Abstract

To permit rapid axial relocation of cutter rollers or cutter wheels (2, 3; 11; 42; 78, 121) on supporting shafts (6, 7; 70, 71; 100), the cutter rollers are located on respective positioning or carrier rings (12, 41, 74, 75; 102, 120 130) surrounding the respective shafts, and are axially clamped in position by a rotatable operating ring (13, 22, 28, 40, 52, 88, 89; 107, 126, 138), rotatable about said positioning ring. The operating ring is rotatable, for example by being operator-accessible, at any circumferential position of the shaft, a hydraulically operated compression sleeve, or the like, so that the axial position of the cutter roller or wheel can be changed on the shaft regardless of the circumferential position of the shaft when it comes to rest after having cut a web into a ribbon, the width of which is to be changed.
