  • Patent number: 5018417
    Abstract: The graphic tape slicer comprises a frame having a feed guide at the rear end for receiving the graphic tape from a roll. A cutting blade is mounted in the center of the frame on a traveling blade holder that engages a threaded rod. Rollers through which the tape is extracted are mounted on the front of the frame. The extraction rollers are joined by a pulley arrangement to the threaded rod. When the graphic tape is extracted from the slicer, the front drive rollers rotate which, through the action of the pulleys, causes the threaded rod to rotate. This causes the blade to move along the threads of the threaded rod. This movement effects the cutting blade to move across the width of the graphic tape causing a resulting length of graphic tape being cut at an oblique angle. By disengaging the pulley arrangement, the blade can be positioned in a fixed location along the length of the threaded rod which will result in a straight cut along the length of the graphic tape.
