ABSTRACT:
Air jets are normally designed for interlacing a particular size or type of multifilament yarns and are not normally designed for universal use in interlacing different types and sizes of yarns. The present interlacing air jet is provided with a rotationally adjustable air directing pin (27) provided with an air passageway (26) communicatively connecting an air entry passage (20) with a yarn processing bore (11) extending through the body (10) of the air jet. An annular groove (32) is also provided in the air directing pin (27) for directing air in semicircular paths of travel around the air directing pin (27). Rotational adjustment of the air directing pin (27) provides selective variation of the angle at which the air enters the yarn processing bore (11) and engages the yarn passing therethrough so that the air jet can be used to interlace different types and sizes of yarns.
