Abstract
A method and apparatus are disclosed for automatically centering running lengths of strip material of different widths. The strip material is passed between an elongated air source and an elongated pressure pickup device. Depending on whether and in which way the strip moves laterally off center a conductive diaphragm located within a sensing device is deflected by a differential air pressure causing electric and hydraulic control circuits to adjust a steering roll thereby continuously and automatically centering the strip material.
