A modular rotary anvil for an ultrasonic welding machine for producing flat cable. The anvil comprises interchangable knurled 160, protrusion 162 or cutting (172 Fig. 9b) inserts, bracket inserts 164, 166 and end segments 168, 170 allowing anvil assembly according to cable configuration desired. The cable (Fig. 7) comprises upper (120) and lower (130) insulation sandwiching intermediate parallel conductors (140) and joined by parallel welded seams between adjacent conductors (150) having a textured, e.g. knurled, surface and smooth or less rough seams (115) at the cable edge. Edge seams may comprise a textured zone adjacent a conductor and a smooth zone adjacent the edge. Texturing reduces contact area when the cable contacts itself, reducing friction and torque and the smooth edge reduces noise when used in an airbag to steering wheel clockspring. |
