Abstract

Abstract Warp knitting machine having a zone wherein needles are disposed and means for supplying warp threads to the needles includes a device for filling a weft having first holder members for making the weft ready outside the needle zone, means for guiding the weft to the warp threads comprising a thread guide cooperating therewith for making the weft ready, the thread guide being displaceable in a closed travel path, means for feeding a plurality of wefts selectively to the thread guide for entrainment thereby in the closed travel path thereof, the thread guide having a clamping member for individually gripping the thread for each weft, second holder means located adjacent the travel path of the thread guide and adapted to receive from the latter the weft gripped by the clamping member, and a severing member coordinated with the first holder members for cutting into predetermined lengths the weft to be made ready, the severing member being connected to the displacement thread guide.

Claim 1
Independent Claim 157 words
Warp knitting machine having a zone wherein needles are disposed and means for supplying warp threads to the needles comprising a device for filling a weft having first holder members for making the weft ready outside the needle zone, said first holder members having a thread guide cooperating therewith for making the weft ready, said thread guide being displaceable in a closed travel path, means for feeding a plurality of wefts selectively to said thread guide for entrainment thereby in said closed travel path thereof, said thread guide having a clamping member for individually gripping the thread for each weft, second holder means located adjacent the travel path of said thread guide and adapted to receive from the latter the weft gripped by said clamping member, and a severing member coordinated with said first holder members for cutting into predetermined lengths the weft to be made ready, said severing member being connected to said displaceable thread guide.
Claim 2
Dependent Claim 157 words
Warp knitting machine having a zone wherein needles are disposed and means for supplying warp threads to the needles comprising a device for filling a weft having first holder members for making the weft ready outside the needle zone, said first holder members having a thread guide cooperating therewith for making the weft ready, said thread guide being displaceable in a closed travel path, means for feeding a plurality of wefts selectively to said thread guide for entrainment thereby in said closed travel path thereof, said thread guide having a clamping member for individually gripping the thread for each weft, second holder means located adjacent the travel path of said thread guide and adapted to receive from the latter the weft gripped by said clamping member, and a severing member coordinated with said first holder members for cutting into predetermined lengths the weft to be made ready, said severing member being connected to said displaceable thread guide.
Claim 3
Dependent Claim 38 words
Warp knitting machine according to claim 1 wherein said weft-severing member is secured to said thread guide in a region wherein the weft extends from said thread guide to a location at which finished fabric web is disposed.
Claim 4
Dependent Claim 17 words
Warp knitting machine according to claim 1 wherein said thread guide is constructed as a clamping shears.
Claim 5
Dependent Claim 30 words
Warp knitting machine according to claim 1 wherein said means for feeding a plurality of wefts comprises a plurality of separate thread feeders mounted turret-like in a common adjusting member.
Claim 6
Dependent Claim 57 words
Warp knitting machine according to claim 1 wherein said means for feeding a plurality of wefts comprises a plurality of separate thread feeders, said first holder members and said thread feeders being disposed so as to define a feed path for the wefts therebetween extending in direction substantially perpendicular to said travel path of said thread guide.
