Offset rotary printing machine

摘要

The rubber blanket cylinder (2) is detachable from the plate cylinder (1) and or from the pressure cylinder (3). Bearing rings (4) on support rollers (R1,R2) support the rubber blanket cylinder on each side. The first support roller (R1) is diametrically positioned in relation to the plate cylinder on the extension of the line (L1) connecting the centre of the plate cylinder and the centre of the rubber blanket cylinder. The second support roller (R2) is positioned at an angle of roughly 100 degrees from the extension of the connecting line opposite the pressure cylinder. The spring-loaded support roller (R) is opposite the second support roller.
