发明名称 THE METHOD AND APPARATUS FOR SLITTING BROKE ROLLS
摘要 This invention presents a method by which the broke roll, composed of paper or board web, is stripped by slitting and an apparatus which applies the method. The solutions of prior art all have a problem which is the uncertain loosening of web layers. The broke roll is stripped by cutting gradually by the means of shuttling cutting movements either by a ploughing or rotating blade in substantially the direction parallel with the axis of the reel (1), the ploughing is following after the freely rotating cutting blade in the cutting movement so that the ploughing blade (7) is already during the same cutting movement contributing in loosening cut web layers cut by the same movement.
