Abstract

Method for holding, tensioning or controlling the position of films and tubes of uninterrupted plastic material, characterized in that the moving film or tube is supported, at least on one side, practically out of contact with solid surfaces, by a pillow of gas to which a gas is positively and restrictively supplied, which in this way can exert a restoring force on the film or tube if these are displaced towards the gas pillow, such that the position of the film or tube is controlled the film or tube being maintained against the gas pillow, at least partially, by means of effective gas pressure.
