Abstract: Supply system (10) for a silk-screen printing machine comprising a supply table (20) mobile on longitudinal guides (22) in a longitudinal advancing direction (F) of a sheet (12) able to be registered longitudinally through longitudinal registering means (60), the supply system (10) comprising transversal registering means (40) which comprise locking means (50) suitable for locking the sheet (12) on the supply table (20) for a predetermined time and an actuator (24) to move the supply table (20) in a direction transversal to the longitudinal direction (F) such as to allow the registering of the transversal position of the sheet (12) without misaligning it with respect to the longitudinal direction (F).

Abstract: A silk-screen printing machine in simplified register comprising a bearer structure (12) on which a silk-screen printing frame is arranged, elements in register (18) of the position of a sheet element to be printed (15) in a supply plane (14), means (34) for detecting the position of the sheet in register (15) and at least one pincer-carrying rod (16) suitable for pulling the sheet (15) on a printing plane (13), is equipped with a group for registering the sheet (15), which is arranged upstream of the pincer-carrying rod (16) and comprises a transversal plate (17) for supporting the sheet and able to translate towards the pincer-carrying rod (16), a plurality of the mobile elements in register (18) suitable for interacting downstream of the plate (17) with the supply plane (14) of the sheet and a plurality of presser elements (19) arranged in a position above the support plate (17) and mobile towards it to engage the sheet (15).

Abstract: A machine for printing on flat supports of a type equipped with one or more printing heads (12) fed by respective ink reservoirs (13), where the printing heads (12) are supported by a device (14) movable in at least two perpendicular directions. In this printing machine (10), the printing heads (12) are associated with at least one ultraviolet lamp (UV) (20, 21) also movable by the device (14).
