Abstract
The device has a guide body (1) with a through bore, which exhibits an outlet opening (3). A needle body contains a through yarn channel, which is coaxially aligned with the bore of guide body (1). One end of the needle body extends into a conical inlet section of the guide body bore and forms, with it, a passage gap for the blowing air. The blowing air is introduced by two feed bores (11, 12) into the annular space in front of the passage gap. An impact body (9) is placed in the area of outlet opening (3). A yarn (FT), coming from outlet opening (3), is deflected in front of impact body (9) from a median plane (M), which contains the axis of the guide body bore point (A) described by the intersection of a median plane (M), a plane (E) parallel to the axis of the guide body bore and perpendicular to plane (M) and located in such a way that the cross sectional areas of the medium feed bores on opposite sides of said plane (E) are equal, and a plane perpendicular to said axis and including the mouths by which the medium feed bores (11, 12) empty into an annular space in the conical inlet section (7). As a result the textured yarn becomes more compact and has only small uniformly distributed projecting loops.
