Abstract
A method includes passing a web of material over a deflector having a backstep, where the backstep causes the web to deflect towards the deflector. The method also includes capturing measurements of one or more characteristics associated with the web at one or more locations downstream of the backstep. In addition, the method includes identifying a cross direction (CD) profile of machine direction (MD) tension on the web using the measurements. The method could further include generating a Coanda airflow between the web and the deflector. The measurements could include pressure measurements identifying air pressures in a space between the web and the deflector and/or deflection distance measurements identifying distances by which the web is deflected towards the deflector.
