Abstract
A screening machine with two driven systems driven in circular oscillation by means of at least one eccentric shaft. The shaft is mounted on both frames simultaneously which are separated from one another and each of the frames comprises a plurality of crossmembers fastened parallel to one another to the respective pair of uprights. The crossmembers of the respective frames, lying in a respective screening plane, alternate with one another and are driven by the systems in a way resulting in a stretching and contracting motion of an elastic screen fastened to the crossmembers and, consequently, the screen material is cast from the surface of the screen.
