ABSTRACT:
A no touch machine trigger system which triggers the associated machine into operation without the aid of a foot switch or other external device(s) actuated by an operator. The target area of the trigger system is conical in shape so as to guide the trigger mechanism to a fiber optic sensor at the apex of the cone shaped target area. The machine is not activated until the light across the apex of the cone is interrupted by the trigger mechanism, which does not occur until the trigger mechanism is properly oriented for the machine's operation. The trigger system is placed inside the machine where the operator cannot cause an inadvertent trigger. The trigger system is ideally suited to implementation in a wire stripping device, where the trigger mechanism is a wire to be stripped. The cone shaped target area has an oblique angle so that wires of a variety of sizes may be used to trigger the wire stripping device without adjustment.
