  • the recess designed as a circular bore can be produced in a simple manner. Such a recess is particularly advantageous for cylinders with a face ring arranged on the face side, since for the face ring no additional operations for additional bushings, such as slots, are required in addition to the bore.

Abstract

Afin d'ajuster le registre latéral des planches d'impression (02) montées par serrage sur un cylindre (01) de rotative, l'invention vise à mettre au point un dispositif d'ajustement fonctionnant de manière simple et fiable. Selon l'invention, il est prévu à cet effet qu'une broche de réglage (14) porte dans sa zone terminale (19) éloignée des faces d'about du cylindre, un disque de registre (21) adapté au contour de l'alésage du cylindre (07), ledit disque entrant dans une cavité des branches suspendues (03,04) de la planche d'impression (02).
