    摘要: An process for controlling the force exerted on a moving web of material, including a batten roller having an adjustable drive and a fixing roller having a pressure sensor. An amplifier is coupled between the pressure sensor and the adjustable drive. A web pulling device pulls the web in a downstream direction across the batten roller and the fixing roller. The pressure sensor generates a first signal representing the tensile force on the web as it passes the fixing roller. The first signal is amplified to provide a control signal to the drive for adjusting the speed of the batten roll.
