Drive Upgrade for Web Based Machine

Printing machines have a long service life. Shaft-free design and Siemens synchronized drive technology make it particularly easy to adapt installed presses to new design. For example, new printing units can be added, without any major conversion, because existing power trains can be used as they are. That saves time and considerably reduces costs.

One typical example of printing machine retrofit is the expansion shafted or shaftless presses while existing mechanical line shafts do not need to be modified. MASTERDRIVE MC drive system allows the simple expansion of shafted and shaftless presses.

Drive retrofit in mixed operation of a "real master axis" with a shafted press (scheme on the left) or operation purely with an "electrical shaft" (scheme on the right).

This retrofit concept of developing hybrid configuration allows adding or replacing the web in one printing unit using free-standing web components (i.e. slitter, sheeter, etc.) without disturbing the other printing units, or compromising the overall web performance.

In addition, it affords system designers the luxury of being able to pick and choose how much of the mechanical line shaft they want to eliminate in the overall system.
