Patent number: 9021849Abstract: The present invention is a shrinker stretcher machine that uses four distinct and separate tool cartridges to perform both shrinking and stretching operations by simply removing, rotating each tool cartridge 180 degrees, and reattaching it in its designated position. Each tool cartridge removably carries a jaw that can be removed and securely replaced with either a shrinker or stretcher jaw to accommodate the operation being performed. Each tool cartridges and jaw is firmly held in place by magnets and interlocking keyed surfaces to properly align and hold the tool cartridges and jaws.Type: GrantFiled: September 26, 2011Date of Patent: May 5, 2015Inventor: Christopher J. Rusch

Patent number: 7963223Abstract: An apparatus and method for bending a printing plate is disclosed. A bending machine, in particular for the bending of printing plates which are used in printing machines, includes a pressure pad, which exerts the required clamping force on the printing plate during the bending operation, and which is movable in relation to a holding-down plate, so that a uniform clamping force acts on the printing plate over the entire length of the pressure pad.Type: GrantFiled: September 21, 2006Date of Patent: June 21, 2011Assignee: MAN Roland Druckmashinen AGInventors: Georg Schmid, Thomas Kling, Michael Scholz

Gripping apparatus for gripping and holding elongated workpieces, in particular for bending machines
Patent number: 7891227Abstract: A gripping apparatus for gripping elongated workpieces comprises a housing, carrying two pivotable gripping jaws which are movable between opened and closed positions, as well as a guiding body, in which the housing is displaceably supported. A rod having a control element which is located between both gripping jaws and is displaceable between a position retracted into the gripping jaws and so as to spread them apart, and an opposite position, where the gripping jaws are converged. The control element engages the housing and, during a further movement in the retraction direction moves the housing.Type: GrantFiled: March 13, 2008Date of Patent: February 22, 2011Assignee: WAFIOS AktiengesellschaftInventors: Joerg Moeck, Stefan Holder, Paul Frick -
Patent number: 6276187Abstract: A clamping device including a housing having a base portion slideably mounted to be positionable along the width of a carriage, the carriage being slideably mounted to be positionable along the length of a guide track. The housing includes a clamping jaw pivotally mounted therein and activatable by a hydraulic cylinder. The carriage is designed to interlock with the base portion of the housing and with the guide track upon activation of the hydraulic cylinder.Type: GrantFiled: August 27, 1998Date of Patent: August 21, 2001Inventor: Timothy A. Hutchinson

Patent number: 4606213Abstract: A tool for producing bends or steps in curved surfaces has an upper and a lower tool part arranged to work towards one another when in operation. The tool part surfaces conform in shape with the curved surface in which one or more bends are to be formed. The tool part surfaces are made as form tools resiliently mounted and guided in the upper and lower tool parts. The form tools also identify in shape with the original curved surface. The inventive tool is suitably arranged in a press.Type: GrantFiled: July 30, 1984Date of Patent: August 19, 1986Assignee: AB VolvoInventor: Bengt G. Persson
