Abstract

A method of producing a large area of cold-stretchable thermoplastic polymer in the form of a sheet or tape, in which a hot-melt film of the material is introduced through a mouth device between cooperating elements of which therefore minus one is a roll at a temperature below the melting point of the polymer, characterized in that the mouth device is such that it produces cuts in the film between the two surfaces of the film, and includes a device for producing grooves so less on one of these surfaces.
