A method for manufacturing a fabric tape for use in making sliding-clasp fasteners in which, during manufacture of the tape on a shuttleless loom, a spiral element which forms the teeth of the fastener is fed on to a marginal part of the tape opposite a selvedge. At least one warp thread in the marginal part of the tape is controlled by a heald and associated cam to form loops which project through and above the spiral element, and the loops, possibly together with a locking thread, are connected by an auxiliary lock stitch needle located above the spiral into a chain binding fastening the spiral element to the tape.
