ABSTRACT:
A pullout roller assembly for a printing press comprising an upper roller and a mounting therefor, the mounting including a bellcrank lever having an upright leg and a horizontal leg joined to the upright leg by an elbow. The roller is mounted on a fixed axis of rotation to the elbow and the outer end of the horizontal leg has a ball type universal connection to the frame of the press. The upper end of the upright leg has a pocket formed therein in which a spherical output end of a prime mover is positioned for exerting a force against a flat surface in the pocket without binding for biasing the lever and thus the pullout roller mounted thereon against the periphery of a companion roller, which is normally powered, for grasping a sheet or web of paper passing between the rollers and moving the paper through various stations of the press. The mounting of the lever and the nonbind arrangement the load-transfer joint features and the universal connection permit the pullout roller to float and peripherally conform to the position of the power roller so that both rotate on parallel axes thus avoiding uneven pull on the paper and scuffing and eliminating random sheet lengths.
