  • Patent number: 8123221
    Abstract: 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.

  • Publication number: 20110069921
    Abstract: 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.

  • Publication number: 20090092476
    Abstract: 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.

  • Patent number: 6949059
    Abstract: A device used to separate and discard a skeleton formed when a blank is cut into the pattern of a folding carton, envelope, or other desired shape is provided. The device includes first and second separating cylinders. The second separating cylinder includes at least one protrusion extending from the surface thereof, and also has at least one recess formed therein. The protrusions are used to couple the skeleton to the second cylinder. The device further includes a stripping plate having a leading edge positioned near the second cylinder. At least one stripping finger extends from the edge of the stripping plate and within the recess of the second cylinder. The stripping finger is thereby positioned between the second cylinder and the skeleton as the second cylinder rotates toward the stripping finger. The stripping finger operates to disengage the skeleton from the protrusions, thereby stripping the skeleton from the second cylinder.

  • Patent number: 6926653
    Abstract: A device for separating and stripping waste material from a blank during a carton or envelope manufacturing process is provided. The device includes first and second separating cylinders. At least one pin and sleeve assembly is coupled to the second separating cylinder, and includes a pin having a sleeve slidably coupled thereto. A tube or hollow bar is coupled to the separating cylinder, and has at least one aperture therein generally aligned with the pin and sleeve assembly. In separating the waste material from the blank, the pin couples the waste material to the second separating cylinder. A fluid such as compressed air is forced into the tube and directed through the aperture to slide the sleeve from a retracted position in which the pin is exposed to an extended position in which the pin is concealed, whereby the waste material is forcibly removed from the pin.

  • Publication number: 20030029767
    Abstract: An envelope, bag or other mailing device for preventing the shifting of an item located within the envelope and a method for making the same is provided. The envelope includes a front panel, a back panel and at least one protrusion. The back panel is coupled to the front panel to form an interior portion formed between opposed interior surfaces of the front and back panels. The protrusion is coupled to one of the opposed interior surfaces and extends into the interior portion of the envelope. In another embodiment, a second protrusion is coupled to the other side of opposed interior surfaces and extends into the interior portion of the envelope. The protrusions are adapted tp associate with one another to protect items contained within the envelope from external forces and prevent the item from moving around within the interior portion of the envelope.
