Abstract

An apparatus for removing liquid from a running web, comprising at least: an overpressure apparatus (10) which is placed on one side of the web (12) and through which overpressure can be effective on the web (12) running past said overpressure apparatus; and a running wire (19) which is placed between said web and said overpressure apparatus and through which the overpressure of the overpressure apparatus can be effective on the web, wherein said running wire (19) can be placed against the running web (12). A system for removing liquid from a running web also comprises at least a surface (6a, 7a) which is placed on the opposite side of the web with respect to said overpressure apparatus and against which the wire (4) is pressed by the effect of vacuum and through which the vacuum can be effective on the wire (4) running past said surface (6a, 7a) and further on the web. In a method for removing liquid from a running web, a running web (12) is affected by means of the overpressure of air by generating said overpressure by an overpressure apparatus (10) which is placed on one side of the web and past which the web is running, and moreover, a running wire (19) is introduced between said web and said overpressure apparatus, through which wire (19) the overpressure of the overpressure apparatus can be effective on the web, wherein said running wire (19) is simultaneously placed against the running web (12).

Abstract

Apparatus for applying overpressure to a moving web path (3, 16, 17), comprising at least: a surface (1a, 2a) against which the web path is pressed by the effect of negative pressure; a pressure box (19) which is placed on the opposite side of the web path with respect to said surface (1a, 2a) and through which the overpressure is effective on the web path travelling past said surface (1a, 2a), The pressure box comprises at least an overpressure chamber (22) restricting the overpressure area (24) subjected to the overpressure, wherein the overpressure chamber has the shape of a tapering or narrowing throat (23), having an air gap (28) between its narrow end and the web path and a channel (29) at its wide end, via which channel air is capable of being discharged from the overpressure chamber. In one example the pressure box (19) also comprises at least one overflow chamber (30) restricting the area (X2) subjected to the pressure of the overflow chamber, wherein both said channel (29) and said air gap (28) lead from said overpressure chamber to the overflow chamber.
