Air Jet Aggregate for an Air Jet Spinning Arrangement

Abstract

An air jet aggregate for an air jet spinning apparatus for producing a spun thread from a staple fiber strand includes a vortex chamber and a number of fluid-feeding injector channels running into the vortex chamber. At least two injector channels are provided, which have differing angles of inclination in relation to a parallel to the axis of the spun thread. The at least two injector channels having differing angles of inclination are connectable to at least one pressurized air source. The injector channels with differing angles of inclination are, preferably, connectable to separately adjustable pressurized air sources.
