Abstract: A holder and an insert for a metering device for coating liquid or viscous coating medium onto a moving material web. The holder being elongated and including an insert groove, a locking rod groove and a locking rod being movably received in the locking rod groove and being formed with locking portions adapted to project through a slot and with releasing portions. The insert being elongated and including a coating rod groove being adapted to rotatably support a coating rod, and one or more engagement formations being adapted to interact with the locking rod to allow the insert to be inserted into and released from the insert groove when the locking rod is in a releasing position, and to allow secure holding of the insert in the insert groove when the locking rod is in a locking position, in which the engagement formations is in engagement with the locking rod.

Abstract: A metering device, including a holder and an insert, for coating liquid or viscous coating medium onto a moving material web. The holder being elongated and mountable to a frame and comprising an insert groove in the longitudinal direction, adapted to receive an insert, and an engagement formation in the longitudinal direction along the insert groove. The insert being elongated and comprising a rod groove in the longitudinal direction, being adapted to rotatably support a coating rod having a circular cross section and being designed to surround the coating rod over more than 180° of its circumference, and an engagement formation in the longitudinal direction along the rod groove. The engagement formations of the holder and the insert are designed to interact with a locking member to allow interconnection between the insert and the holder of the metering device.

Abstract: An applicator beam in a size press comprising a nip formed by a pair of press rolls between which a paper or board web is passed. The press rolls are provided with coating devices for spreading films of coating agent onto the faces of the rolls. The coating devices are mounted on applicator beams placed in the transverse direction of the machine. The applicator beams are linked pivotally on the frame of the size press or on the loading arms of a displaceable roll by a pivot shaft arranged transverse to the machine direction. The applicator beams are also provided with pivot cylinders by which the applicator beams can be pivoted between a closed position, i.e. the operating position, and an opened position, i.e. the service position.

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.
