Abstract: A screen basket comprising a plurality of rods each positioned approximately parallel to the rotational symmetrical axis of the basket, a plurality of rings for connecting the plurality of rods, wherein the plurality of rods form screen slots therebetween, and wherein the plurality of rods is fastened to the plurality of rings by either welding or soldering. Each rod has a cross-section and each of said plurality of rings has a recess in the shape of the section of the cross-section of the plurality of rods. The recess is adapted to receive the plurality of rods therein.

Abstract: The breast box nozzle comprises a nozzle-type pulp stock duct formed by stream-guiding walls of the same width as the machine. The pulp stock duct is limited at its pulp stock discharge gap by a surface which extends over the width of the machine and is not touched by the pulp stock. Deposits in the area of the breast box nozzle which are caused by spray mists may cause defects in basis weight/cross section of the web being produced.The precipitation of the spray mist on the surface not touched by the pulp stock is prevented by a device which discharges a gaseous fluid into the space lying in front of this surface.
