Abstract

A method of producing a film of plastic material, comprising the steps of passing a sheet of polymeric film material, of the type described, between and in temporary contact with two surfaces that form a pressurized contact line, at least one of said surfaces a mobile surface, and the material being at an elevated temperature, suitable for plasticizing it at least to a substantial degree as it approaches and enters the line of contact; maintaining the surfaces forming the contact line at temperatures suitable to convert the material, by cooling during its passage through the contact line, to a largely non-plasticized state, before or after leaving the contact line; and mechanically working the material during its transition from the plasticized to the non-plasticized state.
