Abstract: 1,179,799. Bending cutters; attaching electrical components to printed circuits INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1967 [26 Oct., 1966], No. 44713/67. Headings B3A and B3W. In apparatus for forming a wire element for a printed circuit and positioning it on a substrate S, a length of wire fed on to a mandrel 40 and retained by vacuum means on a transfer member 38 is sheared by a cutter 42 surrounding the member 38 which co-operates with the mandrel to bend the wire into a bridge (E), Fig. 10 (not shown); the member 38 continues downwardly, setting the bridge firmly on lands (L) on the substrate and then ejecting it by means of a jet of air. A frame 50 mounted on a longitudinally and transversely adjustable base supports the apparatus through a rotatable head 34 which can be locked in position by means of a spring bolt 52. A drive shaft 54 carries cams 56, 58, 60, 62. Cam 62, through cam follower 74, actuates a slide 75 and a pawl- and-ratchet assembly 72, 70 drivingly connected with a roller 66 to feed wire from a dispenser 64 through rollers 66, 68 to the head 34 until it abuts the far side of the recess in which the cutter reciprocates and then overdrives it. A spring-urged pawl 73 prevents reverse rotation of ratchet 70. Cam 60, through cam follower 94 and spring-return levers 93, 92 actuates movement of the cutter 42. Engagement of an abutment 99 on the cutter as it descends with a push-rod 98 swings the mandrel 40 out of the forming position. Cam 58 actuates movement of member 38 relative to the cutter 42 through cam follower 82 and spring-return levers 78, 80. The lever 78 is urged against a flange 84 on the member 38 by a spring 86. The formed bridge (E), Fig. 10, is temporarily located on the substrate by means of a flux and then heated to fuse the ends of the bridge to the lands (L).
