Abstract
An automatic slitter scorer apparatus is disclosed for slitting and scoring a corrugated paperboard web. The apparatus includes an upper pair of slitter shafts and an upper pair of scorer shafts, as well as a lower pair of slitter shafts and a lower pair of scorer shafts thereby defining two web paths through the apparatus. The web paths are used alternately. All of said shafts are selectively rotated by means of a single motor at one end of the apparatus. A set of trim chutes is provided for each pair of slitter shafts and is located downstream therefrom.
