DEVICE FOR CUTTING THROUGH A STRIP OF MATERIAL

摘要

In machines for winding continuous strips of material (4), in particular paper or carton, devices already exist for cutting through the strip of material on the support or backing roller (1), such devices having a cutter which can be placed against the material in the region in which the material is wrapped round the roller and which can be moved transversally to the direction of motion of the material. In order to enable the strip of material (4) to be cut through reliably when the roller is changed, using a device of simple design, the invention uses as the cutter a wheel (19) which has a sharp cutting edge and can be pressed by spring action against the roller (1).
