Direct Drive Motors Improve Flexographic Printing Performance
Recent work done by Kollmorgen—a global leader in manufacturing motor and motion solutions—has shown that it is possible to synchronize components within the flexo printing process without mechanical transmission by using closed loop control technology. This synchronization is key to managing web tension throughout the process while ensuring a steady repeat length.
