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.
A rewinder for cyclically winding logs of bathroom tissue or kitchen toweling with a pattern repeated between each pair of adjacent lines of transverse perforation, comprising a frame having knife-carrying perforation means, winding means, phase actuation-equipped cutoff means and means for advancing a pattern-equipped extensible web along a path toward said perforation means, a detector a on said frame for sensing the position of each pattern relative to the position of the perforation means, a controller on said frame for adjusting said perforation means to insure that each perforation is between pattern positions including means for generating a perforator knife position feed back signal, and means operably associated with said controller and cutoff means for adjusting said cutoff means to stay in time with perforations to provide a preselected count of patterns in each winding cycle.
A method for cyclically producing logs of bathroom tissue or kitchen toweling with a printed pattern repeated between each pair of adjacent lines of transverse perforation, comprising
A method for cyclically producing rolls of bathroom tissue or kitchen toweling with a pattern repeated between each pair of adjacent lines of transverse perforation, comprising the steps of
A rewinder for cyclically winding logs of bathroom tissue or kitchen toweling with a pattern repeated between each pair of adjacent lines of transverse perforation, comprising a frame equipped with perforation means, winding means, cutoff means and means for advancing a pattern-equipped extensible web along a path toward said perforation means, a detector and controller on said frame for sensing the position of each pattern while generally simultaneously therewith sensing the position of said perforation means, means operably associated with said controller and perforation means for adjusting said perforation means to insure that each perforation is between pattern positions, and means operably associated with said controller and cutoff means for adjusting said cutoff means to stay in time with perforations to provide a preselected count of patterns in each winding cycle.
