Abstract
The liquid-distributing roller assembly for printing machines is composed of two opposite pairs of guiding tracks secured to the machine walls. One track supports for rectilinear movement a two-stage transmission gear unit in which one end of the shaft is supported for rotation; the other end of the shaft is supported for rotation and for a rectilinear movement in the opposite track. The shaft supports for rotation and for an axial displacement a liquid distributing roller which at one end is connected to a first spur gear rotatable on one end of the shaft and being in permanent engagement with an elongated transmission gear. The latter is also in permanent engagement with a second spur gear which is connected for joint rotation to the shaft. The other end of the shaft supports a cam which engages a cam follower connected to the distributing roller so that as soon as the latter is rotated an axial reciprocating movement is generated by the cam mechanism.
