摘要:
A printing press (10) including a frame (22) and a central impression drum (20) rotatably supported on the frame. A plurality of first side printing stations (24) is circumferentially spaced about the central impression drum and in communication therewith. Each of the plurality of printing first side printing stations is adapted to print an image on a first side of a substrate (11). A perfecting printing station (36) is disposed at a position about the central impression drum. The perfecting printing station includes a multi-purpose drum (38) having a substrate retainer (44) for securing the substrate thereto. The multi-purpose drum forms an impression cylinder and is in communication with an image transfer cylinder (40) for imparting an image on a second side of the substrate. An ink fixing unit (70) is disposed between the first side printing stations and the perfecting station. The ink fixing unit fixes the image on the first side of the substrate prior to the image being imparted on the second side of the substrate by the perfecting station.

Druckprodukte werden in Form von Teilstapeln (112 bis 115) auf einem Förderband (124) kreuzweise mittels gabelförmiger Halterungen (116 bis 119) abgelegt. Die Halterungen (116 bis 119) werden jeweils paarweise gegeneinander verschwenkt, so daß die Teilstapel (112 bis 115) übereinandergelegt werden (112′, 112˝). Durch gegenläufig verschiebbare Zungen (127, 128) werden die Teilstapel (112, 113) jeweils aus den Halterungen (116 bis 119) herausgeschoben, wonach der kreuzgelegte Teilstapel (112 bis 115) auf dem Förderband (124) weitergeführt wird.
摘要:
When a blower device (51; 52) is being operated in a discharging device (03) having a first and a second stack-delivery means (I; II), wherein the blower device (51) is provided above a transport path of sheets (B) conveyed along a transport direction (T) by a conveying system (21) and above a deposit location of the first stack-delivery means (I), in a first operation mode, a sheet (B) which is to be deposited in the first stack-delivery means (I) is supplied from above with blowing air coming from the blower device (51; 52). The blowing device (51) comprises a plurality of groups (113q) provided one behind the other in the transport direction (T) and running transversely to said transport direction (T), each group having a plurality of blowing-air openings (114r) which are directed towards the transporting path and are supplied from within with compressed air at a pressure of more than 0.6 bar above normal pressure.
