MECHANISM FOR ADJUSTING BLANKET-TO-BLANKET SQUEEZE OF PERFECTING PRESS Abstract Of The Disclosure The squeeze of two opposed paper-receiving rolls of an offset printing press may be infinitely adjusted within a relatively small range by virtue of the fact that, each end plate supporting the rolls has a slit therein between the axes of rotation of the rolls which will permit slight deformation of the plate in a direction transversely of the slit upon manipulation of an adjusting mechanism to shift the rolls toward and away from each other. Adjustment mechanism is provided on each plate and includes a cam that, when rotated by the longitudinal displacement of an operating link, has the effect of opening or closing a corresponding slit to thereby effect minute adjust- ment of the spatial relationship of the roll axes. The operating link has a specially threaded section from which the longitudinal displacement of the link is derived, the arrangement being such that the ratio of link rotation to link displace- ment is relatively high so that very fine adjust- ment of the critical roll relationship can be achieved.
