ABSTRACT:
The shaft for supporting cut roll portions in a cutting-reeling machine includes a cylindrical body, the outer surface of which has at least one recess for housing a resilient envelope which can be connected to a source of fluid under pressure by ducts in the cylindrical body. The shaft includes a plurality of rings open along respective generatrices, disposed side by side around the outer surface of the body and coaxial with the axis of the shaft. The rings have radial edges for engagement with grooves in the body of the shaft which allow them to expand circumferentially as a result of the inflation of the resilient envelope.
