ABSTRACT:
A method for controlling the movement of a web of material. The web material advances in a forward direction, thus creating an unsupported loop which characterizes the festoon arrangement of the invention. Web material is advanced into the festoon depending upon the size of the festoon. Web material is withdrawn and returned to the festoon on an intermittent basis independently of the flow of material into the festoon.
