发明名称 Roller structure at the press section of a paper making machine
摘要 The press section of a paper making machine has rollers in pairs, forming a press gap between them. Each roller has at least one end piece (1,2) and a mantle (3) in a frame structure (6). The frame (6) and at least one roller end piece (1,2) have limit stops and limit surfaces (5), working together when the roller is mounted to the frame (6). The press section of a paper making machine has rollers in pairs, forming a press gap between them. Each roller has at least one end piece (1,2) and a mantle (3) in a frame structure (6). The frame (6) and at least one roller end piece (1,2) have limit stops and limit surfaces (5), working together when the roller is mounted to the frame (6). A system (5') gives an adjustment to at least one roller end piece in relation to the frame, and at the same time gives support when the mantle is removed from the end pieces (1,2) while the roller is at the machine. An Independent claim is included for a procedure to remove a worn roller mantle for repair or replacement. The roller end pieces (1,2) are shifted along the roller axis, and the roller mantle (3) is carried by a crane. At least one roller end piece (1,2) is supported at the frame of the press section, when displaced, so that the mantle (3) can be detached from the other end piece and lifted clear. Preferred Features: The roller end pieces (1,2) can be given an axial movement, clear of the mantle (3), to be supported by frame (6) while the released mantle (3) is lifted clear. The frame (6) has a longer mounting limit surface (5') across the machine than the length of the assembled roller. The frame (6) and the roller end pieces (1,2) have a mounting structure to adjust the final roller assembly, such as a T-groove, elongated opening, and the like. The mounting has an elongated opening or similar as a guide.
