    摘要： An apparatus for the removal of proof sheets from a sheet-processing machine has at least one sheet catcher provided with a gripper device. The gripper draws the sheet out of the stacking region. A lower sheet catcher is first moved into the stacking region above the sheet stack. Following a deposition of at least one proof sheet, the sheet is gripped with the gripper device, and following sheets are held back with an upper sheet catcher. Then the proof sheet is drawn out of the stacking region by moving the lower sheet catcher and the gripper device back.

    摘要： Sheets are conveyed through a printing machine with improved reliability of the suction grippers. The apparatus for conveying a sheet through a printing machine has a cylinder with grippers in a channel for holding the sheet at its leading edge, circulating grippers for holding and for transferring the sheet from the cylinder at its leading edge, and circulating, radially positionable suction grippers for holding the sheet at its trailing edge. An actuating apparatus opens and closes the grippers and controls vacuum for the suction grippers. A drive for the cylinder and circulating grippers and suction grippers. A control device switches on and off the sheet feed to the cylinder. The suction grippers can be moved in the radial direction into a rest position when the sheet feed is switched off.

    摘要： A device for conveying a sheet through a printing machine includes a cylinder, formed with a channel wherein grippers are disposed for holding the sheet at a leading edge, a chain conveyor with grippers fixed to endless chains for holding and picking up the sheet at its leading edge from the cylinder and for holding the sheet at its trailing edge, and rotating sprockets carrying the chains. An actuating device is provided for opening and closing the grippers, and a drive is provided for the cylinder and the sprockets. Gripper pads and gripper tips for the trailing-edge grippers, in opened condition of the grippers, are able to run past the cylinder. The gripper pads and tips lie underneath a path described by the sheet. The trailing-edge grippers are closable in a rotational angle region wherein the chains run off the sprockets for the cylinder.

    摘要： A method for applying powder to a printed sheet includes ejecting air flows from a nozzle bar. The air flows are set in such a way that the air flows which are ejected per meter length of the nozzle bar produce a resultant force acting on the printed sheet of from 0.5 newtons to 16 newtons. A printing press for carrying out the method is also provided.
