ABSTRACT:
An apparatus comprising a fixed roller and a movable roller movable toward and away from the fixed roller to correct the deviation of a travelling fabric by nipping a selvage thereof with the two rollers. The movable roller is biased by a spring toward the fixed roller for nipping the fabric but is normally held away from the fixed roller by a forward stroke of a cylinder against the action of the spring. The spring is provided with a member for adjusting the spring force, and the stroke of the cylinder is also adjustable. The axis of the movable roller is slightly shiftable automatically relative to the fixed roller to assure proper nipping engagement with the fabric.
