Abstract

L'invention concerne une presse rotative (101) servant à imprimer une bande de matière (115), comprenant un cylindre central (102) et plusieurs dispositifs d'encrage (103-108) qui sont disposés autour du cylindre central (102) et dans chacun desquels de l'encre d'impression peut être transférée d'un cylindre d'impression (111) à la bande de matière (115). L'objectif de l'invention est d'accroître la rentabilité d'une presse rotative (101) pour l'impression d'emballages. À cet effet, les ancrages (114), côté machine, d'au moins un cylindre d'impression (111) sont conçus de sorte que le cylindre d'impression (111) peut être retiré pour libérer l'espace occupé par ce dernier (111) et permettre ainsi à une unité d'impression à jet d'encre (201) d'occuper cet espace.
