Abstract
A method and apparatus for winding strip material is described in which strip which has partially severed scrap edge portions still frangibly attached thereto, is wound on to a coil or mandrel so that the cut edges of the strip are aligned. The strip passes past trimming knives which partially sever the edge portion and sensors measure the lateral position T of the knife and the lateral position E of the uncut edge of the edge portion adjacent to the knife position A. The scrap width T--E is then recorded. As the strip is about to be wound on to the coil at position B the lateral position R of uncut edge of scrap portion is sensed by a sensor. The appropriate scrap width is then determined by reference to the recorded scrap width and the strip travel between points A and B which is determined from a tachometer attached to a roll over which the strip passes. The actual position of the cut edge of the strip at position B is determined and the axial position of the coil adjusted so that the cut edge of the strip on the coil is aligned.
