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.
