FIELD OF THE INVENTION




The present invention relates generally to decorative grass and methods for making same, and more particularly, but not by way of limitation, to a decorative grass having printed matter thereon and to a method for producing same. In one aspect, the present invention relates to a decorative grass having an embossed pattern thereon and to a method for producing same. In yet another aspect, the present invention relates to a decorative grass having an embossed pattern and printed matter thereon and to a method for producing same.




BRIEF DESCRIPTION OF PRIOR ART




Decorative grass has been used for many years in Easter baskets and for other decorative purposes. The decorative grass of the prior art has been produced by numerous methods and from a variety of materials such as plastic materials, paper, cellophane or the like. Typically, such materials are cut and shredded to produce segments having predetermined dimensions. One such prior art method for making decorative grass is disclosed in U.S. Pat. No. 4,292,266, issued to Weder et al., wherein a plastic film is extruded and cut into plastic strips which are passed through a slow-speed godet, an oven and a high-speed godet so that the strips are drawn down in width and thickness without breaking. From the high-speed godet, the strips or strands are chopped to a desired length and conveyed to a storage area for subsequent bagging and packaging.




While the prior art methods for making decorative grass have been widely accepted, new and improved methods for making decorative grass having improved aesthetic qualities are being sought which are less costly and wherein the decorative grass has an improved feel. It is to such a decorative grass and method for producing same that the present invention is directed.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




Referring now to the drawings,

FIG. 1

illustrates schematically a system


10


for making a decorative grass


12


having printed matter on at least one side thereof in accordance with the present invention. A roll of material


14


consisting of a flexible sheet or web of material


16


having a first or upper surface


18


and a second or lower surface


20


is rollingly supported so that the sheet of material


16


is passed by an ink roller


22


which is rotated in the direction indicated by the arrow


24


so that ink is applied to selected portions of the upper surface


18


of the sheet of material


16


to provide a printed sheet of material


26


having a printed design and/or printed material


28


on the upper surface


18


thereof (FIG.


2


A), such as a star, a flower design, an animal design and the like, or a special occasion slogan, i.e., happy birthday, an anniversary, Merry Christmas, Happy Mother's Day and the like, or a combination of a printed design and a printed material. The printed design and/or printed material


28


can be selectively printed on the upper surface


18


of the sheet of material


16


by application of ink to the upper surface


18


of the sheet of material


16


(

FIG. 2A

) so that when the sheet of material


26


is slit (such as along dashed lines


29


) and cut into segments to form the decorative grass


12


, each segment of the decorative grass


12


contains the printed material and/or printed designs


28


which are confined within the boundaries of the segments of decorative grass


12


substantially as shown in FIG.

A.




As an alternative, a printed design and/or printed material


28




a


can be randomly printed on an upper surface


18




a


of a sheet of material by application of ink to provide a printed sheet of material


26




a


(

FIG. 2B

) so that, when the sheet of printed material


26




a


is slit (such as along dashed lines


29




a


) and cut into segments to form the decorative grass


12




a


, each segment of the decorative grass


12




a


contains at least a portion of the printed design and/or printed material


28




a


substantially as shown in FIG.

It should be understood that while the ink roller


22


has been illustrated as being positioned so as to apply ink to the upper surface


18


of the sheet of material


16


, the ink roller


22


can be positioned so as to apply ink to the lower surface


20


of the sheet of material


16


or two or more ink rollers


22


can be employed to apply ink to either the upper surface


18


of the sheet of material


16


or to the lower surface


20


of the sheet of material


16


, or to apply ink to the upper and lower surfaces


18


and


20


of the sheet of material


16


. Further, when employing two or more of the ink rollers


22


to apply ink to the sheet of material


16


, different colors of ink can be applied to either the upper surface


18


of the sheet of material


16


, or to the lower surface


20


of the sheet of material


16


, or to the upper and lower surfaces


18


and


20


of the sheet of material


16


.




