Abstract
An apparatus for displacing the roll mantle end pieces of shoe press, said shoe press comprising a press roll (1) and a backing roll, said press roll (1) comprising a rotating, liquid-impermeable roll mantle (2), a solid and preferably non-rotatable support beam (3) going axially through the roll mantle and having a stub shaft (4, 5) at each end of it, at least one press shoe supported by the support beam and having a concave surface part, elements for pressing the concave surface part against the roll mantle so that the mantle together with the backing roll can form a pressing zone, two roll mantle end pieces (6, 7) axially movable on each stub shaft, fastening elements for fastening the axial ends of the roll mantle to each roll mantle end piece. The apparatus comprises a multi-chamber cylinder unit (8) functionally connected to both roll mantle end pieces, said cylinder unit being disposed inside the support beam (3) and used to move both roll mantle end pieces (6, 7).
