ABSTRACT:
A paper registration control device for printing presses includes a carrier having a plurality of holes extending vertically therethrough and arranged in tandem and a plurality of spherical pressure elements, each element adapted for seating in one of the carrier holes. A segment of each of the pressure elements projects below the carrier and floats within the carrier to thereby exert a constant pressure on paper being fed into the registering position. At least one of the spherical pressure elements has a weight different from the other pressure elements. Therefore, the pressure elements may be arranged in different patterns along the carrier to exert the optimum pressure necessary to provide exact register at substantially increased feed rates.