The sheets or webs of material employed to provide the printed sheets of material


26


,


26




a


and


26




b


from which the decorative grasses


12


,


12




a


and


12




b


herein before described are produced are substantially identical in construction, as are the systems for making decorative grasses from such printed sheets of material. Thus, only the sheet of material


16


and the system


10


for producing the decorative grass


12


will be described in detail herein after with reference to FIG.


1


.




The sheet of material


16


can be constructed of any suitable material capable of having ink affixed thereto so that the printed design and/or printed material


28


can be printed on the sheet of material


16


to produce the sheet of printed material


26


. Illustrative of materials which can be employed as the sheet of material


16


are polymeric film, paper, foil, iridescent materials, optical effect materials and combinations thereof, such as laminated materials.




When the sheet of material


16


is a laminated material and only one surface of the sheet of material


16


is to be printed to produce the sheet of printed material


26


, only the side being printed with the printed design and/or printed material must be capable of having the ink affixed thereto.




When the sheet of material


16


is a polymeric film, a flexible sheet of liquified thermoplastic film can be extruded from an extruder in a conventional and well known manner. The flexible sheet of liquified thermoplastic film can then be passed through a cooler which cools the liquified thermoplastic film into a sheet of solidified thermoplastic film, i.e. the sheet of material


16


. The sheet of solidified thermoplastic film is then printed in the manner herein before discussed to provide the printed sheet of material


26


.




The printed sheet of material


26


is then passed through a drier


30


to produce a dried printed sheet of material


32


. The dried printed sheet of material


32


is then passed through a slitter


34


, which slits or cuts the dried printed sheet of material


32


into strips or strands of desired width to produce a slitted web


36


. The slitted web


36


is then passed into a chopper unit


38


where the slitted web


36


is chopped into segments to produce the decorative grass


12


(

FIGS. 1 and 3A

) having a predetermined length and which has the desired printed material


28


thereon.




When employing a sheet of solidified thermoplastic film to produce the printed sheet of material


26


, and depending on the ink pattern applied to the sheet of material


16


, it may be desirable after passing the printed sheet of material


26


through the slitter


34


, and prior to passage of the slitted web


36


into the chopper unit


38


, to heat the slitted web


36


in order to soften the strips or stands of the slitted web


36


so that the strips or strands of the slitted web


36


can be drawn down to provide the strips or strands of the slitted web


36


with a desired width and thickness as described in U.S. Pat. No. 4,292,266 which is herein specifically incorporated by reference.




The decorative grasses


12


produced by passing the slitted web


36


through the chopper unit


38


can then be conveyed to a storage area (not shown) which may be in the form of a suitable bin, conveyed to a packaging machine or to a baling machine for baling prior to storage. As other alternatives, the decorative grasses


12


may be placed into boxes or cartons, subjected to further processing immediately or held for subsequent processing.




Referring now to

FIG. 3A

, a segment


40


of the decorative grass


12


is illustrated. The segment


40


of the decorative grass


12


is provided with an upper surface


42


having the printed design and/or printed material


28


thereon and a lower surface


44


. The segment


40


has a width


46


and a length


48


which define the boundaries of the segment


40


; and the printed design and/or printed material


28


is confined within the boundaries of the segment


40


of the decorative grass


12


. The width


46


and length


48


of the segment


40


are determined by the processing conditions of the system


10


, i.e. the operational parameters of the slitter


34


and the chopper unit


38


. The width


46


and length


48


, as well as thickness


50


of the segment


40


can vary widely and will generally be dependent on the requirements of individual consumers. For most uses, however, the segment


40


will have a width


46


of from about 0.020 inches to about 0.125 inches, a length


48


of from about 2 inches through 24 inches and a thickness


50


of from about 0.0005 inches to about 0.0030 inches.




The segments of the decorative grass


12


, such as the segment


40


, can be produced clear or in almost any color required and the colors can be transparent or opaque, including but not exclusively red, green, yellow, pink, orchid, and blue.




