ABSTRACT:
A sensor for detecting directional variations in a physical characteristic of a moving sheet of material is disclosed. The sensor has a support for supporting the moving sheet. The support defines an open region into which the moving sheet is deflected by a deflector. Detectors coupled to the support detect and produce signals indicative of the force exerted on the support by the deflected sheet in at least three different directions. Each signal is processed to determine a physical characteristic, such as extensional stiffness, of the sheet of material in each of the three directions. The directional variations of the physical characteristic may be used to determine the fiber orientation angle and the degree of anisotropism of the sheet.
