ABSTRACT:
A winding and forming tool attachable to a winding machine spindle shaft for reciprocating movement along and rotational movement about a longitudinal axis thereof includes an elongated winding spindle having generally radially extending slots therethrough located at longitudinally spaced apart locations along the winding spindle, and a plurality of forming racks are provided, each of the forming racks being slidably disposed within one of the generally radially extending slots. A rotatable spline shaft is at least partially disposed within the winding spindle for engaging the forming racks in a manner causing sliding movement of the forming racks along the slots to extend and retract them relative to an external surface of the winding spindle. A wire is guided internally through the winding spindle from one end thereof to an aperture in a radially facing external surface of the winding spindle. In one embodiment, the aperture is defined by a wire access recess insert and an adjacent portion of the winding spindle. The insert is removably attached to the winding spindle within a wire access recess which provides access to a cavity within the winding spindle.
