ABSTRACT:
The invention relates to a screening machine having a multiplicity of mutually parallel transverse supports which are arranged transversely to the transport direction of the material being screened and on or between which a flexible screen plate is fastened. The transverse supports, which are movable relative to one another, of at least two movement systems are driven in such a way that mutually adjacent transverse supports alternately approach one another and move away from one another. The transverse supports move in separate, mutually parallel planes which are at an angle to the planes in which the transverse supports of one particular movement system are located.
