Abstract

A printing unit (100) for a printing press for web material is disclosed, comprising: a plate cylinder (2) mounted rotatably at ends (20) on two supports (1) mounted to slide horizontally on linear guides (5) integral with the sides (50) of the press structure, the plate cylinder (2) being designed to press against a drum (7) on which the web material to be printed runs; a roll (4) mounted rotatably at ends (20) on two supports (3) mounted to slide horizontally on linear guides (5), the roll (4) being designed to press against the plate cylinder (2) to transfer ink from the roll (4) to the plate cylinder (2); drive screws (6) operationally connected to the supports (1, 3) to drive them in translation; at least one handle (8) mounted in at least one of the supports (1, 3) that can be operated by the operator so as to uncouple said support (1, 3) both from the end (20) of the mandrel of the plate cylinder (2) or of the roll (4) and from the drive screw (6).

Description

technical field [0001] The invention relates to a printing unit for a web printing press. Background technique [0002] In known technology, printing presses comprise a plurality of printing units, by these printing units, the web material (web material) that needs to be printed is supplied, and this material can be paper, cardboard, self-adhesive paper, plastics, or composite layer Press roll material. [0003] Each printing unit is used to provide a color to the web material, and basically includes a set of three rollers, between which the web material (hereinafter also referred to as film for the sake of brevity) is supplied, and the color is transferred printed onto the web. [0004] The set of three rolls comprises in particular an ink roll or anilox roll which has on its surface a plurality of cells for holding ink. The anilox roller collects ink from a rubber roller dipped into a special pan, or directly from a container called a "doctor's blade" that fills the ink...
