Apparatus and method for securing end turns of coil springs to a border wire

摘要

The apparatus has an indexable carriage adapted to move the coil springs and the border wire along a path. A wire cutter disposed adjacent the path has an inner member with an axial hole adapted to receive the wire and a tubular outer member receiving the inner member and movable relative to the inner member. The outer member has a cutting edge. An actuator is operatively connected to one of the inner and outer members to provide a relative rotation between the inner and outer members. That relative rotation results in the wire being sheared by the cutting edge to provide a length of wire. A wire wrapping mechanism disposed adjacent the path receives the length of wire and wraps the length of wire around an end turn of a coil spring and a border wire.
