<p>The frame, which includes transverse supports for the elastic mesh material, is made from angle iron, and to the vertical parts on its side are fitted spacers between which the end plates of the transverse supports are located. In the spacers and the frame are coaxial holes for scres, etc. for fixing for the frame in the sieving machine. The design leaves the entire sieve surface exposed and permits quick and easy mesh changeover.</p> |