Referring now to

FIG. 3B

, another embodiment of a segment


40




a


of a decorative grass


12




a


is illustrated. The segment


40




a


of the decorative grass


12




a


is provided with an upper surface


42




a


and a lower surface


44




a


. The upper surface


42




a


is provided with randomly positioned printed designs and/or printed materials


28




a


. The segment


40




a


has a width


46




a


and a length


48




a


which define the boundaries of the segment


40




a


; and only portions of at least a portion of the printed design and/or printed material


28




a


are confined within the boundaries of the segment


40




a


of the decorative grass


12




a


. The width


46




a


, length


48




a


and thickness


50




a


of the segment


40




a


are determined by the processing conditions; and can vary widely. For most uses, however, the segment


40




a


will have a width


46




a


of from about 0.020 inches to about 0.125 inches, a length


48




a


of from about 2 inches through 24 inches and a thickness


50




a


of from about 0.0005 inches to about 0.0030 inches.




The segments of the decorative grass


12




a


, such as the segment


40




a


, can be produced clear or in almost any color required and the colors can be transparent or opaque including but not exclusively red, green, yellow, pink, orchid and blue.




Referring now to

FIG. 3C

, a plurality of segments of a decorative grass


12




b


are illustrated, such as segments


40




b


and


40




b


′. The segments


40




b


and


40




b


′ are produced in the same manner as the segment


40


of the decorative grass


12


hereinbefore described with reference to

FIG. 1

, with the exception that, in the production of the printed sheet of material


26




b


(FIG.

C), two or more ink rollers are employed which apply different colors of ink on the upper surface and/or lower surfaces


18




b


and


20




b


of a sheet or web of material to provide the printed sheet of material


26




b


illustrated in FIG.


2


B. Thus, upon processing the printed sheet of material


26




b


, colored segments of decorative grass


12




b


having different colors, such as the segments


40




b


and


40




b


′, are produced which cooperate to provided the decorative grass


12




b


with an appearance simulating blended segments of decorative grass. Thus, in a single production run, a blend-appearing decorative grass


12




b


having segments of different colors, such as the decorative grass


12




b


containing different segments


40




b


and


40




b


′ can be produced.




The segment


40




b


has a colored upper surface


42




b


and a lower surface


44




b


; and the segment


40




b


has a width


46




b


and a length


48




b


, each of which are determined by the processing conditions employed in the production of the decorative grass


12




b


. Similarly, the segment


40




b


′ has a colored upper surface


42




b


′ and a lower surface


44




b


′; and the segment


40




b


′ has a width


46




b

48




b


′, each of which are determined by the processing conditions of the system


10


, i.e. the operational parameters of the slitter


34


and the chopper unit


38


. The colored upper surface


42




b


of the segment


40




b


is a different color than the colored upper surface


42




b


′ of the segment


40




b


′ so that decorative grass


12




b


containing a plurality of the segments


42




b


and


42




b


′ has the appearance of a blended decorative grass.




The widths


46




b


and


46




b


′, the lengths


48




b


and


48




b


′ and thicknesses


50




b


and


50




b


′, respectively, of the segments


40




b


and


40




b


′ can vary widely and will generally be dependent on the requirements of individual consumers. For most uses, however, the segments


40




b


and


40




b


′ will have a width


46




b


or


46




b


′ of from about 0.020 inches to about 0.125 inches, a length


48




b


or


48




b


′ of from about 2 inches through 24 inches and a thickness


50




b


or


50




b

The segments


40




b


and


40




b


′ of the decorative grass


12




b


can be produced in almost any color and the colors can be transparent or opaque including but not exclusively red, green, yellow, pink, orchid and blue.




Referring now to

FIG. 4

, a system


70


for making a decorative grass


72


having an embossed pattern


74


(

FIG. 5

) in accordance with the present invention is schematically illustrated. A roll of material


76


(which consists of a flexible sheet or web of material


78


having a first or upper surface


80


and a second or lower surface


82


) is rollingly supported so that the sheet of material


78


is passed between embossing rollers


84


and


86


which are rotated in the direction indicated by the arrows


88


and


90


, respectively. The embossing roller


84


has a plurality of raised portions


92


(only one of the raised portions


92


being designated by the reference numeral in FIG.


