The cross cutter is often considered to be the heart of a sheeter. The cross cutter or just knife cuts the paper or board web transversally to the required sheet length. The unit consists of two rotating knife cylinders across the full web width, with a blade mounted slightly oblique on each cylinder. The top and the bottom cylinder are rotating against each other. A precise, accurate cross cut is crucial for the overall cut quality. BW Papersystems combines decades of experience in the cutting of paper and board, drawing on the legendary knife technologies from Marquip, E.C.H. Will, Jagenberg sheeters and bielomatik.
Cutting trials on a BW Papersystems lab sheeter help to establish the best knife geometry for specific materials to be cut.
