Beschreibung
Zusammenfassung:	PURPOSE: Provided is an improved apparatus for producing a nonwoven web and, more particularly, a spunbond web with reduced weight per unit area from thermoplastic filament. CONSTITUTION: An apparatus for producing a spunbond web from aerodynamically stretched thermoplastic synthetic resin filaments, is characterized by comprising: a spinning head for producing a curtain of thermoplastic synthetic resin filaments; a stretching nozzle defined between a pair of nozzle-forming units receiving the curtain of filaments and aerodynamically stretching the filaments; a foraminous belt collecting aerodynamically stretched filaments in the form of a spunbond web; and at least one temperature control device for controlling the temperature of at least one of the units to reduce basis weight tolerances in the web. 본 발명은 공기 역학적으로 연신되는 열가소성 플라스틱제 필라멘트로 스펀본드 웨브(spunbonded web)를 제조하는 제조 장치에 관한 것으로, 다수의 방사 노즐 구멍이 있는 방사 헤드를 구비하며, 그 방사 노즐 구멍으로부터 열가소성 필라멘트로 이루어진 커튼이 방출된다. 노즐 갭을 형성하는 2개의 대향된 연신 노즐 유닛을 구비한 연신 노즐이 마련되어 있다. 하나 이상의 연신 노즐 유닛에는 그 연신 노즐 유닛의 템퍼링을 위한 하나 이상의 템퍼링 장치가 접속되어 있다.
