Abstract

L'invention concerne une unité d'impression (300, 300A, 400, 400A, 800) pour une machine d'impression rotative, l'unité d'impression présentant des modules d'impression plats et empilables (100, 100A, 200) et au moins deux emplacements d'impression situés l'un au-dessus de l'autre. Les modules d'impression peuvent être desservis par le côté du cylindre d'encrage et du cylindre de poussée sans qu'il faille écarter les segments d'unité d'impression avec leurs raccordements, etc. L'application d'encre et d'eau sur une face entraîne par rapport aux unités aujourd'hui habituelles d'impression à caoutchouc-caoutchouc une division par deux de l'introduction d'humidité dans la bande (B, B1-B4) à imprimer. La structure modulaire de l'unité d'impression permet de configurer l'installation d'impression de manière très flexible et de la fabriquer de manière avantageuse. Dans la zone de l'unité d'impression, l'encombrement de l'installation d'impression est réduit d'environ 40 % par rapport aux unités d'impression H habituellement utilisées.
