Patent number: 5505994Abstract: Fabric-handling equipment which removes a fabric web from a stack of such webs or from a supporting surface, dries ink printed on a fabric, and removes a porous fabric held onto a surface by a vacuum. To remove a fabric web from a surface, like a stack of such webs, a device places needles partially into the web. Since the needles extend into the fabric less than about nine tenths of the fabric's thickness, they can only attach to the upper surface of a single web. The needles, after insertion into the web, separate from each other to effectuate a firm connection. When the device raises, it can only lift a single web. When a fabric web receives printing, touching it with a heated block having a Teflon surface cures the ink. This permits its subsequent printing or collecting and stacking. A fabric web may adhere to a supporting surface through suction.Type: GrantFiled: March 16, 1994Date of Patent: April 9, 1996Assignee: QST Industries, Inc.Inventor: Warren N. Crawford

Patent number: 5076754Abstract: An apparatus for forming stacks from consecutively fed, flat workpieces, preferably bags, comprises a ram, which is movable up and down and serves to force the workpieces from a plane of conveyance onto a stacking plate or onto a stack formed on said stacking plate. The stacking plate is adapted to be lifted and to be lowered to an extent depending on the increasing height of the stack. In order to ensure that the ram will exert an approximately constant force on each workpiece as it is stacked, the stacking plate is adapted to be lowered against the action of a force exerted by a brake.Type: GrantFiled: July 11, 1990Date of Patent: December 31, 1991Assignee: Windmoller & HolscherInventors: Wilfried Ebmeyer, Gunter Mattiebe

Patent number: 5062340Abstract: Apparatus for cutting a continuous web into precise length sheets and precisely stacking the sheets, relative to each other, includes first and second moving endless belt tables for advancing the web, a sheet orientation table and a stacking table. A vacuum holds the web firmly, without tension, against the respective belts. A shearing device is disposed between the first and second endless belts. Web, detectors positioned along the line of travel of the web, detect printed or colored lines on the web to obtain accurately cut sheets. Individually driven and positioned sheet grippers grasp the cut sheet positioning each sheet under dual hole punching devices which punch precisely positioned holes in each sheet. A pair of aligning pins on a sheet stacking bed are used as guides for orienting the sheets in interleave configuration. Each sheet is secured to its adjacent sheet to maintain sheet orientation.Type: GrantFiled: June 21, 1990Date of Patent: November 5, 1991Inventor: Richard Greven

Patent number: 5039078Abstract: Apparatus for the seriatim separation and feeding of garment parts from a shingled stack of the parts to a predetermined destination. Comprising the apparatus is a movable hold down mechanism for engaging the trailing edge of the second part in the stack and a picker head for engaging the leading edge of the first part in the shingled stack and removing it from the stack. Mechanisms are provided for accurately determining the location of the trailing edge of the second part in the stack and moving the hold down mechanism into position to accurately engage the trailing edge of the second part in the stack. Following separation, the separated part is transferred to a second location at which the head is withdrawn from the transferred part.Type: GrantFiled: October 2, 1989Date of Patent: August 13, 1991Assignee: Levi Strauss & Co.Inventors: Hubert Blessing, Gene Croyle

Patent number: 4899983Abstract: A valve plug having a valve plug housing shaped to fit in a bonnet cylinder of steam control valves has a pressure seal ring groove for holding a pressure seal ring therein. The pressure seal ring groove has a pair of walls and a bottom surface end and antiwedging relief groove formed in one wall of the pressure seal ring groove adjacent the bottom surface thereof to prevent the wedging of a pressure seal ring between a valve plug and a bonnet cylinder bore wall. The pressure seal ring wears a step in the contact surface to allow the wedging which can otherwise prevent the valve from closing as required for turbine overspeed protection. The valve plug housing pressure seal ring groove can be annular groove having an annular pressure seal ring therein and the relief groove can be annular groove formed in one wall of the pressure seal ring groove adjacent the pressure seal ring along the seal ring contact surface of the pressure seal ring.Type: GrantFiled: January 18, 1989Date of Patent: February 13, 1990Assignee: Westinghouse Electric Corp.Inventors: David B. Berrong, Thomas L. Schuchart

Patent number: 4838536Abstract: A fabric picking and transferring device for transferring one or more top fabric plies from a stack of such plies. The device comprises a support body having a fabric engaging end. The housing is displaced toward the stack to position the fabric engaging end on an uppermost ply of the stack. At least two picking needles are supported by the body and each has a pointed engaging end portion. The needles are disposed in opposed offset facing relationship and at a shallow angle with respect to the plane of the uppermost ply, with the pointed engaging end portion retracted inside the fabric engaging end of the body. An actuating mechanism is provided for moving the fabric engaging end of the needles a predetermined distance outwardly of the fabric engaging end with the fabric engaging ends crossing one another, and wherein the needles will penetrate in each of the one or more uppermost fabric plies.Type: GrantFiled: October 13, 1987Date of Patent: June 13, 1989Inventor: Nabil Kamal
