clockwise direction as viewed from the front side and rotation of rollers 64 39 66 39 and belt 62 39 in a clockwise direction as will be seen the direction of rotation of belts 62 and 62 39 is reversible to move wire 34 in either forward toward the right as viewed from the front side or rearward directions upon exiting belts 62 62 39 in the forward direction wire 34 enters opening 67 in cylindrical member 69 and extends through an axial passageway in a wire guide comprising hollow shaft 70 and tip 71 the passageway has a diameter slightly larger than that of the wire thereby controlling quite closely the axial path of the wire a number of additional wire guides all denoted by reference numeral 70 39 are conveniently stored on stub shafts not shown extending forwardly from front wall 12 each of guides 70 39 is essentially identical to guide 70 71 except that the diameter of the internal passageway is different in each guide any one of the wire guides may be selectively mounted in the operative position in a manner described later to provide the axial passageway conforming most closely to the diameter or gauge of the wire being processed upon exiting guide tip 71 wire 34 passes through aligned openings in blades 72 and 74 the structure and manner of operation of blades 72 and 74 form an important aspect of the present invention and will.
