PROCESS AND APPARATUS FOR CONTINUOUS MANIFACTURING STONE WOOL VEIL LAP |
摘要 |
In the continuous production of mineral wool nonwoven fabrics, fiber/gas/air mixtures (3, 4) produced by several shredding units (14 to 17) are directed onto collecting conveyor units (19, 21) with suction surfaces (c, d) running in a curve and being under suction pressure for the formation of a wool nonwoven fabric (25). In this case the arrangement is such that an imaginary suction surface, increasing in its size in the conveying direction, is assigned to each fiber/gas/air mixture formed by the individual shredding units (14 to 17), actually d is larger than c. As a result it is possible, in a space-saving method of construction and per collecting conveyor unit to produce mineral wool nonwoven fabrics from rock wool with constant suction pressure with bulk densities even under 25 kg/m3 in good product quality. By series connection of several units or an oscillating deposit of an individual nonwoven fabric multilayer felt webs can further be formed. |
