PNEUMATICALLY FIXED ADAPTER SLEEVE Russian patent published in 2023 - IPC B41F27/10 

FIELD: mechanisms.

SUBSTANCE: claimed group of inventions relates to an adapter sleeve for alignment of an inner diameter of cylindrical hollow cylinder with an outer diameter of a cylindrical roller; as well as to systems including the specified adapter sleeve and methods for mounting/dismounting of a hollow cylinder on a cylindrical roller, using an adapter sleeve. The sleeve includes a case containing a deformable basic sleeve in an inside out direction, an intermediate layer, and a covering layer, the first and the second gas distribution system, which is connected to a gas inlet. The first gas distribution system is connected to one first gas inlet moved to an outer side surface of the adapter sleeve. The second gas distribution system has a hollow space intended for that, when supplying gas under pressure, pressure is transmitted from the inside to the deformable basic sleeve in such a way that an inner diameter of the sleeve case, due to deformation of the basic sleeve, decreases at a separate section of the adapter sleeve.

EFFECT: simplification of dismounting and mounting of an adapter sleeve, which, when loaded with gas, is fixed, allowing to remove only a hollow cylinder.
