ABSTRACT:
An illustrative embodiment of the invention produces comb-like bookbinding wire stock in a manner that significantly reduces wire breakage during manufacture as well as unequally stressing or stretching or marring the surface finish of the wire from which the stock is formed. An indexing unit drives a pair of forming arm members that pivot under the control of a cam surface. These members align and wind a wire strand onto pins that protrude radially from a pair of parallel, axially spaced rings. Operation of a reciprocating side pusher and center pusher shaft press the wire strand onto the adjacent pins and a wire flattening roller presses one side of the partially formed stock against the adjacent pin surfaces to produce the "back" for the comb-like stock. A rotating pinch roll "sets" the fingertip portions of the tines on the stock. Because the plane surfaces of the circular rings are parallel, substantially less time is required to set up the machinery that characterizes the invention and undertake a production run than that which characterized prior art devices.
