A pair of parallel tapes are simultaneously knit on a warp-knitting machine with a connecting filament joining their confronting edges. Each tape is formed by a plurality of warp chains laterally interconnected by laid-in weft filaments which span at least three of the wales formed by the chains. The continuous coupling elements are each connected to one of the confronting edges, and the connecting filament is broken either after or immediately before the attaching operation. This connecting filament can be tensioned to be tighter than either the warp or weft filaments to form openings in the tapes adjacent the edge wale. The stitching can pass through these openings, or the coupling heads of the elements can be pushed therethrough. Cutting of this tensioned filament after attachment of the coupling elements substantially closes the openings and causes the tape edge to fold back over the stitching or coupling-turn bights. |
