Abstract
1282176 Aspirator jets METALLGESELLSCHAFT AG 15 Aug 1969 [17 Aug 1968] 40894/69 Headings D1F and D1R [Also in Division F1] Filaments of thermoplastic material e.g. polyolefins, polyamides and polyesters are drawn off by means of an aspirator jet comprising a nozzle having a smoothly curved throat 16 with a funnel shaped inlet part 15 and an expanding outlet which forms an expansion chamber 17 for a primary aspirating gas. The primary gas is introduced under pressure through inlet conduit 11. A guide conduit 2 is centrally located in the throat 16 and extends through expansion chamber 17 and has an inlet port 3 for introduction of the filaments and secondary air which due to the influence of the primary aspirating gas reaches at least sonic velocity as it emerges from the orifice 19. The filaments and aspirating medium then pass through a draw-off conduit 18. The ratio of the open cross-sectional area of the end of the expansion chamber to that of the throat 16 is from 7:1 to 3:1. The expansion chamber may also be curvilinear in cross-section.
