Patent number: 5019206Abstract: A press apparatus is provided wherein the vacuum suction lifters, due to a swing-in movement, can be moved more quickly into the lifting position for attaching the finish-coated panel by suction and, due to the telescopic extension, can be accurately set to the statically best longitudinal positions for panels of various widths. By a positioning and drive device, rolling belt trays used according to the invention can be moved accurately at various positions into the press area in conformity with different panel widths. As a result of the construction members and measures according to the invention, the movable parts have been further reduced in weight, thereby permitting faster movements. Furthermore, this results in higher flexibility and greater operational readiness of the short-cycle installation when changing over to other panel widths.Type: GrantFiled: June 28, 1989Date of Patent: May 28, 1991Assignee: Maschinenfabrik J.

Patent number: RE33602Abstract: The upper panel of a tailgate assembly is moved in a downward and rearward convexly curved path between an upward and forward position and a rearward and lowered position and the lower panel is rotated forwardly and rearwardly with respect to the upper panel. Linkages are included in the tailgate assembly to provide this movement. A lower surface of the fixed panel may have an upwardly curved lower surface which imparts a forward direction of movement to refuse which is packed against it. The upper panel may have a curved forward surface in close proximity to a rearward surface of the fixed panel. During movement of the upper panel, the rearward surface of the fixed panel removes refuse from the curved forward surface. The upper panel is tilted as it moves and during its upward movement the lower portion of the upper panel is tilted forwardly. This imparts a forward movement to refuse which is moved through the opening into the storage body.Type: GrantFiled: July 24, 1987Date of Patent: June 4, 1991Assignee: Sargent Industries, Inc.Inventor: Fred T.
