  • compressed air thread splicing devices are used for connecting two or more threads.
  • the yarn ends to be joined are placed side by side in a Spieisshunt the Spieissvortechnisch and spliced together by means of one or more blasts of compressed air. This creates a nearly yarn-like Spieissharm.
  • EP-1 12'510 A2 teaches to add splashing air to the splicing air immediately before it is injected into the splitting chamber.

Abstract

L'invention concerne une buse (4) présentant une stabilité dimensionnelle mais élastiquement déformable, qui est disposée sur une embouchure d'un canal d'amenée d'air (3) d'un dispositif d'épissage par voie humide. La buse (4) est déformée provisoirement élastiquement par des forces extérieures, des dépôts de calcaire s'en détachant, si bien qu'il est possible de les éliminer. Une fois les forces faiblies, la buse (4) reprend sa forme initiale.
