Split end ring for rotary printing screen and method :

ABSTRACT

?

An end ring assembly for attachment to a cylindrical rotary printing screen includes an annular support ring adapted to be attached to an interior wall of the cylindrical rotary printing screen, and a drive ring adapted to be releasably attached to the annular support ring in position registration with the support ring to maintain alignment therewith upon rotation of the drive. A method of cleaning and/or storing a cylindrical rotary printing screen includes providing a cylindrical rotary printing screen having two opposed ends, and providing an end ring assembly on each end of the screen. Each end ring assembly has an annular support ring attached to an interior wall of the cylindrical rotary printing screen and a drive ring releasably attached to the annular support ring in position registration with the support ring. The drive rings are removed from the respective support rings, so that printing screen can be cleaned and/or stored with the support rings still attached.

?

The screen is usually permanently attached to an end ring at each end of the screen. Removal of the screen from the end rings typically destroys the screen. Thus, the end rings can be salvaged for re-use, but the screen cannot be easily cleaned unsupported once it is unattached from the end rings even if the screen survives the removal intact. Even if a careful arrangement is made to store the screen with the heavy geared end rings attached, the expensive geared end rings are then unavailable for use with other printing jobs until they are ultimately recovered from the screen. Thus, if a mounted screen for a particular print job is to be taken from a printing machine and stored while other print jobs are completed, extra ones of the expensive geared end rings are required.
