Abstract: A mounting device is provided for an ink duct of a printing press wherein the ink duct is supported primarily on the press frame so as to be pivotally movable with respect to a ductor roller. The ink duct carries a first guide roller which engages the ductor roller in substantially the same plane as the ink metering elements disposed in the ink duct and the ink duct carries a second guide roller which engages the ductor roller substantially vertically above its center line. A link pivoted to the ink duct carries a third guide roller which is normally biased into engagement with the ductor roller at a position disposed from the first guide roller by at least 180.degree. measured peripherally around the ductor roller through the second guide roller. An unlocking mechanism swings the third guide roller out of engagement with the ductor roller so as to permit pivotal movement of the ink duct and guide rollers away from the ductor roller.

Abstract: For the rapid simultaneous engagement, disengagement and adjustment of all the applicator rollers at the plate cylinder of a printing machine, cam discs are mounted on the journals independently of the plate cylinder bearing. In an offset printing machine, the inking and damping rollers are each associated with their own cam discs. The cam discs are pivotable by means of drives, about the journals, with respect to adjustable stops for the engagement positions and end stops for the disengaged positions of the applicator rollers. The applicator rollers are mounted on rocker arms with respect to the stationary axis of the distributors preceding the applicator rollers and are adjustable with respect to the plate cylinder through the agency of adjustment means which co-operate with the cam discs. Adjustment of the applicator rollers during operation is effected by way of the cam discs which, in addition to the disengagement lobes, have cam zones for the roller engagement and adjustment.

Abstract: Apparatus for introducing starting materials into the shearing gap of a machine for producing plastic films, ribbons, foils or plates. A plasticized plastic starting material is severed into strings having a length substantially equal to the working width of the shearing gap and the resultant strings are introduced into the shearing gap substantially simultaneously over the width of the gap. The apparatus greatly increases the capacity of the machine, the homogeneity of the product over the entire width and the capability of the machine to supply a greater number of starting materials.
