A PLANT FOR PRODUCING A WEB-SHAPED PRODUCT OF FIBRES AND POWDER

摘要

Plant (1) which, when running, forms - without the use of liquid - an air-la id web- formed product of fibres and powder (24) on a running endless forming wire (2) which is air-permeable and which operates mainly horizontally. The invention comprises a suction unit (5) (positioned under the forming wire (2)) and a forming head (8) (position ed above the forming wire (2)) with a perforated base (9) at the bottom; a fibre feed duct (11) to feed fibre by means of air flow from t he fibre source (10) and a powder feed duct (13) to feed powder by means of air flow from a powder source (12) into the forming head. The powder is added to the housing through a separate powder distributor (28) connected to the powder feed duct (12) from which the powde r is distributed evenly and homogeneously in the product.
