Abstract

A process for the removal of films of flow agent from moving strip material, by squeezing away the film by means of squeeze rollers and an air flow duct which each extend transversely with respect to the forward feed direction of the strip material. The air flow is directed along the squeezed-away cushion of flow agent, and entrains the cushion of flow agent. Apparatus which is used in the process includes air flow ducts which extend transversely with respect to the forward feed direction of the strip material, and which are positioned at the point of entry of the strip material into the squeeze region.
