ABSTRACT:
An elongated stringer tape is fed along a path extending substantially tangentially of a die wheel carrying in its circumferential groove a formed continuous coupling element of a zigzag or helical coil configuration composed of thermally fusible material. The coupling element is held at an elevated temperature by the die wheel. One of the longitudinal edges of the stringer tape becomes received between the shanks of the coupling element as the latter is gradually released from within the die wheel groove, and while the coupling element is partly caught in the groove and is therefore still hot, its shanks are fused to the stringer tape under application of heat and pressure.
