ABSTRACT:
A mechanism for adjusting the vertical position of a format on a printing press is proposed which makes use of the rotation of a blanket cylinder. A pair of pawls engage and disengage with a pair of ratchet wheels, which turn when a pawl support plate turns by a preset angle with respect to the blanket cylinder. The rotation of the ratchet wheel is transmitted to the format cylinder, so that the vertical position of a format is adjusted.
