摘要:
In the present invention, the following steps are carried out: a plate drum transfer step (S1) in which a rubber drum (B), a plate drum (P), and an impression drum (I) are caused to separate, and in a state where the impression drum (I), the plate drum (P), and the rubber drum (B) are caused to rotate, ink is transferred to the plate drum (P) from an ink application roller (R) and the ink from the ink application roller (R) is transferred so as to be further layered onto the ink transferred onto the plate drum (P); a blanket drum transfer step (S2) in which when the rubber drum (B) and the plate drum (P) are opposingly brought into contact with each other and ink from the plate drum (P) is transferred to the rubber drum (B), the transfer of ink is begun from the transferred ink that was layered onto the plate drum (P), and ink from the plate drum (P) is transferred so as to be further layered onto the ink transferred onto the rubber drum (B); and a sheet transfer step (S3) in which when the rubber drum (B) and the impression drum (I) are opposingly brought into contact with each other and ink from the rubber drum (B) is transferred to a sheet of the impression drum (I), the transfer of ink is begun from the transferred ink that was layered onto the rubber drum (B) to the sheet of the impression drum (I).
摘要:
There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).

摘要:
The invention relates to a cylinder in a rotary press, in particular, for interacting with a form cylinder for a gravure press. According to the invention, the cylinder is improved with regard to its variable adaptability by the provision of a linear drive located at the end of the cylinder between the fixed support and rotating outer surface. Said linear drive operates in a vertical radial direction upwards toward the inner ring of a roller bearing.

摘要:
The invention relates to a flexion-controllable roller (100), comprising a plurality of inner support elements (10) that can be individually controlled by valves. The valves comprise actuators (80) with a shaped body (90) that changes its expansion in at least one dimension when an electrical current is applied. Said change serves to control the valves (50).
摘要:
Die Erfindung betrifft eine Druckmaschine mit mindestens einem Gegendruckzylinder (1) und mindestens einem Druckwerk mit Formatzylinder und Farbwerk (2), dessen Formatzylinder an den Gegendruckzylinder (1) anstellbar ist. Zur Lösung der Aufgabe, eine Druckmaschine dieser Art zu schaffen, bei der ein Antrocknen von durchgeschlagener Druckfarbe auf dem Gegendruckzylinder (1) ausgeschlossen ist, ist dem Gegendruckzylinder (1) in dem Bereich zwischen der zugeführten und der abgeführten zu bedruckenden Bahn, in dem dieser nicht von einer Bahn umschlungen ist, eine Sprüheinrichtung (6) zum Aufsprühen eines das Antrocknen von Farbe verhindernden flüssigen Trenn- oder Lösungsmittels auf den Gegendruckzylinder (1) zugeordnet.
