Abstract
Apparatus and method for centering a web roll includes providing a support (A) for carrying the web roll in longitudinal alignment with a driven belt forming a cradle supporting the web roll for unwinding and winding the web. The support (A) includes a conveyor having a motor (C) producing relative transverse movement between the web roll and the driven belt in response to a signal from a detector (B) in a direction toward centering the web roll in respect to the driven belt. A second detector (D) is movable in and out together with the first detector for sensing the other edge of the fabric for discontinuing the relative transverse movement. The support (A) includes a conveyor and a lift and tilt mechanism for placing the web roll upon a table preparatory to moving same onto the cradle for unwinding.
