Abstract
The perforating machine is provided with a perforating roll having a perforating bar and a base roll below the perforating roll which can be moved between a raised position and a retracted position. In the raised position, the base roll allows the perforating bar to perforate a web passing between the two rolls. In the retracted position, the base roll lowers the web away from the perforator roll so that a perforation is not effected. A programmer is also provided to program the motion of the base roll so as to adjust the centerline to centerline spacing of the lines of perforations in the web. The perforator roll is also driven by a transmission employing elliptical gears so that the perforator roll is accelerated prior to perforating the web and decelerated thereafter. The machine may also be used to cut the web into a series of panels rather than simply perforating the web.
