Device for clamping and holding a printing plate on an exposure drum

摘要

The apparatus has a clamping bar (9) connected to a pull rod that is guided through a guide bushing into interior of an exposure drum (1). A compression spring is disposed in the interior of the drum, where the compression spring pulls the bar onto the printing plate with the pull rod. The compression spring exerts a force upon the bar, and the bar is lowered vertically onto the plate for clamping a front edge of the plate.
