ABSTRACT:
A device for treating at least one running multifilament yarn with compressed air contains one continuous yarn channel (13, 14, 15) which is circular in cross section. Into a cylindrical middle section (14) of the yarn channel (13, 14, 15) three blowing medium feed holes (16, 17) empty. The axes of these blowing medium feed holes (16, 17)intersect the axis of the yarn channel (13, 14, 15) at one common point each at an angle of 15.degree. to 40.degree.. With this device it is possible to treat multifilament yarn (M1) which is supplied to the yarn channel (13, 14, 15) with an excess delivery of 0 to 15% and which is discharged, transversely to the axis of the yarn channel (13, 14, 15), from the device such that the filaments of yarn are uniformly intertwined with one another over the length of the yarn and thus no protruding loops are formed.
