Abstract

Abstract A thick-walled, three-dimensionally shaped fabric is produced on a circular weaving machine with the aid of a rotating filling yarn inserter. The filling yarn inserter is adaptable for placing a filling yarn in an annular shed formed by the machine by moving through a path circling the vertical axis of the fabric.

Claim 1
Independent Claim 114 words
A filling yarn inserter comprising a base, said base including a track, a plate mounted for slidable movement in said base, said plate forming a track, a tip slidably mounted in said plate track and defining a passageway, means mounted on said base and connected to said plate for selectively moving said plate relative to said base, means mounted on said plate and connected to said tip for selectively moving said tip relative to said plate, a yarn supply source mounted on said base for housing a continuous length of yarn, said yarn extending from said yarn supply source through said tip passageway and being adapted to be drawn from said yarn supply source.
Claim 2
Dependent Claim 114 words
A filling yarn inserter comprising a base, said base including a track, a plate mounted for slidable movement in said base, said plate forming a track, a tip slidably mounted in said plate track and defining a passageway, means mounted on said base and connected to said plate for selectively moving said plate relative to said base, means mounted on said plate and connected to said tip for selectively moving said tip relative to said plate, a yarn supply source mounted on said base for housing a continuous length of yarn, said yarn extending from said yarn supply source through said tip passageway and being adapted to be drawn from said yarn supply source.
Claim 3
Dependent Claim 44 words
