Abstract
Continuous coupling elements, e.g. coils of synthetic-resin monofilament, preferably in an interconnected state, are heated to a thermofixing temperature and, with the aid of additional ultrasonic energy and pressure, have upper shanks of each coupling member deformed to provide recesses adapted to receive the stitches for attachment of the coupling elements to a support tape.
