Abstract

The novel technique is used to measure the pressure profile of a thin viscous film (i.e. coating suspension) in the nip between a soft viscoelastic roll and a smooth metal rod. We have studied the influence of the components, the solids content and the viscosity of the coating suspension on the measured nip pressure profile during different process conditions.
