A cylinder is arranged to receive one or more hollow cylinders on an outer surface of the cylinder. The cylinder has at least one movable stop with at least one movable element. In an idle position the at least one movable element does not protrude beyond the outer surface of the cylinder and allows hollow cylinders to be slid over the cylinder, and in an active position it protrudes beyond the outer surface of the cylinder and acts as a mechanical stop for hollow cylinders. The at least one movable element can be moved from the idle position to the active position, and vice versa, by means of a rotary movement. A method for positioning a hollow cylinder on a cylinder of this kind.

Cylinder with movable pin, and mounting and dismounting method

Described herein is an adapter sleeve for adapting the internal diameter of cylindrical hollow cylinders to the external diameter of a cylindrical roller, comprising a sleeve body with (as viewed from the inside to the outside) a deformable base sleeve, optionally an intermediate layer and a top layer. The adapter sleeve furthermore contains a first gas distribution system and a second gas distribution system, which are connected to a gas inlet. The first gas distribution system is connected to at least one first gas outlet, which opens on an outer lateral surface of the adapter sleeve. The second gas distribution system has a cavity, which is designed, when supplied with a pressurized gas, to transmit pressure from the inside to the deformable base sleeve in such a way that the internal diameter of the sleeve body is reduced, at least in a partial region of the adapter sleeve, by a deformation of the base sleeve.
