Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 165 words
In a warp knitting machine with devices for handling long weft threads and for feeding the threads to knitting tools of the machine and a guide bar carrying a plurality of eye needles having elongated shanks, means to support in separated relation weft threads fed to and extending along the knitting tools, at least one formed sinker also carried by the guide bar and comprising a pair of tongue-like support members extending at predetermined mutual spacing substantially parallel to one another and substantially perpendicularly to the shank of at least one of the eye needles of the guide bar, said support members having respective free ends defining an opening for the space between said substantially parallel support members, said opening facing in a direction toward said support means for the weft thread, said support members and said weft thread support means being relatively displaceable so as to transfer respective weft threads from said support means through said opening into the space between said support members.
