Patent ID: 10960659

Abstract:
The invention describes a system (1) for overprinting on formats, comprising at least one printing unit (2), having first actuation means (14), and also comprising format supplying means (6, 7), format collecting means (9), at least one conveyor belt (5), second actuation means (10), and control means (11, 12, 13). The at least one printing unit (2) comprises at least one rotatable printing cylinder (3), having printing zones at the surface, and also first actuation means (14), configured to drive, in a controllable manner, the rotation of the printing cylinder (3). The format supplying means (6, 7) are configured to supply the system with one or more formats (4), each being intended to be overprinted in preset zones to be overprinted. The format collecting means (9) are configured to collect the one or more formats (8) once printed. The at least one conveyor belt (5) is configured to arrange, for the aforementioned one or more formats (4), an advancement path comprised between the format supplying means (6, 7) and the format collecting means (9). The advancement path passes through the printing unit (2). The second actuation means (10) are configured to drive, in a controllable manner, the advancement of the conveyor belt (4) along the advancement path, upstream of the printing unit (2) in the advancement direction. The control means (11, 12, 13) are configured to control, in a coordinated manner, both the first actuation means (14) and the second actuation means (10), so as to determine at each moment a correspondence of the preset zones to be overprinted of the format (4) with respective printing zones of the printing cylinder (3).
