Abstract: An applicator device for applying a coating agent onto a moving base, such as a paper or board web, onto the face of a film press roll, or equivalent, and a method for correcting for distortions arising from thermal strains in such an applicator device. The applicator device includes an applicator beam arranged in a direction transverse to a running direction of the moving base, a coating-agent feed pipe arranged in the transverse direction and mounted on the applicator beam, and coating members mounted on the applicator beam for applying a coating onto the moving base and spreading and smoothing the coating agent onto the moving base. The coating-agent feed pipe and the coating members are constructed as a single unit. The device also includes mounting members for mounting the single unit of the coating-agent feed pipe and the coating members on the applicator beam.

Abstract: A calender for a web including a calender frame and a stack of rolls mounted on the frame and consisting of four rolls arranged one above the other. In the stack, adjacent rolls placed one above the other are arrangeable in nip-defining relationship with one another so as to calender the web in the nips. The stack of rolls in the calender is composed of three variable-crown rolls, of which rolls the roll mantle of at least one roll is displaceable in relation to its roll axle in the direction of the nip plane by loading devices arranged inside the roll, and one heatable roll arranged between two variable-crown rolls. The rolls are preferably arranged vertically so that the two lowest rolls and the uppermost roll are variable-crown rolls and that the third roll from the bottom of the stack is a heatable roll.
