ABSTRACT:
A continuous coupling element is fashioned from an elongated synthetic resin filament or the like, which filament is bent to a zigzag or meandering configuration to provide a series of U-shaped transverse portions each having a coupling head and a pair of legs extending rearwardly therefrom. Parts of the legs of each U-shaped portion are deformed to provide tape gripping portions, respectively, which include laterally expanded, flat surfaces arranged in opposed relationship to each other. The continuous coupling element is to be anchored to a stringer tape as by bonding or fusing the tape gripping portions to the opposite surfaces of the tape.
