Method and device for tying a bundle of electrical wires

摘要

In a device for automatically looping a thread about a bundle of wires to form a continuous crocheted tying structure, a camming mechanism is provided for limiting the tying cycles to two and for adding a plurality of knotting cycles. A cutting knife and an intercept needle are reciprocatably mounted to the housing of the device and are shifted by a pneumatic cylinder under control of the camming mechanism. The knife cuts the thread after the formation of a plurality of knot loops, while the intercept needle catches the thread and holds it for the next work operation.
