Abstract
Abstract A warp-knitting machine for furnishing a base material with a knitted fabric on both sides thereof in which the base material is supported at one side thereof, a plurality of needles adapted to penetrate reciprocably between selected threads in the base material, the base material on at least one side thereof is supported by additional threads disposed in close proximity to an upper portion of the base material above the penetration of the needles, the additional threads provide a support for the base material by remaining in close proximity thereto under a predetermined tension.

Claim 1
Independent Claim
368 words
In a warp-knitting machine for manufacturing a textile fabric including a base material, a knitted material covering at least one side of the base material and warp threads attached to the base material by a plurality of stitches disposed on one side of said base material, said machine comprising a stitch-forming zone, knitting needles positioned so that their operating paths reciprocate transversely through the base material in the stitchforming zone, means for guiding a thread onto each of the needles so that the needles form the threads which the needles carry into stitches as the needles reciprocate in the stitch-forming zone, means for feeding a plurality of warp threads to positions between the base material and the forward extremity of reciprocation of the needles so that the stitches which are formed by the needles attach the warp threads to the base material, support means disposed on the side of the base material opposite the side to which the warp threads are fed in the region where the base material approaches the knitting zone and in the region where the textile fabric leaves the knitting zone and further support means to restrain the base material against the forward movement of the knitting needles, a first of the further support means being disposed at the side of the base material to which the warp threads are fed and in the region where the base material is fed to the knitting zone and a second of the further support means being disposed at the side of the base material to which the warp threads are fed and in the region where said finished textile leaves the knitting zone, the improvement comprising tensioning means for said warp threads, said tensioning means being positioned before the knitting zone and at the side of the base material to which the warp threads are fed to hold the warp threads under tension in abutment with the side of the base material as the base material approaches and passes through the knitting zone, said tensioning means thereby constituting said first further support means and the knitting zone being free of support means on the side of the base mateRial to which the warp threads are fed.

Claim 3
Dependent Claim
21 words
A warp-knitting machine according to claim 1, in which said tensioning means comprises a guide for each of the warp threads.
Claim 4
Dependent Claim
63 words
A warp-knitting machine according to claim 2, in which each of said warp thread guides comprises an eye portion for receiving one of the warp threads and downstream from the eye portion a hook portion for holding the warp thread in abutment with the side of the base material in a longitudinal orientation parallel to the direction of travel of the base material.
Claim 5
Dependent Claim
23 words
A warp-knitting machine according to claim 3, in which the eye portion is spaced further than the hook portion from the base material.
Claim 6
Dependent Claim
34 words
A warp-knitting machine according to claim 3, in which the hook portion of each warp thread guide is positioned to receive a warp thread from the eye portion of an adjacent warp thread guide.
Claim 7
Dependent Claim
33 words
A warp-knitting machine according to claim 4, in which the hook portion of each warp thread guide is positioned to receive a warp thread from the eye portion of an adjacent warp-thread guide.
Claim 8
Dependent Claim
188 words
In a warp-knitting machine comprising at least one knitting needle, means for supporting a base material with a side of the base material facing the needle and transverse to the operating path of the needle, means for feeding a thread to the needle, means for reciprocating the needle so that the needle passes through the base material and thereby knits the thread through the base material with portions of the thread extending to the other side of the base material, and means for guiding at least one warp thread to said other side of the base material in the zone of the knitting so that said warp thread is fastened to said other side by the knitting, the improvement comprising tensioning means for the warp thread, said tensioning means being positioned outside the knitting zone and facing said other side to hold the warp threads under tension in abutment with said other side in the knitting zone thereby to cause said warp threads to restrain the base material against the forward thrust of the needle, the knitting zone being free of means for thus restraining the base material.
Claim 9
Dependent Claim
188 words
In a warp-knitting machine comprising at least one knitting needle, means for supporting a base material with a side of the base material facing the needle and transverse to the operating path of the needle, means for feeding a thread to the needle, means for reciprocating the needle so that the needle passes through the base material and thereby knits the thread through the base material with portions of the thread extending to the other side of the base material, and means for guiding at least one warp thread to said other side of the base material in the zone of the knitting so that said warp thread is fastened to said other side by the knitting, the improvement comprising tensioning means for the warp thread, said tensioning means being positioned outside the knitting zone and facing said other side to hold the warp threads under tension in abutment with said other side in the knitting zone thereby to cause said warp threads to restrain the base material against the forward thrust of the needle, the knitting zone being free of means for thus restraining the base material.
Claim 10
Dependent Claim
19 words
