摘要： Apparatus for automatically cutting sections of measured length from a coil of an elongated strip which has a rotatable mounting device for the coil, a feed and straightener driven at a constant speed for pulling the strip from the coil, a hump table, a speed control unit with a pair of pinch rolls, a shears, and a device for generating a first signal when the leading edge of the trip has been transported past the shears by a distance equal to the length of the measured section for breaking the pinch rolls to stop movement of the strip at the shears and for actuating the shears, said device also generating a second signal when the leading edge of the strip has been transported past the shears by a shorter distance than the measured length of the section for actuating a pneumatic cylinder to drive the pinch rolls toward each other and grip the strip, the lower pinch roll being driven by a constant speed motor at a cicumferential speed less than the speed of the strip from the feeder, thus producing a hump between the feeder and pinch rolls.