4


); and the embossing roller


86


has a plurality of depressed portions


94


(only one of the depressed portions


94


being designated by the reference numeral in FIG.


4


). The depressed portions


94


are arranged on the embossing roller


86


to correspond and register with the raised portions


92


on the embossing roller


84


. Thus, as the sheet of material


78


is passed between the embossing rollers


84


and


86


, the raised portions


92


of the embossing roller


84


engage the sheet of material


78


and force the sheet of material


78


into the corresponding depressed portions


94


of the embossing roller


86


thereby forming raised portions


96


and depressed portions


98


in the sheet of material


78


as depicted in FIG.


4


. That is, passage of the sheet of material


78


between the embossing rollers


84


and


86


produces an embossed sheet of material


100


.




The embossed sheet of material


100


is then passed through a slitter


102


, which slits or cuts the embossed sheet of material


100


into strips or strands of desired width to produce a slitted web


104


. The slitted web


104


is then passed into a chopper unit


106


where the slitted web


104


is chopped to produce the embossed decorative grass


72


(

FIG. 5

) having a predetermined length and width.




The embossed decorative grass


72


produced by passing the slitted web


104


through the chopper unit


106


can then be conveyed to a storage area (not shown) which may be in the form of a suitable bin, conveyed to a packaging machine or to a baling machine for baling prior to storage. As other alternatives, the embossed decorative grass


72


may be placed into boxes or cartons, subjected to further processing immediately or held for subsequent processing.




The sheet of material


78


can constructed of any suitable material capable of being embossed. Illustrative of material which can be employed as the sheet of material


78


are polymeric film, paper, foil, iridescent materials, optical effect materials and combinations thereof, such as laminated materials.




Referring now to

FIG. 6

, a system


110


for making a decorative grass


112


having an embossed pattern


114


and a printed design and/or printed material


116


(

FIG. 7

) in accordance with the present invention is schematically illustrated wherein the printed material


116


is out of registry with the embossed pattern


114


. A roll of material


118


consisting of a flexible sheet of material


120


having a first or upper surface


122


and a second or lower surface


124


is rollingly supported so that the sheet of material


120


is passed by an ink roller


126


which is rotated in the direction indicated by the arrow


128


so that ink is applied to selected portions of the upper surface


122


of the sheet of material


120


to provide a printed sheet of material


130


having the printed material


116


on the upper surface


122


thereof. The printed material


116


can be a printed design and/or printed material such as a star, a flower, an animal and the like, or a special occasion slogan, i.e., happy birthday, an anniversary, Merry Christmas, Happy Mother's Day and the like, or a combination of a printed design and a special occasion slogan.




It should be understood that while the ink roller


126


has been illustrated as being positioned so as to apply ink to the upper surface


122


of the sheet of material


120


, the ink roller


126


can be positioned so as to apply ink to the lower surface


124


of the sheet of material


120


or two or more ink rollers


126


can be employed to apply ink to either the upper surface


122


of the sheet of material


120


or to the lower surface


124


of the sheet of material


120


, or to apply ink to the upper and lower surfaces


122


and


124


of the sheet of material


120


. Further, when employing two of more of the ink rollers


126


to apply ink to the sheet of material


120


, different colors of ink can be applied to either the upper surface


122


of the sheet of material


120


, or to the lower surface


124


of the sheet of material


120


, or to the upper and lower surfaces


122


and


124


of the sheet of material


120


.




The printed sheet of material


130


is then passed through a drier


132


to dry and affix the ink and thereby produce a dried printed sheet of material


134


. The dried printed sheet of material


134


is then passed between embossing rollers


136


and


138


which are rotated in the direction indicated by the arrows


140


and


142


, respectively. The embossing roller


136


has a plurality of raised portions


144


(only one of the raised portions


144


being designated by the reference numeral in FIG.


