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.
