  • Apparatus for obtaining differential tangential variable speeds at different points of a deformable film
    Patent number: 5310106
    Abstract: This device is designed such that the differential tangential speeds V are variable at different points of a deformable flat film (1) or plate that moves along at least one drawing roller (3) rotating about an axis XX, said film (1) or plate moving in a direction perpendicular to the axis of rotation of the roller and resting on a generatrix G.sub.N of the roller. The roller (3) has a rotational speed N which is constant with time, while the distance G.sub.N C.sub.1 from the supporting generatrix G.sub.N of the film to the axis C.sub.1 of rotation of the roller is variable with time. The invention is applicable to the drawing of plastic films.

  • Method and device for the continuous stretching of a plastics material film
    Patent number: 4767578
    Abstract: The invention relates to a method for the continuous stretching of a plastics material film, of the type where the film is run off in engagement with two successive rollers which are driven at different tangential speeds, the second roller having a tangential speed which is greater than that of the first roller. The film is run off in engagement with at least a third roller, arranged downstream of the second roller and driven at a tangential speed which is greater than that of the second roller, and it is possible to select as required those of the three rollers in engagement with the film.
