Abstract
A vibrator control is arranged to produce a brief pause or interruption in the movement of a vibrator roller before the vibrator alternately engages with an ink ductor and with a distributing roller wherein the arms of a pair of rocking levers which journal the vibrator roller at both ends are each operatively connected to an oscillating forked lever on alternate sides by means of opposed adjusting screws which cause the rocking levers to bear against one of two resilient abutments disposed opposite one another on the press frame. The adjusting acrews are adjusted so that a gap is alternatiely created between each of them and the rocking lever as the forked lever moves to the center of its oscillating stroke.
