Roll coating is a common method in the manufacture of a wide variety of products. It is used to apply a thin liquid layer to a continuous flexible substrate. At low speeds, the flow is two-dimensional and steady; as the roll speed is raised, the two-dimensional flow is unstable and is replaced by a steady three-dimensional flow, which results in more or less regular stripes in the machine direction. This type of the instability is commonly called ribbing, it can limit the speed of the process if a smooth film is required as a final product. The liquids used in this process generaly are polimeric solutions, which present Non-Newtonian behavior. It was demonstrated, for Newtonian liquids, that the gradient of the pressure close to the meniscus destabilizes the flow, whereas the surface tension has a stabilizing effect. The critical parameter for the flow stability is the capillary number. For viscoelastic liquids can drastically change the nature of the flow near the free surfaces of the coating bead. The onset of the instabilities occurs at much lower capillary numbers than Newtonian flow case, which falls with the growth of the elasticity. Accurate theoretical predictions of the onset of ribbing when viscoelastic liquids are used is still not available. The mechanisms by which the liquid elasticity makes the flow unstable at Capillary numbers much lower than in the Newtonian case is not completely understood. Recent theoretical predictions have shown that at high Weissenberg number, the recirculation zone, present in the Newtonian flow completely disappears. In this work, film splitting flows between a stationary plate and rotating roll are analyzed experimentally by visualizing the free surface configuration and measuring the velocity field using the Particle Image Velocimetry (PIV) technique. Various solutions of low molecular weight polyethylene glycol (PEG) and high molecular weight polyethylene oxide (PEO) in water were used in order to evaluate the effect of mildly viscoelastic behavior on the flow. The goal was to confirm the theoretical predictions of Zevallos et al. (2004) on the effect of the liquid viscoelasticity on the streamline pattern and on the stability of the free surface with respect to three-dimensional disturbances.
