Abstract
The Extended Nip press apparatus of this invention has an endless loop nip blanket which is clamped at each end head by a circular array of twelve clamp segments which are positioned radially by the hydraulic actuation of an axially positionable circumferential clamp ring. The blanket is separately sealed by an air tube seal which extends between the clamp ring and the interior of the blanket. Because the clamping arrangement is independent of the seal, inadvertent loss of air pressure will not cause the blanket to become unclamped.
