Abstract: This invention relates to a press device with a suction press roll. According to the invention, a linear force increase can be achieved in press devices with suction press rolls of identical or smaller size than conventional suction press rolls by equipping the suction press rolls with a compliance compensator. Said compliance compensator is arranged parallel to the longitudinal axis of the suction press roll in said suction press roll. Different concepts are possible depending on the roll cover construction and the arrangement of the suction box, whereby the one first embodiment is characterized by the integration of a shoe press roll in the suction press roll. A second embodiment is characterized by the combination of a routing of connection channels between the press nip and the suction box through the roll cover with an integrated compliance compensator in the interior space enclosed by the roll cover.

Abstract: A machine for the production and/or converting of a material web, especially a paper or carton web, such as a coating machine for single sided or two-sided application of liquid or viscid coating medium onto a moving web by way of at least one application device. At least one carrier surface, or partial surface, and/or at least one area or partial area, of the machine that is exposed, or could be exposed, during the operation and/or during start-up of the machine and/or during slow-down of the machine and/or during at least an exceptional operational condition of the machine to the medium is a focus of the present invention. Application medium, that is used in the production or converting process, and/or is subjected to another contamination hazard, is formed by or furnished with a permanent or temporary, protective layer, also referred to as barrier layer, that is applied to the carrier surface.
