Device for driving friction roller in printing machine has drive cam connected to motor for rotating cam about its rotation axis, adjuster of inclination of cam path relative to cam rotation axis

摘要

The device has a cam rotation axis (16) of a drive cam (17) for axially driving the friction roller (10) offset eccentrically relative to a roller rotation axis. The drive cam is connected to a motor (14) for rotating the cam about the cam's rotation axis and has an adjuster (55) for setting the inclination of a cam path (18) of the drive cam relative to the cam's rotation axis. Independent claims are also included for the following: a printing machine with a device for driving a friction roller.
