Abstract
A cam mechanism for a folding cylinder or gripping cylinder of a printing machine have a cam disk assembly with two cam disks located adjacent to one another. The cam mechanism has good kinematic properties and is subject to low wear, the outer casing of the cam roller has two convex curvatures arranged adjacent to one another and running circumferentially around the cam roller, each curvature co-operating with one of the cam disks.
Claims19
A cam mechanism on a cylinder of a web-fed rotary printing machine, comprising:
- a cam disk assembly including first and second cam disks arranged coaxially, adjacent to one another and rotatable relative to one another;
- and
- a cam roller operatively connected to the cylinder of the web-fed rotary printing machine for running on said cam disk assembly during rotation of the cylinder, said cam roller having an outer casing with two convex curvatures arranged adjacent to one another for respectively cooperating with said first and second cam disks, said convex curvatures running circumferentially around said cam roller and defining a depression therebetween, said depression substantially aligned with a region between said first and second cam disks.
