US 5,401,315 A · Method and device in a size press

Abstract

A device in a size press comprising a nip formed by press rolls through which a paper or board web is passed. The press rolls are provided with coating devices for spreading films of a coating agent onto faces of the press rolls. The coating devices are mounted on applicator beams arranged transverse to the machine direction. The applicator beams are supported pivotally on the frame of the size press or on the loading arms of a displaceable press roll and are provided with pivot cylinders by which the applicator beams can be opened and closed in relation to the rolls corresponding to them. The applicator beams are further provided with catches supported directly or indirectly on bearings of the corresponding press rolls when the applicator beams are being closed by the pivot cylinders. At least one of the applicator beams of the size press is provided with catches at each end of the applicator beam and positioned in accordance with the position of the applicator beam. The catches are attached to the applicator beam by articulated joints and are interconnected mechanically.
