Abstract
Abstract An improvement in an apparatus for commingling individual filaments in multifilament yarn is disclosed. The prior art commingling jet is a body having a gas passageway intersecting with a yarn passageway. The improvement is using a noncircular orifice near the exit of the gas passageway at the intersection of the gas passageway with the yarn passageway so that gas issues from the noncircular orifice to impinge on any yarn present in the yarn passageway.

Claim 1
Independent Claim
75 words
In an apparatus for commingling individUal filaments in a multifilament yarn comprising a body having a yarn passageway and a gas passageway intersecting with said yarn passageway the improvement comprising said gas passageway having a noncircular orifice near said intersection with said yarn passageway, said noncircular orifice having a V-shaped cross-section with an arc opposite the apex, so that gas issues from said noncircular orifice to impinge on any yarn present in said yarn passageway.
Claim 2
Dependent Claim
75 words
In an apparatus for commingling individUal filaments in a multifilament yarn comprising a body having a yarn passageway and a gas passageway intersecting with said yarn passageway the improvement comprising said gas passageway having a noncircular orifice near said intersection with said yarn passageway, said noncircular orifice having a V-shaped cross-section with an arc opposite the apex, so that gas issues from said noncircular orifice to impinge on any yarn present in said yarn passageway.
Claim 3
Dependent Claim
139 words
In an apparatus for commingling individual filaments in a multifilament yarn comprising a body having a yarn passageway made up of an inlet passageway and an outlet passageway said inlet having a larger diameter than said outlet, said inlet and outlet being directly aligned on the same axis, said body having a gas passageway intersecting said yarn passageway at the junction of said inlet and said outlet at an angle of between about 15* to about 75* as measured between the axis of said gas passageway and said outlet yarn passageway, the improvement comprising said gas passageway having a noncircular orifice near said intersection with said yarn passageway, said noncircular orifice having a V-shaped cross-section with an arc opposite the apex, so that gas issues from said noncircular orifice to impinge on any yarn present in said yarn passageway.
