Abstract:
In a rotary printing press having a rotatable cylinder provided with a channel therein extending in general parallelism with an axis of rotation of the cylinder and directed generally radially into the cylinder from an outer surface thereof, wherein the channel is adapted to receive a leading leg and a trailing leg of a flexible plate, a device for securing the plate on the cylinder comprising:a bore in said cylinder extending in general parallelism with the axis of rotation thereof and communicating with said channel, an operating shaft rotatably positioned in said bore for rotation between a plate-securing position and a plate-releasing position, a plurality of tines spaced axially along and extending generally radially outwardly from said shaft and each tine having a generally conically shaped nose provided with a generally flat tip, each of said tines penetrating said trailing leg of said plate to releasably grip said trailing leg and secure said plate in said channel upon rotation of said shaft to said plate-securing position, said channel having a wall facing said bore, and said tines compressing said leading leg of said flexible plate against said wall upon rotation of said shaft to said plate-securing position.
