Title: Compressed air distributor self twist product - with rotating perforated cylinder periodically supplying twisting-jet nozzles
Inventor: MOVSHOVICH P M
IPC: D02G3/28
Filed: 1976-08-17
Abstract: Distributing device supplies compressed air to the jet nozzles of the swirl chambers of an appts. making a self twisted product. Device has a hollow housing with a compressed air supply passage in it. Apertures in the housing join with the jet nozzles of the swirl chambers. A rotary cylindrical distributing member is positioned inside the hollow space of the housing with the gap between its surface and the housing. Cylinder is shaped as a sleeve with a bottom, a cylindrical wall and an open end facing the compressed air passageway. Passages in the cylindrical wall of the rotating member join periodically with the jet nozzles of the swirl chambers to supply the compressed air. Gap between the housing and cylindrical wall is selected to pass less compressed air than the passages of the distributing member. One end of the housing is in the form of a lid through which the compressed air passageway passes. Device is of simple construction and of reliable operation that keeps the prodn. process stable and prevents variation of the self twisted prodn. resulting from loss of efficiency of air distribution because of wear.
