Abstract

The twisting apparatus comprises a transfer mechanism for transferring a formed wire spring to a working station and a pair of twisting units disposed on the opposite sides of the working station. Each unit comprises a mechanism for clamping the formed wire spring and a mechanism for twisting the formed wire spring while it is clamped between the clamping mechanisms. These mechanisms are actuated by pneumatic actuators. By varying the strokes of the racks of the respective units the twisting angle can be varied. The twisting units are also adjustable to vary the twisted portions of the formed wire spring.
