Abstract

781,782. Photo-electric control system. BRITISH DRIVER-HARRIS CO., Ltd. (Driver-Harris Co.). Dec. 6, 1954, No. 35230/54. Class 40 (3). [Also in Group XXII] A machine for making helical wire coils, e.g. electric resistance heater elements, by winding wire on a rotating mandrel (see Group XXII), has means for cutting off predetermined lengths of the coil 20 as it advances comprising a fixed blade 31 mounted on the base 82 and a movable blade 30 horizontally slidable on the base 82; the blade 30 is withdrawn by a spring 84 and the cutting stroke is effected by an electromagnet 78 controlled by a photo-electric mechanism 79 adjustably positionable along the base 82 and responding to the forward tip of the advancing coil. The electromagnet also operates a trap door to allow escape of the cut length.
