Abstract
A bridge mandrel construction is provided which is simple to manufacture, light weight, and easy to mount and dismount from underlying printing cylinders in flexographic and gravure printing systems. The bridge mandrel includes a generally hollow, cylindrically-shaped tube adapted to fit over a print cylinder. A channel extends substantially around the circumference of the inner surface of the tube, and a plurality of orifices extends generally radially outwardly from the channel to the outer surface of the tube. The channel and orifices permit pressurized air to be provided from the interior of the mandrel to its surface for the mounting of a print sleeve onto the mandrel. In one embodiment, the bridge mandrel includes a locking mechanism which is adapted to engage the print cylinder to prevent movement of the mandrel during printing operations.
