Abstract

Un dispositif de commande de l'ouverture d'un encrier, ouverture définie par les interstices compris entre le rouleau d'encrier (105) et une série de lamelles (170) disposées côte à côte dans un plan et mobiles orthogonalement au rouleau, associe à chaque lamelle :
- un actuateur linéaire de positionnement (200) dont l'axe de mouvement (150) est relié au bord arrière de la lamelle par une pièce intermédiaire (160) et dont le carter à l'intérieur d'un module (140) est solidaire de l'encrier grâce à un bâti (130),
- des moyens de détection (220) d'une position de référence et de chaque mouvement de l'axe (150),
- des moyens de commande (215) agissant sur l'actuateur (200). A device for controlling the opening of an inkwell, an opening defined by the gaps between the ink roller (105) and a series of lamellae (170) arranged side by side in a plane and movable orthogonally to the roller, associated on each slat:
- a linear positioning actuator (200) whose movement axis (150) is connected to the rear edge of the strip by an intermediate piece (160) and whose casing inside a module (140) is integral inkwell thanks to a frame (130),
- means for detecting (220) a reference position and each movement of the axis (150),
- control means (215) acting on the actuator (200).
