Two monofilamentary polyamide coils of garland profile, each with a multiplicity of substantially planar loops carrying coupling heads, are interengageably carried on resepective marginal zones of a pair of warp-knitted stringer tapes whose fabric has a pattern of longitudinal wales and transverse courses formed by warp and weft threads, respectively. The weft threads zig-zag in interleaved relationship to form elongate undulations of generally triangular shape whose vertices define the courses, each undulation spanning a group of four wales; with these undulations pointing alternately toward and away from the tape edge confronting the other tape, alternate courses terminating short of that edge to provide a series of weft-free regions in the coil-supporting marginal zone. The loops of the coil, registering with the courses that terminate at the tape edge, are fastened to the tape by stitching which passes through the centers of the weft-free regions between wales of the marginal zone. |
