ABSTRACT:
An on-demand exact registration form web perforating method is simple yet effective, and can operate at high speed and a long life. A form web is moved in a predetermined path past first and second rotatable continuous circumferential perforator wheels mounted on stationary axes and spaced from and in alignment with each other along the path. First and second anvil cylinders are spaced along the path for cooperation with the wheels, each cylinder having an interrupted circumference including a raised portion and a depressed portion, and an axis of rotation. 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. The web may comprise a plurality of business forms each having a length x along the path, and the perforator wheels each have a circumferential point closest to the anvil cylinder, the circumferential points spaced from each other along the predetermined path a distance yx, where y has a positive whole number. The raised portion of each of the anvil cylinders and an imaginary continuation of it over the depressed portion has a circumference of 2x.
