Quality Printing--Handling it Right

To broaden the range of materials that can be run with its products, ABB has developed its newest line of web tension load cells. According to Sarnelli, typical tension systems have a 10 to 1 tension application range, but ABB's new load cell can achieve a 30 to 1 ratio.

ABB has also developed a variable frequency AC drive motor brake as an alternative to friction brakes on unwind stands. "A motor brake has a far wider operating range than a friction brake and offers far better control, especially when the substrates get thin and light weight," says Sarnelli.
