Abstract

Selon l'invention, un dispositif servant à ajuster l'écartement entre les cylindres d'une machine de pliage d'une presse rotative doit permettre d'ajuster de manière précise et reproductible l'écartement entre les cylindres. A cet effet, il est prévu une broche filetée rotative présentant des filets opposés, situés aux deux extrémités. Un mouvement à vis différentielle actionnable est associé à chacun des deux filets et chaque mouvement à vis différentielle agit par l'intermédiaire d'une butée sur une seconde extrémité d'un levier à deux bras, dont la première extrémité porte le cylindre de pliage.
