Abstract
A printing plate is mounted peripherally of a first plate cylinder or a second plate cylinder by using a forward-end clamping mechanism having a forward-end clamping jaw and an air cylinder for opening and closing the forward-end clamping jaw, and a rear-end clamping mechanism having a rear-end clamping jaw and two air cylinders for opening and closing the rear-end clamping jaw. The forward-end clamping mechanism is used for clamping the forward end of the printing plate. The rear-end clamping mechanism is used for clamping the rear end of the printing plate and straining the printing plate over the periphery of the first or second plate cylinder.
Claims19
A printing plate mounting apparatus for mounting a printing plate peripherally of a plate cylinder, comprising:
- a forward-end clamping jaw disposed peripherally of said plate cylinder for pinching a forward end of said printing plate with a clamping base;
- a forward-end clamping jaw switching means disposed on one end surface of said plate cylinder for opening and closing said forward-end clamping jaw;
- a plurality of rear-end clamping jaws disposed peripherally of said plate cylinder for pinching a rear end of said printing plate with a clamping base;
- a rear-end clamping jaw switching means disposed on one end surface of said plate cylinder for opening and closing said plurality of rear-end clamping jaws together, and
- straining means disposed on said plate cylinder for moving said rear-end clamping jaws in a direction for straining the printing plate pinched.
