发明名称 Apparatus for manufacturing spun-bonded webs
摘要 The invention relates to a device for manufacturing spun-bonded webs with a nozzle arrangement which spins out warps of yarns. The device according to the invention has a longitudinally-extended duct for generating a gas current which transports the yarns in the duct, and a depositing chamber with an air-permeable deposit belt for deposition of the yarns. The deposit chamber (9) surrounds the conveyor belt (2) in the deposition area of the yarns, and is in the form of a gas-tight casing (9), the width of which is greater than the width of the deposit belt. By means of the casing, a greater degree of vacuum may be used to generate the gas current, and thus the yarns are more intensively drawn. Furthermore, undesirable turbulence of the yarns at the edges of the deposit belt is reduced, and an improvement is achieved in the web structure in these areas.
