Abstract
A mandrel for the support of a printing cylinder includes a hollow cylindrical shell, the axial ends of which are enclosed by trunnions and expansion heads. Compressed air is admitted into the shell through one of the trunnions and escapes through apertures in the hollow shell and into the interior of a printing cylinder, and, is employed to expand a resilient sheath positioned on the printing cylinder.
