Abstract
Abstract A process for the manufacture of contoured pile ware on a conventional double needle bar warp knitting machine yields textured pile fabric with an unusual appearance. The pattern is formed of pile threads of different length and in different positions in the pile ribs and are bound together with the base fabric. The ware is formed on a twin bed warp knitting machine and subsequently is cut to form two individual panels.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
180 words
A process for fabricating knitted fabric having patterns formed thereon by pile threads of different lengths on a double needle bed warp knitting machine including two needle beds and a plurality of guidebars associated therewith comprising the steps of: (a) knitting the pile forming threads carried by a first guidebar about the needles forming the ground fabric on a first needle bed; (b) knitting said first guidebar pile forming threads about the needles of a second needle bed and returning to step (a); (c) knitting the pile forming threads carried by a second guidebar about the needles forming the ground fabric on said first needle bed; (d) knitting said second guidebar pile forming threads about the needles of a second needle bed and returning to step (c); said first guidebar and said second guidebar being provided with different displacements when moving between said first and second needle beds; and (e) centrally cutting said pile forming threads appearing between the fabric formed by said first and second needle bars along the entire width of said fabric to form two separate panels.
Claim 2
Dependent Claim
180 words
A process for fabricating knitted fabric having patterns formed thereon by pile threads of different lengths on a double needle bed warp knitting machine including two needle beds and a plurality of guidebars associated therewith comprising the steps of: (a) knitting the pile forming threads carried by a first guidebar about the needles forming the ground fabric on a first needle bed; (b) knitting said first guidebar pile forming threads about the needles of a second needle bed and returning to step (a); (c) knitting the pile forming threads carried by a second guidebar about the needles forming the ground fabric on said first needle bed; (d) knitting said second guidebar pile forming threads about the needles of a second needle bed and returning to step (c); said first guidebar and said second guidebar being provided with different displacements when moving between said first and second needle beds; and (e) centrally cutting said pile forming threads appearing between the fabric formed by said first and second needle bars along the entire width of said fabric to form two separate panels.
Claim 3
Dependent Claim
45 words
The process according to claim 1 wherein said pile forming threads are knitted about predetermined needle groups, said pile forming threads in the middle of said group being provided with a larger displacement than said pile forming threads at the edge of said needle group.
Claim 4
Dependent Claim
27 words
The process according to claim 2 wherein said pile forming threads are laid about the same needle groups on each said needle bed in the same manner.
Claim 5
Dependent Claim
28 words
The process according to claim 2 wherein needles utilized for the formation of base fabric disposed between said needle groups are maintained free of said pile forming threads.
Claim 6
Dependent Claim
32 words
The process according to claim 4 wherein said needles maintained free of pile forming threads in said first needle bed are displaced relative to the corresponding needles in said second needle bed.
Claim 7
Dependent Claim
36 words
The process according to claim 2 wherein said pile forming threads of a first needle group in said first needle bed are laid across needles from at least two needle groups in said second needle bed.
Claim 8
Dependent Claim
13 words
The process according to claim 1 wherein said pile threads cross each other.
Claim 9
Dependent Claim
33 words
The process according to claim 1 wherein said pile forming threads laid about a first needle in said first needle bed are laid across at least two needles in said second needle bed.
Claim 10
Dependent Claim
15 words
Pile fabric fabricated according to claim 1 wherein said pile threads are of different lengths.
Claim 11
Dependent Claim
27 words
Pile fabric according to claim 9 wherein pile threads disposed in adjacent stitches of the ground ware in the direction of the warp are the same length.
Claim 12
Dependent Claim
22 words
Pile fabric according to claim 9 wherein said pile threads are of different lengths and form a zig-zag or non-linear ribbed pattern.
Claim 13
Dependent Claim
25 words
Pile fabric according to claim 9 made in the form of velour wherein the pattern effect is formed by said pile threads having different lengths.
Claim 14
Dependent Claim
27 words
Pile fabric according to claim 9 wherein said pile thread length is shorter at the edge of a pattern and longer in the middle of the pattern.
