Abstract
An extended nip press has a looped belt mounted over a shoe having a concave surface which presses the belt against a mating surface on a roll to provide an extended nip. The shoe has a support which is movable in a skewing sense relative to the longitudinal axis of the roll. Lateral movement of the belt is monitored. When it has moved beyond predetermined limits in either direction, the shoe is skewed to alter the frictional forces on the belt as it passes over the shoe's surface. This controls the position of the belt and keeps it centered in the nip.
