Abstract
An on-demand exact registration form web perforating apparatus is simple yet effective, and can operate at high speed and has a long life. A form web is moved in a predetermined path past first and second rotatable continuous circumferential perforator wheels mounted on substantially stationary axes and spaced from each other along the predetermined path and in alignment with each other along the path. First and second anvil cylinders are spaced from each other along the path for cooperation with the wheels, each cylinder having an interrupted circumference including a raised portion and a depressed portion, and a movable axis about which the cylinder rotates. The cylinders are rotated about the axes synchronously with the web movement, and the cylinders may be selectively moved toward and away from the perforator wheels from a first position in which the entire circumference of each anvil cylinder is spaced from the web and does not cooperate with a perforator wheel, to a second position in which the anvil cylinder circumferential raised portion may engage the web and cooperate with a perforator wheel to effect perforation. Typically the form web comprises a plurality of business forms.
