Abstract: An assembly (15) for pretreating at least one object (5) intended to be printed with at least one ink, the assembly including a frame (34), and at least one pretreatment unit (36) suitable for applying, on a surface (7) of the object, at least one ink adhesion promoter, and obtaining a coated surface (7). The assembly comprises a wiping unit (38) suitable for wiping the coated surface (7) in order to obtain an at least partially wiped surface, the object being in a wiping position in which it is situated across from the wiping unit.

Abstract: A printing machine including a calibration bezel. The calibration bezel includes a central opening coaxial to the axis of rotation of the core such that an object to be printed passes through the central opening before being printed by the printing station. The calibration bezel includes moving elements movable between a tightened position in which the central opening is small, and a loose position in which the central opening is large, and means for moving the movable moving elements between the positions so that the calibration bezel is in the tightened position when an object is transferred from the transport means to the printing station at least until the central opening is crossed by one end of the object and in the loose position when an object is transferred from the transport means to the printing station.

Abstract: A doctor blade support (2) for a machine for printing paste by silk screen printing, includes: a doctor blade (6) of substantially square cross-section which is to come into contact with the meshes of a silk screen printing screen in order to apply the paste to an element to be printed; a first (12) and a second (14) clamping jaws suitable for clamping the doctor blade (6); at least two elements (20) for tightening the first clamping jaw (12) towards the second clamping jaw (14) in order to clamp or withdraw the doctor blade (6); characterized in that each tightening element (20) includes a resilient element (40) applying a force between the two clamping jaws (12, 14) in order to move them towards each other, and elements for regulating the deformation of the resilient element (40).

Abstract: A printing machine including a plate adapted to rotate about its axis and carrying at its periphery a plurality of object supports having a top face which receives an object to be printed and workstations distributed circumferentially around the plate in line with the trajectory of the object supports, some of which are printing stations and others of which are treatment stations. At least one of the object supports includes a lifting system which raises the object relative to the top face of the object support. The lifting system is connected to a suction head which preserves the projecting position of the object corresponding to that it initially occupied on the object support. The lifting system preferably includes at least two tubes which slide through holes through the object support and the plate.
