Abstract

The subject of the invention is a process for continuously predrawing (prestretching) a packaging film, called extensible film 10, which is paid off from a braked roll of film and, after predrawing (prestretching) to a controlled width between predrawing (prestretching) rolls which are very close together and which width is wrapped, with a predetermined force, around merchandise 4 composed of items of merchandise and preferably supported on a rotating table 15. The main predrawing (prestretching) by acceleration in a set of mechanical rolls, of the extensible film is achieved in elongation stages which follow each other rapidly and which are distinctly mutually delimited 11, 12. <IMAGE>
