ABSTRACT:
A gravure printing machine cylinder has a means for mounting wrap-on gravure plates thereon using a tensioner able to be rocked about the shaft of the cylinder and having an outer cylindrical face in keeping with the outline of the cylinder in the printing condition. In order to be certain of a truly cylindrical outline of the wrap-on plate that is to be fixed on the cylinder, while at the same time decreasing the distance through which the plate is pulled when being mounted, the tensioner has a member with a beaked rim that is able to be rocked about an axis parallel to the cylinder axis separately from the tensioner, said beaked rim functioning with a gripping part in taking up and fixing in place the mounting fold or flap of the wrap-on plate.
