Abstract
An arrangement for and method of operation for threading strand-like material such as wire or tubing around a grooved type, rotatable block assembly wherein tension is needed to pull the material through a reduction die, includes a plate mounted on the same shaft as the block. This plate supports three devices used in a time sequence relationship in said threading operation for the drawing process: a gripper arm for grasping the pointed end and introducing it into the groove; a shear for severing the pointed end; and a deflector mechanism for guiding the material away from the block assembly. Clutch assemblies are selectively operated to place the plate into and out of engagement with the drawing block for the plate's rotation therewith and it's non-rotation.
