ABSTRACT:
A method and apparatus for producing a roll or log of bathroom tissue or kitchen toweling with a pattern being repeated between each pair of transverse perforations wherein an extensible web having a pattern thereon repeated at equally longitudinally spaced position is advanced along a path toward a rewinder having a knife-equipped perforator and a cutoff mechanism. A detector senses the position of each pattern and also sensed is the position of the perforation knife with the positions being reported to a controller. The perforation knife is adjusted to insure that each perforation is between pattern positions and the cutoff mechanism is adjusted to stay in time with the transverse lines of perforations to provide a selected count of patterns in each winding cycle.
