Abstract
A bursting machine is provided for separating discrete sheets from a continuous strip of sheets having uniformly spaced perforation lines across the width of the strip. A gauging device with numerical increments in the form of a linear scale is manually compared to the length of the discrete sheets to provide a predetermined number corresponding to a pulse count for entering into a control device through a manually settable device. The control device in turn is operatively connected to an electronic pulse counter. When the leading edge of the strip advances a predetermined increment after passing through a sensing device located downstream in the path of travel with respect to a first pair of feed rollers, a pulse generator attached to the driven first feed roller is actuated to generate pulses for counting to reach the preset number in the pulse counter. When the preset number is reached, a second pair of feed rollers is stopped through disablement of an electromagnetic clutch and enablement of a brake while the leading sheet is continued to be conveyed downstream by the first pair of feed rollers to effect a burst.
