Trained as separating and Schleppsauger acceptance elements for removing the sheet from the sheet stack remain switched off when switching on the investor, while the speed of the printing press is raised to above a base speed and below the production speed provided for the production speed intermediate speed.
  • the decrease elements are switched on, whereupon the pressure begins after the entry of a first sheet into the printing press. Thereupon, the ramp-up from the intermediate speed to the intended production for the production speed.
  • a method for a printing machine which has independently controllable drives for the sheet feeder and for the printing press.
  • the printing press is switched on and accelerated to a basic speed. Only after reaching the basic speed of the sheet feeder is switched on.
  • the investor's two motors one of which drives the conveyor belt of the feeder table designed as a suction conveyor and one of the sheet separators, synchronize themselves with regard to the printing press or the printing unit until they both work in time. Thereafter, the suction air is turned on to the suction belt of the investor. After a certain number of revolutions of the printing unit (for example, three revolutions), the suction air is switched on the lifting sucker and the drag sucker.
  • the lifting sucker or hoists lift a printed sheet, transfer it to the one or more drag sucker and the drag suckers transport it to the conveyor belt.
  • This solution has the disadvantage that the first printed sheet is often passed obliquely or shifted to the conveyor belt. This can break the sheet and cause a restart.
  • the invention is therefore based on the development of a method for starting / restarting a sheet-fed press, which guarantees a safe and fast start of the sheet-fed printing press.
  • the object is achieved by a method having the features of the first claim.

  • a belt table 2 is shown as a suction belt table 2.1.
  • the solution according to the invention is explained here with reference to a sheet feeder 1 with a suction belt table 2.1, in which printed sheets 8, 8.1 are held by negative pressure on suction belts 26.1 equipped with holes, the solution according to the invention also being able to be realized with a sheet feeder 1 with a belt table 2, in which the printed sheets 8, 8.1 are guided in known manner by pressure rollers arranged on a bar grid against a conveyor belt 26 of the belt table 2.
  • the suction belt 2.1 a feed table 3 with front marks 4, a vibration system 5 and a Anlegzylinder 6 of a designed as an attachment printing unit printing unit 7 a sheetfed press downstream.
  • the printing unit 7 may also be the only printing unit of the sheet-fed press.
  • 8.1 sheet stack 9 is positioned on a stacking plate 10.
  • the stacking plate 10 is attached to transport means 11, which are connected to a lift, not shown.
  • the top of the sheet stack 9 is associated with a sheet separator 12.
  • the sheet separator 12 has a plurality of separating suction 13 and several transport suction 14 and trailing edge stops 15.
  • the sheet separator 12 is height adjustable by means of an actuator 16. In addition, the sheet separator 12 can be moved to format adaptation in or against a transport direction 17.
  • the sheet separator 12 in the embodiment, a the height level of the sheet pile 9 detecting scanning 18 is assigned.
  • the drive of the sheet separator 12 is effected by means of a first single drive 19, e.g. can be designed as an electric motor.
  • blasters 36 are still provided. These are for Vorlockern the sheet 8, 8.1 on the sheet stack 9 and for underblowing the sheet 8, 8.1 intended during transport.
  • side sheets 20 are arranged on the side of the printed sheet stack 9 on the side. But it is also possible to assign only the printing sheet stack 9 laterally delimiting guide elements 20.1.
  • a flap shaft 21 At the front side of the printing sheet stack 9 extends over the width of the printing sheet stack 9, a flap shaft 21. This is a Blasstange 22 downstream, the blowing direction is approximately opposite to a transport direction 17.
  • the suction belt table 2.1 consists of a drive roller 23 and a guide roller 24, between which a suction box 25 is provided, wherein the rollers 23, 24 are wrapped by at least one suction belt 26.1.
  • the suction belt 26.1 is tensioned by tension rollers 27.
  • the suction belt 26.1 is provided in a known manner with suction openings which come into engagement with suction holes provided in the suction box 25 during their movement in the transport direction 17, driven by the drive roller 23.
  • the drive roller 23 is driven by a single drive 28 of the conveyor belt 26, e.g. powered by an electric motor. With the drive roller 23 corresponding clock rollers 29 which are controlled periodically within a power stroke against the drive roller 23.
  • the suction belt 2.1 a feed table 3 is arranged downstream. From a located below the feed table 3 locking position the front marks 4 are controlled in a working position.
  • the plant table 3 downstream vibration system 5 has a sheet holding system 30 and performs a pivotal movement between the feed table 3 and the Anlegzylinder 6 of the printing unit 7 from.
  • the printing unit 7 has a drive 31.
  • This drive 31 is preferably a main wheel train of the sheet-fed printing machine connected to a main drive, which drives all printing units of the sheet-fed printing press.
