The present invention relates to a method for machining of a surface (31) of a roll in a twin-wire press (2), comprising lower rolls (4, 6, 8, 25~), an endless lower wire (10), upper rolls (14, 16, 18, 25~~), and an endless upper wire (12). The rolls comprise a coating (32). An apparatus (50) having a movable machining tool (54) for machining of the coating (32) is arranged in connection to a space between a wire (10, 12) and a roll (4, 6, 8, 14, 16, 18, 25~, 25~~). The machining tool (54) of the apparatus is moved, in contact against the surface of the roll (31) for cutting of the coating (32) to a desired level during rotation of the roll. The present invention also relates to an apparatus (50) for machining of a surface (31) of a roll in a twin-wire press for dewatering of a fibre suspension comprising said apparatus.
L'invention concerne un procédé d'usinage de la surface (31) d'un rouleau dans une presse double toile (2) comprenant des rouleaux inférieurs (4, 6, 8, 25'), une toile inférieure sans fin (10), des rouleaux supérieurs (14, 16, 18, 25'') et une toile supérieure sans fin (12). Les rouleaux comportent un revêtement (32). Un appareil (50) pourvu d'un outil d'usinage mobile (54) servant à usiner le revêtement (32) est disposé en rapport avec un espace compris entre une toile (10, 12) et un rouleau (4, 6, 8, 14, 16, 18, 25', 25''). L'outil d'usinage (54) de l'appareil est déplacé et mis en contact avec la surface du rouleau (31) afin de découper le revêtement (32) selon un niveau désiré pendant la rotation du rouleau. L'invention concerne également un appareil (50) d'usinage de la surface (31) d'un rouleau dans une presse double toile (2), ainsi qu'une presse double toile comprenant ledit appareil et servant à essorer une suspension de fibres.
