[origin: ES8703324A1] The lower cutter of an apparatus for longitudinally slitting a continuous web is mounted for axial displacement along its support shaft to some desired position by the provision of one or more axial first slots provided in the outer periphery of the shaft, a fitting received in each slot underlying the cutter and fastened thereto, and roller bearings between and in contact with the undersurface of the fitting and the bottom of each first slot. One or more second slots are provided in the shaft periphery each receiving a pressure bar bearing against the undersurface of the cutter, and an expandable tube or pillow between the pressure bar and the bottom of the second slot is expanded for fixing the lower cutter in place after axial displacement.
