ABSTRACT:
The invention is a method and apparatus for producing slit pieces of finished corrugated board from respective paper liners and at least one fluting using a corrugated line having at least a single facer, a double backer and a slitter, while minimizing or substantially eliminating waste resulting from the misalignment of the respective liners, flutings, single face web and corrugated product. The method comprises aligning the measured positions of a liner and fluting relative to one another and relative to the single facer prior to their respective entry into the single facer and in response to a signal representative of the relative measured positions, aligning the measured positions of a second paper liner and the single face web relative to one another and relative to the double backer prior to their entry into the double backer and in response to a signal representative of the measured positions by passing the single face web over a vacuum tensioning means that tensions the single face web, moving the vacuum tensioning means in order to concurrently move the tensioned single face web and align it with the second liner to accurately superimpose the second liner and the single face web upon one another, and aligning a measured position of the corrugated board with respect to the slitter in response to a signal representative of the measured position to minimize the error in alignment between the corrugated board and the slitter thereby producing slit cardboard with a minimum of waste.
