Die Erfindung betrifft außerdem ein Verfahren zum Wechsel einer Druckform und zur Aufnahme einer Produktion.
摘要:
Method for setting the spacings between cylinders of an inking unit which delimit at least two cylinder nips, and in which method the spacings are set on the basis of measured values which are obtained from the surface of at least one of the cylinders of the inking unit. It is considered to be novel and inventive that, during the setting of the spacing between the two cylinders which delimit a second cylinder nip, knowledge is used which was obtained during the setting of the spacing between the two cylinders which delimit a first cylinder nip. A printing press for carrying out the described method is also described and claimed.
摘要:
There is described an intaglio printing press comprising (i) a stationary machine frame (01 ) supporting an intaglio printing cylinder (07) and an impression cylinder (06) contacting the intaglio printing cylinder (07), and (ii) an inking system (12, 13, 16) for inking the intaglio printing cylinder (07), which inking system (12, 13, 16) comprises an ink-collecting cylinder (12) designed to contact the intaglio printing cylinder (07) and at least one inking device (13, 16) for supplying ink to said ink-collecting cylinder (12). The intaglio printing press further comprises a driving system (110; 115; 116) for rotating the ink-collecting cylinder (12) independently of the intaglio printing cylinder (07) and the impression cylinder (06) at least during maintenance operations.

The intaglio printing press further comprises a correcting and adjusting system (80) for correcting and adjusting a rotational position of the ink-collecting cylinder (12) with respect to a rotational position of the intaglio printing cylinder (07) following maintenance operations to ensure proper circumferential register between the ink-collecting cylinder (12) and the intaglio printing cylinder (07) in the working position of the first mobile carriage (1 1 ).
摘要:
The invention relates to a transverse drive for a cylinder of a printing press, comprising a roller bearing (3) for mounting a printing press cylinder (2) with a degree of axial freedom, a torque motor (8) as rotary drive for the printing press cylinder (2), wherein the rotor (7) of the torque motor (8) is rigidly connected to a shaft journal (4) on the printing press cylinder (2) and a shaft journal extension (11) projecting over the torque motor (8) which engages with a linear drive (12) permitting a transverse movement of the printing press cylinder (2) with adjustable stroke.

摘要:
An ink fountain apparatus, method of method of adjusting printing characteristics in flexographic printing and a printing press system are disclosed. The apparatus may include a side plate, a roller disposed adjacent a first end of the plate, a back plate disposed adjacent a second opposing end of the side plate and a throttle disposed between the roller and the back plate. The throttle is mounted to the side plate and includes a back surface facing towards the back plate and a front surface facing towards the roller. The front surface includes a curved portion forming a tapering gap between the roller and the front surface of the throttle. A position controller is coupled to the throttle to selectively move the curved portion towards and away from the roller to adjust the volume of ink being transferred to the outer surface of the roller.
