ABSTRACT:
An apparatus for measuring the dynamic contact angle of a coating on a discrete web segment includes a rotatable coating wheel around which the web segment is mounted and a syringe which produces a coating bead having no edge bead. The interface between the coating and the web is viewed in a plane parallel to the axis and the surface of the coating wheel and the contact angle is measured.
