Title:
FEEDER FOR SUPPLYING PRINTING CYLINDER IN POLYCHROME ROTARY PRESS WITH LIQUID
Document Type and Number:
Japanese Patent JPS5957758
Kind Code:
A
Abstract:
The dampening unit of a rotary printing press is provided with additional transmission components and a swiveling stop mechanism so that the dampening unit can also apply a varnish having an arbitrary viscosity. For applying dampening solution to the plate cylinder (5) of the rotary press, the dampening unit has a fountain roller (13) feeding a transfer roller (15) and an applicator roller (16) which are driven by the press drive. When the dampening unit is used as a varnishing unit, clutches (28, 29) are enabled and disabled so that the transfer roller (15) is driven by a separate drive (17) which rotates the fountain roller (13). The applicator roller (16) is selectively thrown off by pneumatic actuators (32, 35) in such a way that all rollers (14-16) of the dampening unit are connected to each other and can be driven by the separate drive (17). A third position is also defined wherein the applicator roller (16) is also selectively thrown off 5/10 mm from the transfer roller (15). When the applicator roller (16) is thrown off the plate cylinder (11), the fountain roller (16) is preferably thrown on and off periodically by a pneumatic actuator (39).
