ABSTRACT:
A cylinder, for example a lickerin, and feed mechanism create a supply of individual fibers, for example pulp, which follow the rotation of the lickerin. These fibers are deflected from the lickerin in the form of a stream by means of a plate arranged parallel to the lickerin. A conveying screens intercepts the stream of fibers and accumulates them into a web without the use of a high pressure stream of air to doff the fibers from the lickerin or to capture fibers on the conveyor. Further, the housing for the apparatus is opened so that there are no seals to compress the web after it is produced. A feed tray located next to the lickerin can be used to include other particulate materials (fiber or granules) in the main fiber stream and a tapering of the deflector plate can separate the component of the blended fiber-particulate material stream into layers in the resulting web distinguished by particle weight.
