Abstract
A lickerin and feed mechanism create a supply of individual fibers 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 screen intercepts the stream of fibers and accumulates them into a web without the use of a high velocity 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. Multiple lickerins and feed mechanisms may be spaced along the conveying screen to create multiple-layer or blended products. The feed mechanisms may include devices for spraying particulate material on previously formed layers or blending it with fibers as a layer is formed.
