Abstract: A process and appts. are claimed to develop a wet felting material from fibres in a suspension, with a moving mesh drawing the wet fibres at an angle out of the suspension tank for suction units under the mesh to extract the water. The fibres, in the felting material, then travel without help of additional feed units to a drying surface located under the mesh level. The system dispenses with the need for a pick-up felt to transfer the material from the water-extraction mesh to the drying station, where moisture from the fibres would build up in the pick-up felt and progressively increase the drying action needed for the fibres. The process is designed for the use of a suspension of fibres of cellulose, rayon, fibrides of polyethylene or polystyrene, fibres of polyamides, polyesters, polyacrylnitrile, PVC, glass, asbestos and their mixts.
