Abstract: A longitudinally displacable roll apparatus supporting a web (16) of record material is designed to maintain the roll (18) in proper alignment with associated processing equipment as the web is paid from, or wound onto, the roll. The apparatus comprises a pair of frame members supporting the roll. The roll is rotated by a drive shaft (195) having an interengageable coupler on the drive shaft and one end of the roll, to permit the roll to be rotatably driven by the roll drive shaft while not being directly secured thereto. The other end of the roll is engaged by means for displacing it longitudinally in accordance with signals derived from the actual path of the web so as to keep the web accurately on its intended path. The longitudinal and rotational drive system are able to operate independently of each other.
