Abstract

A multi-color web-fed rotary printing press is arranged having a plurality of printing groups with each group having several individual printing units. Each printing group has an upright drive shaft that is connected to a drive motor for each of the several printing units in the group. The several upright drive shafts are connected to a longitudinal main drive shaft. The individual drive motors and the upright shafts are sized to be able to take over the drive of one of the printing units in a printing group should its motor fail.

Claims

1. A drive for a multi-color web-fed rotary printing press comprising:

a plurality of printing groups with each of said printing groups having at least two individual printing units disposed one above the other;

an individual printing unit drive motor for each one of said individual printing units in each one of said plurality of printing groups;

at least first and second folding units, each having a separate folding unit drive motor;

a separate upright shaft positioned adjacent each one of said plurality of printing groups and each of said at least first and second folding units, each said upright shaft having an upright shaft clutch;

a separate coupling clutch and bevel gear connecting each individual printing unit in each one of said plurality of printing groups to said separate upright shaft associated with said one of said plurality of printing groups; and

a main synchronizing drive shaft extending longitudinally and being connected to each one of said upright shafts for said plurality of printing groups and said at least first and second folding units through said shaft clutches, each of said individual printing unit drive motors being separately disconnectable from its associated one of said upright shafts, each said individual printing unit drive motor having an output sufficient to operate another one of said printing units in the one of said printing groups in which it is located upon failure of another one of said individual printing unit drive motors in the one of said printing groups in which said individual printing units are located.
