Abstract (en)
[origin: EP0559076A1] In a method and an apparatus for supplying ink to an ink roller for a rotary printing machine, the object consists in finely metering or apportioning the volume of ink in accordance with the production conditions dependent on the speed. According to the invention, this takes place due to the fact that a plurality of tubes (26, 33) are arranged coaxially on a hollow axle (11) fixed to the frame, which tubes each have bores (24, 29, 41) running in the radial direction. In this case, a first tube (26) which can be moved back and forth about an angle of rotation is arranged on the hollow axle (11). Located on the first tube (26) is a second tube (33) of polygonal cross-section. An outer tube (44) of porous material is driven at the speed of the machine. The second tube (33) has a controllable drive and a different speed from that of the outer tube. <IMAGE>
