ABSTRACT:
A power driven wire twister is suitable for twisting relatively heavy multi-strand wires. The strands are twisted by means of a chain and sprocket drive. The wire twister housing and output sprocket are suitably slotted to allow placement of the wire at the axis of rotation of the twisting sprocket. A tooth carried by the output sprocket separates the strands of the wire into two approximately equal groups prior to twisting. A large angle of contact between the chain and slotted output sprocket insures that a sufficient number of sprocket teeth are always in mesh with the chain for heavy duty continuous operation.
