  • Patent number: 4065102
    Abstract: The method of removing printing press rollers or cylinders, and a removal mechanism for use therein in extracting relatively heavy printing press rollers from very restricted and confined locations.The method comprises affixing to the frame of the press a pair of removal mechanisms, one at each end of the press. Each such mechanism comprises a mounting bracket including clamping means, a winch and an extension having an opening through which the winch line extends. The extension rests against the topmost rollers and the line is extended into the center of the press to be wrapped about the respective end of the roller to be removed. Simultaneous operation of such winches causes the roller to be lifted from its bearings or journal, thereafter to be lowered by means of the winches for manual removal.
