Abstract

Die Erfindung betrifft eine Druckmaschine, insbesondere eine Bogendruckmaschine, mit einem Gebläse (14) zur Bereitstellung einer definierten Luftströmung in einem von einem Bedruckstoff, insbesondere von Druckbogen, wegführenden oder in einem zu einem Bedruckstoff hinführenden Strömungskanal (13), wobei die Luftströmung insbesondere in einer Trocknungseinrichtung der Trocknung eines bedruckten Bedruckstoffs, insbesondere bedruckter Druckbogen, dient. Erfindungsgemäß ist in den Strömungskanal (13) ein Partikelfilter (16) integriert, um aus der Luftströmung Partikel, insbesondere Puderteilchen, herauszufiltern, wobei dem Gebläse (14) eine Regelungseinrichtung (17) zugeordnet ist, die eine Drehzahl des Gebläses (14) derart regelt, dass trotz zunehmender Verschmutzung des Partikelfilters (16) infolge aus der Luftströmung herausgefilterter Partikel der Volumenstrom im Strömungskanal (13) im wesentlichen konstant bleibt.

The invention relates to a printing machine, in particular a sheet-fed printing press, with a fan (14) for providing a defined air flow in a flow channel (13) leading away from a printing material, in particular printing sheets or in a flow channel (13) leading to a printing material, the air flow in particular in one Drying device of the drying of a printed substrate, in particular printed sheet, is used. According to the invention, a particle filter (16) is integrated into the flow channel (13) in order to filter out particles, in particular powder particles, from the air flow, the fan (14) being associated with a control device (17) which controls a speed of the blower (14) in that, despite increasing contamination of the particle filter (16), the volume flow in the flow channel (13) remains essentially constant as a result of particles filtered out from the air flow.
