Abstract

In some examples, a processing machine has at least one cleaning device for cleaning a substrate. The at least one cleaning device and the at least one substrate are able to be arranged in a first and a second cleaning state, and the substrate is arranged at a distance from the at least one cleaning device in the first cleaning state. The substrate is arranged in contact with the at least one cleaning device in the second cleaning state, and the at least one cleaning device and the substrate are arranged so as to be transferable at least from the first cleaning state into the second cleaning state. The at least one cleaning device is arranged to be adjusted from a first cleaning position in the first cleaning state into a second cleaning position in the second cleaning state.

First claim

The invention claimed is:

1. A web processing machine comprising:
at least one cleaning device for cleaning a substrate transported along a transport path, the at least one cleaning device comprising at least two flow elements and/or brushes;
the at least one cleaning device and the substrate configured to be arranged in a first cleaning state and a second cleaning state, wherein, in the first cleaning state, the substrate is arranged spaced apart from the at least one cleaning device and, in the second cleaning state, the substrate is arranged so as to be in contact with the at least two flow elements and/or the brushes of the at least one cleaning device;
the at least one cleaning device and the substrate being arranged so as to be transferrable at least from the first cleaning state into the second cleaning state;
the at least one cleaning device being arranged so as to be displaced from a first cleaning position in the first cleaning state into a second cleaning position in the second cleaning state, wherein, in the first cleaning position, the at least one cleaning device is functionally connected to a cleaning region on the substrate and/or on the transport path intended for the substrate, and wherein, in the second cleaning position of the at least one cleaning device, the cleaning region is arranged so as to be shifted on the substrate and/or on the transport path intended for the substrate; and
wherein, in the first cleaning state and in the second cleaning state, the at least one cleaning device is arranged so as to apply a suction force at least onto the cleaning region.

2. The web processing machine according to claim 1 , wherein a guide element deflecting the transport path of the substrate is arranged so as to increase a force component opposing the suction force applied onto the substrate in the cleaning region of the first cleaning position compared to the cleaning region in the second cleaning position.

3. The web processing machine according to claim 1 , wherein the cleaning device, during a displacement from the first cleaning position into the second cleaning position, is arranged so as to be displaced parallel to the substrate and/or the transport path intended for the substrate.

4. The web processing machine according to claim 1 , wherein the at least one cleaning device, at least in the first cleaning position, is arranged on a side of the transport path and/or the substrate that is opposite to a side of the transport path and/or substrate on which a guide element is arranged.

5. The web processing machine according to claim 1 , wherein the at least one cleaning device is arranged between a substrate source and a printing assembly.

6. The web processing machine according to claim 1 , wherein the at least one cleaning device is configured as a cleaning device comprising a vacuum chamber and/or an ionization device.

7. The web processing machine according to claim 1 , wherein a suction power of the at least one cleaning device is adaptable to a width of the substrate by switching on and/or off extraction connectors by means of multiple valves.
