20110069921 | BEARING FOR A VACUUM ROLLER THAT CAN BE SUBJECTED TO SUCTION AIR FROM BOTH SIDES - A bearing structure has a frame, a vacuum roller mounted on the frame, operable to be axially subjected to suction air from both sides, a first bearing arranged in a first bearing housing and a second bearing arranged in a second bearing housing, and a first bearing journal disposed on a first end of the roller, and a second bearing journal disposed on a second end of the roller. The roller is mounted in the first bearing so that there is a substantially constant clearance between a first front face of the roller. The roller is mounted in the second bearing so that there is a substantially constant separation between a second front face of the roller. The second bearing housing is arranged such that the second bearing housing is axially displaceable relative to the frame. | 03-24-2011 |
20100201060 | APPARATUS AND METHOD FOR DRAWING IN FLAT MATERIAL PIECES AND IN-REGISTER TRANSPORTATION OF THE FLAT MATERIAL PIECES - A device for pulling in flat-stock pieces and precisely-aligned transporting of the flat-stock pieces at a work station of a machine for processing the flat-stock pieces has a gripper apparatus that grabs a forward edge of a piece of flat stock and accelerates the flat-stock piece, and a sheet pick-up roller that picks up the accelerated piece of flat stock from the gripper apparatus, whereby the sheet pick-up roller has a roller gripper effective at a circumference thereof for grabbing the accelerated piece of flat stock. The roller gripper can move between a closed position in which the piece of flat stock is held fast and an open position in which the piece of flat stock is released. Suction holes operable to be charged with intake air are disposed in a part of a circumference of the sheet pick-up roller following in a direction of rotation behind the roller gripper. | 08-12-2010 |
20090092476 | METHOD AND APPARATUS FOR ALLOCATING DIFFERENT AUXILIARY MATERIALS TO BE PICKED UP BY A PALLETIZING ROBOT - A device is described for providing different auxiliary materials by a palleting robot for palleting objects at a palleting site. A palleting cell has storage sites, and the device is provided with a single supply site. A palleting cell is supplied with the auxiliary materials. The storage sites are arranged at a side of the supply site sequentially in a direction of transportation so that a gap of the auxiliary materials at one of the storage sites is closed by the auxiliary materials that are located at one of the storage sites and/or the supply site in the direction of transportation. | 04-09-2009 |
20080242526 | DEVICE FOR THE MEMORIZING OF A NUMBER OF PRE-CREASING IN A MATERIAL COAT - A device to stamp a number of creases into a material layer is provided, the device comprising a main roller body non-rotationally arranged on a rotating shaft and a number of holding elements sunk into the main roller body that serve to position and/or affix a first foil having a first creasing ridge on the circumferential surface of the main roller body, which is characterized in that a holding device is provided that can be angularly rotated relative to the longitudinal axis of the rotating shaft and that is configured to position and/or affix at least one additional second foil having a second creasing ridge. | 10-02-2008 |
