A process for applying markings or break notches on molded items or tablets, said process comprising:
- treating a surface of a molded item or tablet with a laser beam, said treatment being generally coterminous with ejection of the molded item or tablet from a die of a press.
A device for applying markings or break notches on molded items or tablets by means of a laser beam, comprising:
- an installation which generates a laser beam, said installation for generating the laser beam being arranged on a tablet-producing press and being connected to said tablet-producing press by a synchronization system;
- and
- a deflection system arranged on a die support of said tablet-producing press to deflect said laser beam onto the surface of the molded item or tablet.
A process for applying markings or break notches on molded items or tablets by treating a surface of a molded item or a tablet with a laser beam, said process comprising:
- deflecting said laser beam onto the side face of the molded item or tablet, said treatment being generally coterminous with ejection of said molded item or tablet from a die of a press, said treatment occurring when the molded item or tablet is ejected above the upper edge of the die by a lower punch.
A process for applying markings or break notches on molded items or tablets, comprising:
- treating a surface of a molded item or tablet with a laser beam, said treatment being generally coterminous with ejection of the molded item or tablet from a die of a press;
- wherein the shape of said marking or break notch is produced by a marking mask arranged in the path of the laser beam, said marking mask having openings in the shape of the desired marking or break notch.
