A paper machine includes a guide connected to a roll for moving an end of the roll in transverse directions to a longitudinal axis of the roll. The guide includes a support frame and a roll mounting frame pivotally connected to the support frame at a pivot axis. The roll mounting frame is connected to and rotatably carries the roll. Two positioning devices are respectively disposed between and engage each of the support frame and the roll mounting frame on opposite sides of the pivot axis. The two positioning devices pivot the roll mounting frame about the pivot axis and thereby move the roll in one of the transverse directions. The two positioning devices coact to maintain the roll mounting frame in one of a plurality of positions relative to the support frame.
