ABSTRACT:
A nozzle device for processing of synthetic yarns for intermingling or texturization. The nozzle device has a housing with an inlet end and an outlet end. The inlet end is located upstream in relation to the outlet end. An inner nozzle member is provided and has a conical outer wall portion and an essentially axial passage. An outer nozzle member is provided and has a conical inner wall portion. Both inner and outer nozzle members are kept in position within the housing. The conical outer wall section of the inner nozzle member and the inner wall portion of the outer nozzle member together form an outwardly conical gap having an upper or upstream end and a lower or downstream end. Inlet conduits or ducts are provided for passing a fluid into the housing and into a region thereof adjacent the upper end of the conical gap. The conical gap is defined by a generally annular cross-sectional area in any radial plane between the upper and the lower end of the gap. Structures are provided to form at least one flow-differential within the gap.
