    Abstract: The apparatus for conveying printed products has a feeding device which conveys the printed products to a discharge end. The gripper circulatory path of the gripper conveyor moves with the receiving section past the latter. During movement through the receiving section, the grippers use their gripper mouth to grasp the printed products and convey said products further. If the receiving section is located in the central position with respect to the feeding device, the printed products are grasped centrally and conveyed further. If, by contrast, the receiving section is displaced by means of the adjustment device into a side position, the printed products are grasped eccentrically and guided further.

  • Patent number: 7478806
    Abstract: An apparatus for conveying sheets through a printing machine allows continuous monitoring of the position of a sheet with regard to a guide element over a long time period. There is provided a circulating conveyor element with grippers in which the sheet is held at a leading edge. A device for setting the position of the sheet can adjust the position with regard to a desired position. A measuring configuration measures the position and the presence of the sheet. A control device is connected to the device for setting the position and to the measuring configuration. The measuring configuration is mounted so as to circulate with the conveyor element.

  • Patent number: 7478807
    Abstract: A method for conveying a sheet includes guiding an electrically charged sheet pneumatically along a desired path, continuously detecting a charge distribution on the sheet, and reducing a positional deviation of the sheet from the desired path by actuating at least one actuating element influencing the position in dependence on the charge distribution. An apparatus for conveying a sheet includes a control device for the position of the sheet and a sensor connected to the control device for detecting an electric field present on the sheet. The method and apparatus permit the sheet to be guided with small deviations from the desired path.

  • Patent number: 7434803
    Abstract: A delivery station and a method for unblanked sheet delivery uses a delivery pull-out frame provided with front jogging stops and transverse gripper bars. The ends of the bars are fixedly attached to two respective endless loops flexible drive elements for conveying the sheets in process. The front jogging stops of the delivery pull-out frame are spaced apart to allow the passage between them of grippers of the gripper bar. The gripper bar is inclined around a transverse shaft, for lowering the level of the grippers below the level of the respective upper edges of the front jogging stops, by simultaneously opening the said grippers, in order to separate the sheet from the grippers by bringing the front edge of the sheet against the front stops.

  • Patent number: 7427064
    Abstract: A machine for processing a sheet of printing material contains a first chain conveyor having a first gripper bar for holding a leading edge of the sheet, and a second chain conveyor having a rear gripper bar for simultaneously holding a trailing end of the sheet. A processing device is assigned to the chain conveyors for processing the sheet. A distance changing device is provided for temporarily reducing a gripper distance between the two gripper bars and, consequently, producing a sheet sag required for the processing of the sheet carried out by the processing device. The distance changing device defines a first circulation path of the front gripper bar, determined by the first chain conveyor, and a second circulation path of the rear gripper bar, determined by the second chain conveyor, running locally differently from each other. The processing device can be, for example, a sheet smoother.

  • Publication number: 20080210521
    Abstract: A conveying system to be used in the printing industry, especially in mailroom technology, includes a revolvingly driven conveying member that is provided with supporting elements that are fixed to a traction rope in a stationary and optionally torsion-proof manner. The conveying member can be provided with another rope that has the same length as the traction rope, revolves substantially parallel thereto, and is used as a guide rope or second traction rope. Grippers that are disposed laterally on the belt-shaped conveying member, which is formed by ropes and supporting elements, are arranged on the supporting elements in order to grab and hold individual printed products or groups of printed products. The conveying members is deflected onto different deflection planes via guiding devices while being twisted between such deflections such that the three-dimensional position of the supporting elements and the conveyed printed products can be modified.

  • Patent number: 7334790
    Abstract: Sheets are conveyed through a rotary press with linear travel grippers. The novel conveying apparatus prevents collisions between the grippers and printing unit cylinders. The grippers are fixed to circulating links to convey a sheet through a nip between two cylinders that interact during printing. The links and the cylinders are coupled to drives that can be activated separately. In each case a collision disk is mounted on a shaft journal of at least one cylinder. A slip clutch is provided between the collision disk and the cylinder. A braking element is coupled to the grippers which, in the event of non-synchronous running with the cylinder, runs onto the collision disk and prevents the collision disk from moving.

  • Patent number: 7318587
    Abstract: The invention relates to a method of, and an apparatus for, stabilizing and positioning sheet like articles (16), in particular printed products. In order to prevent the products from buckling and fanning out, the position of an edge (20) of the product (16) counter to and/or in the conveying direction (F) is delimited by a respective trailing and/or leading delimiting element (24, 26), a receiving means (27) for the edge (20) being formed between a respective leading delimiting element (24) and a delimiting element (26) which follows the latter in the conveying direction (F). By virtue of at least one further delimiting element (28) being moved into the conveying stream (54) upstream of, or in, the starting region (S1) of a stabilizing portion (S) of the conveying section (11), the position of the edge (20) in and/or counter to the conveying direction (F) is localized such that the edge (20) passes only into the receiving means (27) and not into the intermediate region (29) between two receiving means (27).
