Definitions

the invention relates to a nozzle for generating swirl in a nozzle spinning machine, as is known for example from EP-A-0321885.
a falling swirl air nozzle with a cylindrical, central bore and tangentially arranged air injection nozzles opening into it.
an inlet channel is used which has a smaller inner diameter than the central bore and its extension protrudes with a length into the cylindrical channel.
this document does not specifically mention - and is therefore considered to be more or less irrelevant - how the air injection nozzle opens into the duct.
a disadvantage of the swirl nozzle described is that it is constructed in two parts with the inlet channel and therefore requires a considerable additional outlay on mechanical processing.
the object of the invention is to provide a twist-generating nozzle which has a smooth, continuous channel, with or without gradations, the spinning results in terms of spinning tension and yarn tenacity being significantly better than in the case of conventional twist nozzles. This object is achieved by the features of patent claim 1.
a swirl nozzle 1 is shown purely schematically, which has a central cylindrical longitudinal channel 2, in which a tangentially arranged compressed air bore 3 opens.
the center line 4 of the longitudinal channel 2 and the center line 5 of the compressed air bore 3 form an obtuse angle ⁇ , which is generally between 120 ° and 150 °. However, this angle ⁇ is insignificant for the present invention.
Figures 2a and 2b show the arrangement shown in Fig. 1 in cross section. 2a clearly shows how the compressed air bore 3 opens into the longitudinal channel 2 in a perfectly tangential manner.
the center line 5 of the compressed air bore at the intersection with the inner wall of the longitudinal channel 2 forms an angle ⁇ with the tangent 6 on the longitudinal channel 2.
V ⁇ ⁇ cos ⁇ V ⁇ 1 ⁇ - V ⁇ 2 ⁇
V ⁇ is the volume flow and ⁇ the air density, which can be assumed to be constant.
