Patent ID: 7971529

Claim:
A rotary press assembly comprising: a hub rotatably mounted about a center axis in a rotary press and having an outer radial surface, the outer radial surface of the hub including: a hub stop surface at a first end of the hub, the hub stop surface having a frustoconical shape about the center axis; a hub supporting surface at a second end of the hub; and a central hub surface between the hub stop surface and the hub supporting surface, the central hub surface being cylindrical with a circular cross section; a format adaptation sleeve mountable on the hub and having an inner radial surface, the inner radial surface of adaptation sleeve including: a sleeve stop surface adjacent to a first end of the central sleeve surface, the sleeve stop surface having a frustoconical shape about the center axis; a sleeve supporting surface adjacent to a second end of the central sleeve surface, the sleeve supporting surface and the hub supporting surface defining an annular gap; and a central sleeve surface pressing on the outer central hub surface of the hub, the central sleeve surface being between between the sleeve stop surface and the sleeve supporting surface, the central sleeve surface being cylindrical with a circular cross section; and a deformable stop interposed between the sleeve supporting surface and the hub supporting surface in the annular gap for aiding in fixing the adaptation sleeve to the hub, the hub and sleeve supporting surfaces contacting the stop and fixing the adaptation sleeve to the hub, the adaptation sleeve being fittable onto the hub before insertion of the stop into the annular gap, the stop being axially inserted into the annular gap.
