Fremgangsmåde og indretning til fremstilling af en spinde-fiberdug

摘要

In a process to produce spun-bonded fleece from endless filaments, a proportion of the filaments are naturally crinkled or curled. The filaments are deposited on a moving conveyer that advances towards a bonding station. The bonding station consists of an overhead hot gas blower directed at the fleece fibres. The fibres are deposited essentially in parallel array in-line with the direction of travel. The filament curl is generated either before or after deposit on the conveyer. Further claimed is a commensurate fleece production and bonding unit.
