A B S T R A C T For the purposes of removing a used stencil or an ink screen from the cylinder(s) of a duplicator, a rotatable core alongside the duplicator cylinder is driveable by a drive transmission from the main duplicator drive, by way of a freewheel clutch such that the core is driven only when the duplicator cylinder is rotated in the reverse direction as compared with the normal direction of rotation during printing, and also by way of a friction-slip connection arranged such that with no slip the peripheral speed of the core is higher than that of the duplicator cylinder along which it is mounted.
