Title:
METHOD AND DEVICE FOR PERFORMING OPERATION STEPS IN ADJUSTMENT OF PRINTING PRESS
Document Type and Number:
Japanese Patent JP3037575
Kind Code:
B2
Abstract:
PURPOSE: To automate the adjustment process of a printing press using an adjusting servo force when a print program is switched, especially when a sheet-fed printing press is switched from single side printing to both sides printing or vice versa.
CONSTITUTION: Means on the method is, by a pressure medium system having a pressure limiter where the pressure stage can be switched, is to load a second pressure medium system connected with a plurality of servo cylinder units 12 preloaded, at least partially, with different force and means on a device is provided with a pressure converter 1 comprising a piston cylinder unit having a differential piston 3. First effective piston face 4 of the differential piston can be loaded with a pressure medium having controllable pressure stag of a first pressure medium system in one cylinder chamber 6 and second effective piston face 5 of the differential piston acts in the cylinder chamber 10 of the second pressure medium system connected with the plurality of servo cylinder units 12.
