Abstract

L'invention concerne une unité d'application de vernis, intégrée dans une machine d'impression ou se présentant sous la forme d'une machine d'application de vernis séparée. L'invention vise à créer une unité d'application de vernis modulable, servant à appliquer des vernis de différentes épaisseurs, différents types et/ou différentes teintes. A cet effet, un système de dosage (8) constitué d'un cylindre tramé (6) et d'une racle à chambre (7) est placé en amont du cylindre d'application (5), et/ou au moins un système de dosage supplémentaire (10; 16) constitué d'un cylindre d'application supplémentaire (9; 13), d'un cylindre tramé supplémentaire (11, 14) et d'une racle à chambre supplémentaire (12; 15) est placé en amont du cylindre d'application (5).
