Abstract
Abstract A loom having weft insertion means in the form of three pivotally mounted arcuate members which lay loops of weft in a weft shed, and also having selvedge knitting means reciprocable alongside the warp shed. Two of the arcuate inserting members lay loops of weft in a split shed which is used for producing body tape and the third arcuate inserter is used for laying weft in a shed created for the production of pockets on the body tape. The two wefts laid in the body are brought together at an edge remote from insertion for the knitting therethrough of a catch thread to form a knitting selvedge, while the pocket weft loops are themselves knitting together to form interdigitated loops with or without a catch thread.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A loom comprising a split warp shed, three arcuate weft inserters pivotally mounted on said loom for movement through said warp shed, two of said weft inserters being adapted to lay loops of body weft yarns in the split warp shed to produce a body tape, slide means mounted for reciprocal movement along side said warp shed, said slide means including first means for bringing together the two weft loops laid in the body tape at the edge remote from the weft inserters and second means on said slide means for inserting a catch thread through said two weft loops to form a knitted selvedge along one edge, said third weft inserter being used for laying weft in a warp shed to produce pockets on said body tape, and third means on said slide means for knitting the said pocket weft to form interdigitated loops.
