Abstract: For the production of spunbonded fabrics there is given a process consisting in that monocomponent or bicomponent fibers are spun from multiline longitudinal spinning nozzles mounted in rows on double spinning beams in such a way that the emerging filament rovings overlap over the entire production width, that, before depositing, the filament rovings are cooled by transverse blowing from one side and by sucking-off on their other side freed from spinning vapors, mechanically and/or aerodynamically stretched and deposited to the web.The apparatus described comprises double spinning beams with a length of 800 to 8,000 mm which carry multiline longitudinal spinning nozzles staggered to one another with high hole numbers, with lengths of the individual nozzles from 500 to 700 mm.
