- the suction and / or blowing air of the brake station 6 may preferably be infinitely adjustable or adjustable. Particularly preferably, a timing of the suction and / or blowing air of the brake station 6 by an air control element, in particular a rotary valve, which the brake station 6, for example, in the base body 7 integrated, can be assigned.
- a rotary valve may have recesses for separately controlling the suction air of a catcher element, not shown, and two pneumatic connections for the functional unit.
- Such a rotary valve can be actuated, for example, by the second drive element, in particular the second square shaft drive 9.
- a drive shaft, especially square shaft, of the second drive element can be driven by a single servo motor 25, for example.
- the servomotor 25 outside the frame or the frame wall of the display mounted on a, for example, on the drive side of the machine arranged fixing plate 22, in particular screwed be.
- the drive movement of the servomotors 24, 25 is preferably adjustable and / or tunable to the bow sequence.
- a cyclic pneumatic control in particular a control of the intake air, to a catcher element, not shown, and / or each functional unit used, in particular the squeegee 16 with brake band 17, take place.
- the sheet brake 5, in particular one, several or all braking stations 6, is associated in particular with a cleaning device which has at least one nozzle for the surface to be cleaned for cleaning the actuator and / or at least one surface of at least one brake station.
- This at least one nozzle of the cleaning device in particular directs a blown air jet to a connection point, in particular between a threaded spindle 12 and an adjusting element 13 and / or a surface of the first square shaft drive 8 and / or a surface of the second square shaft drive 9 and / or a guide surface 14 for the braking station 6
- a cleaning device may be a movable one Have nozzle or, for example, have a plurality of nozzles that are directed or directed to the corresponding locations of the brake station 6.
- a nozzle of the cleaning device can be arranged, for example, laterally on the main body 7 of the brake station 6.
- a cleaning device has a blown air source or a compressed air connection which is in operative connection or flow connection with at least one, for example, controllable or controllable compressed air source, for example a compressor. There may also be other Blas Kunststoffmaschinen in communication with the cleaning device.
- a blown air source for example, an axial pressure to be applied to the suction air connection 1 1 overpressure serve.
- a blowing air jet is generated by a cleaning device, which acts as a short-term blast air impact, for example, on the respective surface to be cleaned.
- a blown air jet or blown air blow through the at least one nozzle at intervals by the cleaning device in response to an axial adjustment of the brake station 6 and / or manually initiated dischargeable.
- an axial adjustment of one or more braking stations 6 of the sheet brake 5 may be necessary.
- the axial adjustment of one or a respective brake station 6 takes place by means of the actuator via the adjusting element 13 of the respective Braking station 6, wherein the adjusting element 13 is guided by means of the flat guide surfaces 14 on the guide cross member 10 and thereby carries the brake station 6.
- a brake station 6 is preferably guided or moved at a distance S1, S2 to the adjacent traverse, in particular to the trailing edge cross member 18, and / or to the further traverse 20.
- the brake station 6 is thereby preferably exclusively and at least approximately free of play held and guided by means of the guide surfaces 14 of guide cross member 10 and actuator 13.
- An axial adjustment of the brake station 6 can be made so along the waves spaced from the trusses 18, 20 made by the actuator.
