Abstract: The rotary die cutter includes a frame, having rails and vertical post walls, and a cylinder supported by the vertical post walls at a first position. There is a polyurethane tube affixed to and extended over the cylinder. First and second rings are affixed to the ends of the cylinder for fixing a position of the polyurethane tube. A pair of bearing holders at each end of the cylinder vertically lift the cylinder from a first position to a second position. The bearing holders are engaged to lifting screws driven by a motor. A pair of sliding plates at each end of the cylinder axially or horizontally shift the cylinder when lifted from the first position to a second position. The sliding plates are engaged to a screw driven by a motor for horizontal movement. The cylinder is rotated by a pulley assembly attached to the bearing holders.

Abstract: System for fixing rotary die cutters in die cutting machines for cutting laminar material includes a fixing means between the die (1) and a die-holder surface or cylinder (2) around which the die (1) is arranged, wherein the a fixing element include a plurality of bolts (3) actuated by an actuator (5) housed inside a hollow body (8) fixed to the die-holder cylinder (2) in order to provide for a rapid fixing of the rotary die to the die-holder cylinder.
