ABSTRACT:
A deflection coiling attachment for a wire winding machine particularly adapted for the making of complex spring configurations employing first and second separately controllable feed means comprising a feed snubber adapted for bi-directional movement and a feed roller mechanism adapted for uni-directional operation. The two separate feeds operate in sequence. In the disclosed embodiment the work station has supported there at a deflection head for forming spring coils, a bending tool and bending anvil for forming spring bends, guide members and a cutting tool. The feed roller drive is cam operated primarily for drive of the wire during the spring coiling sequences. The bi-directional snubber feed controls wire movement for other actions such as during bending sequences.