6


); and the embossing roller


138


has a plurality of depressed portions


146


(only one of the depressed portions


146


being designated by the reference numeral in FIG.


6


). The depressed portions


146


are arranged on the embossing roller


138


to correspond and register with the raised portions


144


on the embossing roller


136


. Thus, as the dried printed sheet of material


134


is passed between the embossing rollers


136


and


138


, the raised portions


144


of the embossing roller


136


engage the dried printed sheet of material


134


and force the dried printed sheet of material


134


into the corresponding depressed portions


146


of the embossing roller


138


thereby forming a sheet of printed and embossed material


148


having raised portions


150


and depressed portions


152


.




The printed and embossed sheet of material


148


is then passed through a slitter


154


, which slits or cuts the printed and embossed sheet of material


148


into strips or strands of desired width to produce a slitted web


156


. The slitted web


156


is then passed into a chopper unit


158


where the slitted web


156


is chopped to produce the decorative grass


112


(

FIG. 7

) having the embossed pattern


114


, the printed material or pattern


116


and a predetermined length and width.




The decorative grass


112


produced by passing the slitted web


156


through the chopper unit


158


can then be conveyed to a storage area (not shown) which may be in the form of a suitable bin, conveyed to a packaging machine or to a baling machine for baling prior to storage. As other alternatives, the decorative grass


112


may be placed into boxes or cartons, subjected to further processing immediately or held for subsequent processing.




The sheet of material


120


can constructed of any suitable material capable of being printed and embossed. Illustrative of material which can be employed as the sheet of material


120


are polymeric film, paper, foil, iridescent materials, optical effect materials and combinations thereof, such as laminated materials.




When the sheet of material


120


is a laminated material and only one surface of the sheet of material


120


is to be printed to produce the sheet of printed material


130


, only the side being printed with the printed design and/or printed material must be capable of having the ink affixed thereto.




When the sheet of material


120


is a polymeric film, a flexible sheet of liquified thermoplastic film can be extruded from an extruder in a conventional and well known manner. The flexible sheet of liquified thermoplastic film can then be passed through a cooler which cools the liquified thermoplastic film into a sheet of solidified thermoplastic film, i.e. the sheet of material


120


. The sheet of solidified thermoplastic film is then printed and embossed in the manner herein before discussed to provide the printed and embossed sheet of material


148


.





FIG. 7

is a perspective view of a segment


160


of the decorative grass


112


having the embossed pattern


114


and printed material


116


thereon constructed in accordance with the present invention wherein the printed material


116


is out of registry with the embossed pattern


114


. The term “out of registry” as used herein is to be understood to mean that the embossed pattern or a portion of the embossed pattern is arbitrarily positioned with respect to the printed material on the segments of the decorative grass


112


such as is illustrated in FIG.


7


. That is, the embossed pattern


114


produced by embossing the dried printed sheet of material


134


is randomly positioned on the dried printed sheet of material


134


relative to the printed material


116


. Thus, when the printed and embossed sheet of material


148


is slit and chopped into segments


160


of the decorative grass


112


, the embossed pattern


114


is randomly positioned on the segments


160


of the decorative grass


112


relative to the printed material


116


thereon.





FIG. 8

illustrates schematically another system


170


for producing a decorative grass


172


having an embossed pattern


174


and printed material or pattern


176


(

FIG. 9

) in accordance with the present invention wherein the printed material


176


is in registry with the embossed pattern


174


. A roll of material


178


consisting of a flexible sheet or web of material


180


having a first or upper surface


182


and a second or lower surface


184


is rollingly supported so that the sheet of material


180


is passed between a pair of embossing rollers


186


and


188


. The embossing roller


186


has a plurality of raised portions


190


(only one of the raised portions


190


being designated as the reference numeral in FIG.


8


). The embossing roller


188


has a plurality of depressed portions


192


(one of the depressed portions


192


being designated as the reference numeral in FIG.


