A slide-fastener element of the monofilamentary-coil type rests on a stringer tape whose main portion lies in a plane offset from the midplane of the coil. The tape, woven from a set of main warp threads and a continuous weft thread, is anchored to the coil by two sets of ancillary warp threads which respectively overlie and underlie a core traversing the turns of the coil and are interlinked by the same weft thread, the latter also passing around the core. The underlying ancillary warp threads are coplanar with the main warp threads; the overlying ancillary warp threads are more numerous than the underlying ones and envelop about half the coil from above. |
