- the sheet brake 5 may also contain suction rings and / or transverse tension elements or individually driven brake elements.
- the braking stations of the sheet brake 5 are designed to be axially displaceable, so that the braking bands 9 of the braking stations can be positioned independently of one another along the machine width. Depending on the sheet format to be processed, the brake bands 9 are adjusted over the sheet width. Unnecessary braking stations can be placed outside the sheet format and / or disabled.
- the axial displacement of the individual braking stations can be done manually or preferably automated. For an automated axial adjustment of the brake bands 9, a motor is provided or each brake station is associated with a motor.

- Fig. 3a shows an embodiment of the air control of the brake station of the sheet brake 5 by an oscillating moving rotary valve.
- the drive of the rotary valve is preferably carried out by a servo motor. Via the rotary valve, either suction air is supplied via a suction air connection 1 1 or blown air via a blown air connection 12 to the air duct 8, not shown, which thus rests on the suction belt, also not shown. In the illustrated position of the rotary valve suction air is applied to the brake station. At the same time, the pneumatic connection to the blown air connection 12 is blocked.
- the oscillating movement of the rotary valve allows a particularly fast switching between the ventilation.
- the rotary valve can also be driven in rotation.
- FIG. 3b shows the braking station from FIG.
- a rotary valve located in another position.
- the pneumatic connection is blocked to the suction air connection 1 1 and the pneumatic connection to the blown air connection 12 is opened.
- the control of the rotary valve in this illustrated embodiment is as follows: During the acceleration of the suction belt, blowing air is applied. The in this time the brake element passing arc section can be printed. In the following areas, suction air can then be added to the order when a pressure-free section is contacted, or remain switched off. Thus, the pressure range can be at least partially extended to the potential contact area with the suction belt. Preferably, a connection of suction air always takes place only when the suction belt has reached machine speed.
- the suction air is job-related or print-image appropriate, especially motivational, fed to the suction belt.
- the blowing air effect occurs when printed zones are present in the effective range of the suction belt.
- smearing is avoided by the action of blowing air.
- an order-related reduction of the total pressure-free area required in the print image or motif is made possible. Continuously pressure-free corridors are continuing education and in particular between the pressure-free side edges no longer necessary.
- FIG. 4 shows a further embodiment of a braking station of the sheet brake 5 with a controllable blown air nozzle arranged above the sheet conveying path.
- a blower tube 17 Above the brake band 9, a blower tube 17 is arranged, which directs blown air from a Blas Kunststoffzuschreib 15 on the brake band 9.
- An axial adjustment of the blower tube 17 is preferably carried out together with the axial adjustment of the brake element.
- the common axial displacement takes place here via adjusting spindles 18, which are connected via sprockets 19 with a chain 20.
- the blast air units are thus moved by the brake elements associated with the engine.
- the intensity of the blown air discharged from the blower tube 17 is variable depending on the arc length and grammage.
- the beginning and end of the blowing air effect is also variable, wherein the blowing air is released by a pulse from a control valve 16.
- the connection of the blowing air takes place as a function of the printed image or motif.
- a rotary valve is used for suction air control for the brake band 9, this can be used via the chain 20 for blowing air control of the blower tube 17.
- blown air from the blower tube 17 is preferably used when the intake air is applied to the brake band 9 and the shutoff or intake air supply to the blower tube 17 is present when the blown air is applied to the brake band 9.
- FIG. 5 shows a further embodiment of a braking station of the sheet brake 5 with arranged above the sheet conveying path controllable Blas Kunststoffdüse.
- This braking station contains a pressure sensor 14 which is in operative connection with the air duct 8 and which is in communication with the control device.
- a blower tube 17 is arranged, which is connected via a control valve 16 with a blown air supply 15.
- the blowing air is controlled via the braking station as a function of the suction air build-up or -reduction measured by the pressure sensor 14. Further, a correction of the setting of a gripper opening of the gripper carriage 3 and the speed of the brake element according to the measurement result of Saugluft organized or -abbau by the control device. There is a precise connection or disconnection of the blast air and thus a shortening of the light-off of the sheet 1 to the suction belt. Markings are avoided because no overlap of the sheet trailing edge of the leading sheet 1 enters through the sheet leading edge of the next sheet. In addition to the monitoring of the sheet deposition process and the automation of the sheet deposition process (gripper opening, braking speed) in particular the utilization of pressure-free sections in the area of the sheet leading edge is improved.