8


). The depressed portions


192


are arranged on the embossing roller


188


to correspond and register with the raised portions


190


on the embossing roller


186


. An ink roller


194


is disposed near the embossing roller


186


and positioned to apply ink to the raised portions


190


of the embossing roller


186


.




The sheet of material


180


is passed between the embossing rollers


186


and


188


in the direction indicated by the arrow


196


and the embossing rollers


186


and


188


are rotated in the direction indicated by the arrows


198


and


200


, respectively. As the sheet of material


180


is passed between the embossing rollers


186


and


188


, the raised portions


190


on the embossing roller


186


engage the sheet of material


180


and force the sheet of material


180


into the corresponding depressed portion


192


of the embossing roller


188


thereby forming raised portions


202


and depressed portions


204


in the sheet of material


180


. The ink roller


194


rotates in a direction indicated by the arrow


206


and applies ink to the raised portions


190


of the embossing roller


186


. The raised portions


190


of the embossing roller


186


having the ink thereon transfer the ink to the sheet of material


180


thereby applying a color or printed material to the raised portions


202


of the sheet of material


180


simultaneously with forming the raised portions


202


to provide an embossed, printed sheet of material


208


wherein the embossed pattern


174


and the printed material


176


of the embossed printed sheet of material


208


are in registry.




The term “in registry” as used herein is to be understood to mean that the embossed pattern and the printed material are positioned on the embossed, printed sheet of material in predetermined positions so that the embossed pattern and the printed material are disposed within the confines of a unitary design. For example,

FIG. 9

illustrates a unitary pattern or design containing the embossed pattern


174


and the printed material


176


which are within the confines of the unitary pattern or design.




The embossed, printed sheet of material


208


is then passed through a drier


210


to produce a dried embossed printed sheet of material


212


. The dried embossed printed sheet of material


212


is then passed through a slitter


214


, which slits or cuts the dried embossed printed sheet of material


212


into strips or strands of desired width to produce a slitted web of material


216


. The slitted web of material


216


is then passed into a chopper unit


218


where the slitted web


216


is chopped into segments


220


to produce the decorative grass


172


(

FIG. 9

) having a predetermined length and width and which have the embossed pattern


174


in registry with the printed material


176


. It should be noted that by controlling the embossing and printing of the sheet of material


180


to produce the embossed printed sheet of material


208


, as well as the slitting of the dried embossed printed sheet of material


212


by passage of same through the slitter


214


, the unitary patterns or designs comprising the embossed pattern


174


in register with the printed material


176


can be controlled to lie within the boundaries of the segments


220


constituting the decorative grass


172


, or the unitary patterns or designs may be randomly positioned on the sheet of material


180


so that only portions of the unitary patterns or designs lie within the boundaries of the segments constituting the decorative grass


172


. The decorative grass


172


produced by passing the slitted web


216


through the chopper unit


218


can then be conveyed to a storage area (not shown) which may be in the form of a suitable bin, conveyed to a packaging machine or to a baling machine for baling prior to storage. As other alternatives, the decorative grass


172


may be placed into boxes or cartons, subjected to further processing immediately or held for subsequent processing.




The sheet of material


180


can constructed of any suitable material capable of being printed and embossed. Illustrative of material which can be employed as the sheet of material


180


are polymeric film, paper, foil, iridescent materials, optical effect materials and combinations thereof, such as laminated materials.




When the sheet of material


180


is a laminated material and only one surface of the sheet of material


180


is to be printed to produce the embossed printed sheet of material


208


, only the side being printed with the printed design and/or printed material


176


must be capable of having the ink affixed thereto.




When the sheet of material


180


is a polymeric film, a flexible sheet of liquified thermoplastic film can be extruded from an extruder in a conventional and well known manner. The flexible sheet of liquified thermoplastic film can then be passed through a cooler which cools the liquified thermoplastic film into a sheet of solidified thermoplastic film, i.e. the sheet of material


180


. The sheet of solidified thermoplastic film is then printed and embossed in the manner herein before discussed to provide the embossed printed sheet of material


208


.
