Abstract
A cascaded loop controller is used to control register or repeat lengths and web tension on laminating machines where the inner control loop utilizes register-length sensors near the unwind end of the laminating machine to make rapid adjustments in web tension that are necessary immediately following a reel splice and an outer control loop that provides a remote register-length set-point to the inner loop based upon a desired repeat length as measured near the rewind end of the laminating machine.
