Abstract: A flying shear for use in a wire cutting-off machine has a cutter head reciprocated along an axis parallel to the path of wire feed. A knife equipped cutoff slide carried by the head moves perpendicular to the path of wire feed and, in cooperation with a cutoff bushing carried by the head, cuts the wire while the head moves in the same direction as the wire to produce a clean cut with little or no marring of the wire surface. The head and the slide are driven by a common drive mechanism, using a single eccentrically driven lever, located entirely above the cutoff bushing to minimize the possibility of its becoming fouled by metal particles and other debris at the cutting zone.

Abstract: The disclosed wire spooler is adapted for use in winding wire onto a spool and may be used with various kinds of spools, including the type having at least one tapered end flange, so that the traversing guide, which guides the wire onto the spool during the winding, has to move with strokes of increasing length as the spool fills with wire. The necessary increases in the traversing guide strokes are brought about by a means establishing end limits at each of which the direction of movement of the traversing guide is reversed, and by a means for widening such end limits as the total rotation of the spool increases. A pulse generator and a pair of interconnected units, each including a counter, a reference number store and a comparator, operating on a reversing mechanism, are specifically disclosed as the spool rotation measuring means, the end limit establishing means and end limit widening means.
