ZIPPER FASTENERS, SLIDERS THEREFOR, METHODS AND APPARATUS FOR APPLYING ZIPPER FASTENERS TO SUBSTRATES

摘要

The slider (10) is shaped to have an internal cavity (80) above its profile-separating plough (70). The cavity (80) receives a portion (86) of an end stomp (50) of the zipper (24) so that, when the slider is at the limit of its zipper- closing movement, no gap is left between the slider (10) and the end stomp (50). To achieve this, the end surface of the end stomp is formed obliquely to the length of the zipper (24) and provides a triangular portion (86) of the stomp which is received in the cavity (80). Also disclosed are methods of forming the end stomp, apparatus therefor and various different shapes of end stomp achieving the same objective.
