Abstract

L'invention concerne un dispositif de transport et de montage (1) pour un ou plusieurs ensembles de cylindres (2, 3) formant des jeux de rouleaux complets, qui se composent essentiellement d'une douille d'emballage extérieure (4) et d'une douille d'emballage intérieure (5) entre lesquelles sont disposés les cylindres (2, 3) disposés les uns à côté des autres sur un cercle partiel commun et se touchant par leurs enveloppes, avec des moyens (6) destinés à fixer la position axiale des cylindres (2, 3) dans leur position de transport. Selon l'invention, les moyens (6) destinés à fixer la position axiale des cylindres (2, 3) sont constitués d'un sertissage marginal (8) périphérique, tourné vers l'intérieur, qui est formé sur l'un des côtés axiaux (7) de la douille d'emballage extérieure (4), ainsi que d'un sertissage marginal (10) périphérique, tourné vers l'extérieur, qui est formé sur l'autre côté axial (9) de la douille d'emballage intérieure (5).
