EENDELIGE VASTBINDBAND VAN KUNSTHARS MATERIAAL.

摘要

A one-piece tie of plastics material for tying around a bundle of cables and the like comprises a flexible strap having transverse serrations on one side for locking with transverse teeth under the influence of a wedging portion which is formed on the strap between the serrated portion thereof and an apertured head at one end of the strap. Firstly the free end of the strap is drawn completely through the aperture to place the wedge portion within the aperture with a portion of the surface of the strap opposite the wedge portion resting on an inclined surface formed on the end wall of the head adjacent the strap. Then the strap is looped around a bundle and passed back through the head for the strap serrations to ride past the transverse locking teeth, these teeth preventing subsequent withdrawal of the strap and any tension in the strap in the withdrawal direction then serving to draw the wedge portion over the inclined surface to wedge the strap against an opposite end wall of the head. The transverse teeth are provided in one embodiment on the wedge portion and in another embodiment on the opposite end wall of the head, the serrations being provided in each case on the appropriate side of the strap.
