a direction such that the light beam


110


aligns with the zero reference of the scale


40


and the cutting path


29


of the cutter


30


. The fabric


26




a


is spread over the surface


24


, so that the rear edge


102




a


is aligned with the guide


36


and the selvage edge


104




a


is located to the left of light beam


110


as viewed in FIG.


5


A. Referring to

FIG. 5B

, the weights are placed on the fabric


26




a


; the cutter


30


is moved along the trackway


28


to cut off a selvage edge


104




a


and produce a first cut edge


114




a


. The weights


118


are then removed; and as shown in

FIG. 4C

, the fabric


26




a


is rotated 180° to move the cut edge


114




a


into alignment with the light beam


108


from the laser


96


. The cutter


30


is again moved along the trackway


28


to cut off the selvage edge


106




a


and produce a second cut edge


116




a


that is parallel to, and separated a desired distance or width from, the first cut edge


114




a.






Referring to

FIG. 6A

, the cutting table


20


can be used with a piece of fabric


26




b


having a pattern


120


, for example, a quilted pattern, image, etc., at its center. For the pattern to accurately have its desired centered orientation, the selvage edges


104




b


,


106




b


should be cut to be the same distance from the respective pattern sides


122


,


124


. The cutting table may be used in different ways depending on whether the distance from the pattern edges


122


,


124


to the respective fabric edges


104


,


106


should be simply equal or a specified dimension. If they are simply to be equal, then the following process can be used. First, the fabric


26




b


is spread on the surface


24


with its rear edge


102




b


located against the guide


36


and its selvage edge


104




b


extending to the left of the cutting path


29


as viewed in FIG.


6


A.




If the pattern width, that is, the distance between the pattern edges, is known, as described above, the carriage


44


is moved to a location at which the indicator


54


is aligned with a dimension on the scale


40


equaling the pattern width. At this point, the light beams


108


,


110


should align over the respective pattern edges


124


,


122


. As will be appreciated, the pattern width may not be exactly the size specified; and one or both of the light beams may not align with the pattern edges


122


,


124


. In this event, the handwheel


50


and carriage


44


should be adjusted until the lasers beams


108


,


110


do align with the respective pattern edges


124


,


122


; and the carriage


44


is then locked at that location. The above procedure of manipulating both the handwheel


80


and the location of the carriage


44


can also be used if the width of the pattern


120


is not known.




Referring to

FIG. 6B

, the weights


118


are placed over the fabric


26




b


; and the cutter


30


is moved along the trackway


28


to cut off the selvage edge


104




b


and provide a first cut edge


114




b


. Referring to

FIG. 6C

, the weights


118


are removed and the fabric


26




b


is rotated 180° to move the cut edge


114




b


into alignment with the light beam


108


. The weights


118


are again placed over the fabric


26




b


; and the cutter


30


is again moved along the trackway


28


to cut off the selvage edge


106




b


. That operation produces a second cut edge


116




b


that is parallel to the first cut edge


114




b


; and further, the cut edges


114




b


,


116




b


are a uniform distance from the respective pattern edges


122


,


124


.




In other applications, it may be desirable that the cut edges


114




b


,


116




b


be a specified distance from the respective pattern edges


122


,


124


. Referring to

FIG. 6A

, after the fabric


26




b


is spread on the surface


24


so that the rear edge


102




b


aligns with the guide


36


, the handwheel


80


is turned until the light beams


108


,


110


align with the respective pattern edges


124


,


122


. Then the carriage


44


is unlocked and moved until the light beam


110


is aligned with a dimension on the scale


40


that is equal to the specified distance between the cut edges and the respective pattern edges. The carriage


44


is again locked. The fabric


26




b


is then relocated on the surface


24


until the pattern edges


122


,


124


align with the respective light beams


110


,


108


and the rear edge


102




b


is located against the guide


36


. The above described process with respect to

FIGS. 6B-6D

is then repeated with the result that the cut edges


114




b


,


116




b


are the specified distance from the respective pattern edges


122


,


124


.




In the above description, the fabric


26




b


has a pattern


120


with opposed edges


122


,


124


that are used to align the laser lights


108


,


110


. As will be appreciated, the edges


122


,


124


function as alignment guides or elements; and alternatively, the pattern


120


may have other indicia functioning as alignment guides. The fabric cutting process is simplified and most efficient if the alignment guides are symmetrical with respect to the pattern center line or the cut fabric center line, if different. In such applications, the pattern


120


does not have to have parallel edges but could be circular or irregular in shape.




The cutting table


20


thus permits fabric to be easily and quickly manually aligned and accurately cut with parallel edges. The cutting table


20


as an advantage of being able to service those markets where fully automated machines are price prohibitive. The,cutting table


20


also permits fabric having a center pattern to be quickly manually aligned and cut to provide a uniform border with respect to the centered pattern. Further, the size of the border can be specified. Hence the cutting table


20


has a further advantage of having more flexibility. By being manually aligned and operated, the cutting table


20


permits fabric with minimal selvage to be trimmed and used in production. Such fabric may otherwise be scrapped, and therefore, the cutting table


20


is capable of more efficiently using the fabric.




While the invention has been illustrated by the description of one embodiment and while the embodiment has been described in considerable detail, there is no intention to restrict nor in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those who are skilled in the art. For example, in the described embodiment, the scale


40


is dimensioned with half-scale markings. As will be appreciated, in an alternative embodiment, the scale


40


can be dimensioned with full-scale markings; and the indicator


54


would be aligned with a scale marking representing one-half the desired width.




Further, in the described embodiment, the indicator


54


is mounted midway between the lines of light


108


,


110


and is used to align to a center line of the fabric or pattern with the scale


40


. As will be appreciated, in another embodiment, the indicator


54


could be mounted in alignment with the light


110


from laser


98


. With such an embodiment, the scale


40


can be dimensioned with full-scale markings.




In the described embodiment. lasers


96


,


98


project respective light beams that illuminate lines of light


108


,


110


on the fabric


26


. As will be appreciated, in other embodiments, other lasers may be used, for example, lasers that project a spot or a short line of light may also be used. In such an embodiment, a laser


98


can be used to project a spot of light at any point along the cutting path


29


. Such spot is used to identify when the indicia


112


is marked on the fabric


26


. Similarly, a spot of light from the laser


96


can be used to locate the indicia


112


after the fabric


26


has been rotated 180° and realigned against the guide


36


.




In the described embodiment, the cutting table is used to cut the fabric to a desired first dimension or width. As will be appreciated, the fabric can be rotated 90°, and the cutting table used to cut the fabric to a desired dimension in another direction, for example, to a desired length. Further, in the described embodiment, lasers


96


,


98


are used to provide the light beams


108


,


110


. As will be appreciated, in alternative embodiments, the light beams may be provided by other light emitting devices, for example, IR devices, LED's, etc.




Therefore, the invention in its broadest aspects is not limited to the specific details shown and described. Consequently, departures may be made from the details described herein without departing from the spirit and scope of the claims which follow.
