Abstract
Abstract A right-right warp knitting machine capable of providing pile fabrics such as velour includes two needle beds, each needle bed producing one fabric panel, utilizes one guide bar supplying a ground thread and at least a second guide bar for providing a pile thread. The panels may be connected together by a common thread which is cut after the completion of the fabric panels thereby forming two separate independent fabric panels having at least one velour surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A process for manufacturing textured ware, such as pile fabrics, velour fabrics and combinations thereof, or the like on a warp knitting machine having first and second needle beds with a plurality of needles requiring external closing means disposed thereon, for producing a fabric panel on each said needle bed, first and second closing means adapted to cooperate with said needles for opening and closing said needles in a predetermined time sequence, and two first and two second guides for laying thread about said needles in said first and said second needle beds, respectively, comprising the steps of: (a) simultaneously laying a first thread about a first needle in said first and second needle beds by said first guides each working cycle for the formation of a stitch; and (b) periodically skipping the laying of a second thread about a second adjacent needle in said first and second needle bed by said second guides during said working cycle the laying of said first and second threads occuring in a predetermined time sequence.
Claim 2
Dependent Claim
172 words
A process for manufacturing textured ware, such as pile fabrics, velour fabrics and combinations thereof, or the like on a warp knitting machine having first and second needle beds with a plurality of needles requiring external closing means disposed thereon, for producing a fabric panel on each said needle bed, first and second closing means adapted to cooperate with said needles for opening and closing said needles in a predetermined time sequence, and two first and two second guides for laying thread about said needles in said first and said second needle beds, respectively, comprising the steps of: (a) simultaneously laying a first thread about a first needle in said first and second needle beds by said first guides each working cycle for the formation of a stitch; and (b) periodically skipping the laying of a second thread about a second adjacent needle in said first and second needle bed by said second guides during said working cycle the laying of said first and second threads occuring in a predetermined time sequence.
Claim 3
Dependent Claim
30 words
A process according to claim 1 further including the step of: (c) using two thread guides to lay different loops during the same work cycle about the same second needle.
Claim 4
Dependent Claim
22 words
A process according to claim 1 further including the step of: (e) providing said warp knitting machine needles with sliders as closers.
Claim 5
Dependent Claim
32 words
A process according to claim 1 further including, the steps of: (f) providing said warp knitting machine needles with compound needles; and (g) providing said machine with knockover sinkers to cooperate therewith.
Claim 6
Dependent Claim
23 words
A process according to claim 1 further including the step of: (h) controlling at least one of said guides by a jacquard mechanism.
Claim 7
Dependent Claim
252 words
A process for manufacturing textured ware, such a pile fabrics, velour fabrics, and combinations thereof, or the like on a warp knitting machine, having first and second needle beds with a plurality of needles requiring external closing means disposed thereon, for producing a fabric panel on each said needle bed, first and second closing means adapted to cooperate with said needles for opening and closing said needles in a predetermined time sequence, and two first and two second guides for laying thread about said needles in said first and said second needle beds, respectively, being alternatively swingable between said first and said second needle beds, comprising the steps of: (a) laying a first thread about a first needle in said first and second needle beds by said first guides each working cycle for the formation of a stitch, leaving a second needle adjacent to said first needle free of said first thread; and (b) occasionally laying a second thread about said first needles and about said second needles in said first and said second needle beds by said second guides for tying off by said first needles by said first threads during said working cycle and being knocked off from said second needles in a later working cycle as a pile loop; said laying of thread occuring in a predetermined time sequence, said first threads providing the ground work of said panels and said second threads forming relatively small pile loops when laid across a second needle on the same needle bar.
Claim 8
Dependent Claim
252 words
A process for manufacturing textured ware, such a pile fabrics, velour fabrics, and combinations thereof, or the like on a warp knitting machine, having first and second needle beds with a plurality of needles requiring external closing means disposed thereon, for producing a fabric panel on each said needle bed, first and second closing means adapted to cooperate with said needles for opening and closing said needles in a predetermined time sequence, and two first and two second guides for laying thread about said needles in said first and said second needle beds, respectively, being alternatively swingable between said first and said second needle beds, comprising the steps of: (a) laying a first thread about a first needle in said first and second needle beds by said first guides each working cycle for the formation of a stitch, leaving a second needle adjacent to said first needle free of said first thread; and (b) occasionally laying a second thread about said first needles and about said second needles in said first and said second needle beds by said second guides for tying off by said first needles by said first threads during said working cycle and being knocked off from said second needles in a later working cycle as a pile loop; said laying of thread occuring in a predetermined time sequence, said first threads providing the ground work of said panels and said second threads forming relatively small pile loops when laid across a second needle on the same needle bar.
Claim 9
Dependent Claim
26 words
A process according to claims 1, or 6 further including the steps of: (i) forming said pile loops on the left side of said fabric panel.
Claim 10
Dependent Claim
26 words
A process according to claims 1, or 6 further including the step of: (j) forming said pile loops on the right side of said fabric panels.
Claim 11
Dependent Claim
37 words
A process according to claims 1, or 6 further including the steps of: (k) forming said pile loops on the left side of one of said panels and the right side of the other of said panels.
Claim 12
Dependent Claim
55 words
A process according to claims 1, or 6 further including the steps of: (l) alternately swinging said needle guides between said first and said second needle beds and locking the thread carried by said needle guides to only one fabric panel; and (i) forming said pile loops on the left side of said fabric panels.
