Abstract
An apparatus for exchanging elastic rolls in a supercalender has a platform which is movable up and down between the frame of a supercalender and a magazine for spare rolls. The platform supports two cracks with horizontally movable guides for two supports which can engage the end portions of an elastic roll from below before the guides and the supports are moved horizontally to transfer the roll from the supercalender, across the platform and into the magazine. In order to temporarily detach guide rolls which are installed in front of elastic rolls, the platform further supports two tracks for jaw-shaped supports for the end portions of a guide roll which is transferred into the apparatus and remains in the apparatus at a level above the tracks for the supports which transfer elastic rolls.
