ABSTRACT:
A lateral positioner and adjust mechanism is provided for an unwind station of a web press. The unwind station includes first and second arms pivotally mounted to a frame that cooperate for supporting for rotation a roll on a shaft. The arms can be raised and lowered to raise and lower the roll. In the subject mechanism, a wheel is mounted to a first end of the shaft extending beyond the first supporting arm, the wheel defining in its periphery a groove having opposing side walls. Each of the side walls defines an outward bevel. A block attached to the first arm defines thereon a ridge extending upwardly perpendicular to the shaft, the ridge having opposing side walls, each of which includes a bevel. The ridge is fittable within the groove. The block can be selectively moved toward and away from the first arm in a direction parallel to the shaft. As the roll shaft is raised into position, the ridge and groove engage, moving the shaft into correct lateral position. During operation of the press, lateral movement of the block will provide lateral adjustment of the roll.
