Abstract

The pneumatic shaft for the holding of a roll of web material has a set of long inflatable components (411), whereby when the roll is installed on the body (3) of the shaft in sleeve form and the components are inflated, the far contact faces of the contact sides of a first roll contact piece contacts the roll to keep it on the shaft, and the far contact face of the contact sides of a second roll contact piece stabilizes the position of the roll of web material on the shaft.
