Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus for producing a spunbonded nonwoven fabric 1 from aerodynamically stretched filaments composed of a thermoplastic synthetic substance, provided with a spinning head 2 having a plurality of spinning orifices, discharging a curtainlike material 3 composed of the thermoplastic filaments from the spinning head 2, a stretching nozzle 5 having two oppositely located stretching nozzle mechanical units 6 forming a nozzle gap and capable of producing the spunbonded nonwoven fabric 1 a narrow weight per unit area tolerance. SOLUTION: At least one temperature regulating apparatus is connected to at least the one stretching nozzle mechanical unit 6 in order to regulate temperature of the stretching nozzle mechanical unit 6.
