ABSTRACT:
A device for cutting a web into a plurality of longitudinal sections, comprising slitters, a center drum and supporting arms for rewind rolls formed of adjacent slitted web sections and located at opposite sides of the center drum. The arms are attached to sliding carriages movable along guide beams in a cross-web direction and the slitters are attached to the sliding carriages and move with them when the slitting width is set, so that the slitters and the supporting arms are automatically correctly positioned with respect to each other in a cross-web direction. The supporting arms are journalled at the rolls and at the sliding carriages and are free to move away from the center drum without affecting the position of the sliding carriages which are kept stationary during cutting and rewinding operations.
