ABSTRACT:
An unwind stand for positioning and controlling the unwinding of large paper rolls to processing machines is mounted on wheels riding on rails and motor driven through hydraulic motor to providing gripping and longitudinal movement of the rolls. Swinging gripping arms are mounted on the stand and disposed to grip the ends of the roll and raise it above the floor and hold it in position and provides for unwinding. The arms are capable of longitudinal movement along the axis of the roll, either individually or simultaneously, for flexibility in picking up the roll and locating it into operating position. A device is provided for final axial adjustment in alignment with the processing machine in a transverse direction and a device for gripping the rails to hold the machine in a fixed position and to prevent its tipping over. The entire stand and all its functioning elements is operated from a platform located on a cab in which are positioned various control elements for operation of the hydraulic components of the stand.
