- the invention relates to a device for generating an air flow in a Duplicating machine, in particular in a printing press, according to the preamble of claim 1.
- the invention further relates to methods for guiding and depositing flat Products, especially substrates, in duplicating machines according to the Preamble of claims 15 and 16.
- the invention further relates to a method for zone-wise powdering of Printing materials in reproduction machines, according to the preamble of claim 17.
- duplicating machines for example in printing machines, which process flat or sheet-shaped flat products, especially substrates, to support the transport of the flat products by an air flow.
- sheets of paper are processed in rotary printing presses Transport gripper guided on a front edge of the sheet and in addition it is trailing arch surface supported by an air cushion. This can prevent that the sheet touches and damages components of the printing machine or that the freshly printed ink is smeared.
- Such a guide device for an arch with an air flow between the arch and a sheet guide surface is known from DE 43 08 276 A1.
- a respective bow is exposed to an air flow generated by a plurality of air jets is, which from flow channels arranged in the sheet guide surface in the form of Emerge through the sheet guiding surface.
- a guide device of the type described has the disadvantage that it is precise Setting the air flow is not possible because of the strength of the individual air jets cannot be regulated continuously. To change the generated Flow profile would also have to replace the control device for a second Guide device with modified nozzle arrangement.
- a fan was developed by ETR-GmbH, Dortmund, which also uses the acceleration of charged air molecules between a discharge electrode and a target electrode to generate flow, and reaches flow speeds of up to 3 m / s. It is also proposed to combine individual fans to form fan arrangements, for example as a planar, chessboard-like arrangement, so as to increase the flow cross section. With a cross-sectional area of 1 m 2 , a volume flow of 11,000 m 3 / h can be generated with the fans described.
- the inventive device for generating an air flow in a Duplication machine, in particular in a printing press, which has at least one Has fan unit, is characterized in that the at least one fan unit comprises at least one ion fan.
- the device according to the invention enables the printer to precisely control the Air flow via the voltage supply of the ion fan.

- a flow field can be any one Contour, for example, the flow strength can be transverse to the direction of transport of a flat product in a duplicating machine towards the edge areas lose weight.
- Detection devices the location of the free end of a flat product in space determine and the local strength of the flow field, for example over a Control device to vary such that this position is a desired target position of the free end of the flat product is approximated. It is still possible to use Presence detection devices to determine whether there is a flat product in the Located near one or more ion fans and in the absence of the flat product to at least reduce the performance of the respective ion fans.
- the air flows of individual ion fans can also be different Have directions. This can be done, for example, by the mechanical alignment of the Individual fans take place or in a preferred manner in that the target electrodes of the Fans are constructed in such a way that they can be controlled in segments. So for Example the ring-shaped target electrode of a fan can be divided into four segments, which can be individually supplied with a voltage, whereby the ion current of of the discharge electrode to the energized segment of the target electrode is steered and thus leaves the ion fan in a variably controllable direction.
- a device can also be characterized in that the at least one fan unit adjacent to a transport path of flat products, especially of printing materials, for example paper sheets or cardboard sheets, is arranged. Due to the inventive adjacent arrangement to the Transport path, it is advantageously possible to transport the flat products to be influenced favorably by the air flow generated by the fan unit or to support leaders.

- the ion fans in two different directions, so that for example in the direction of the printing material sheet sucking or blowing on this can be influenced.
- This can be the case with the above Printing sheets during transport by a sheet processing machine, for example be advantageous, the trailing end of the guided substrate sheet with overpressure to act upon touching these ends of the substrate sheets with the To prevent blowing devices or other guidance devices, it can also be of advantage to have a trailing end of a guided substrate sheet To apply negative pressure.
- the front end of the Printing material sheet is held by transport grippers of the transport cylinder, the trailing end of the substrate sheet by a generated negative pressure on the Suck and hold the transport cylinder, thereby touching the trailing end with other components near the transport path of the Prevent substrate sheets.
