Abstract

Procedure for manufacturing a film, predominantly mono-axially oriented, of a thermoplastic material, capable of extrusion through an annular film die, expelling a tube of thermoplastic material above its melting temperature, inflating said tube by a gas, partially cooling it with an externally blown gas, maintaining the required diameter by means of at least one internal mandrel and/or one external mandrel, crushing it in a flat tube and stretching it outwards, characterized in that said film is spirally stretched making contacting at least one mandrel between the die element and the drawing element, while either the die or the pinch roller continuously rotate in one direction at a constant number of revolutions per minute, while the other elements in contact with the film have a rotary movement of the same or different angular velocity as The die or pinch roller alternately remains stationary.
