Jet for interlacing textile yarns

摘要

An air interlacing jet 2 includes a yarn channel 20 and a threading slot 42 forming an opening on one side of the yarn channel so that yarn or yarn filaments can be inserted into the yarn channel. An air orifice 40 intersects the yarn channel and high pressure air injected through the air inlet or orifice 40 interlaces or intertwines the yarn or yarn filaments as they are drawn through the yarn channel 20. The body 4 of the interlacing jet or jet insert 2 is a single piece member and the yarn channel 20 includes outwardly tapered sections 28 and 32 at each end. The tapered sections are formed by an EDM process. Thread guides 58, 60 located below the yarn channel axis and the tapered yarn channel sections permit the yarn to be drawn through the yarn channel 20 at an angle relative to the threading slot 42 so that the yarn cannot easily escape from the yarn channel 20. The air jets or jet inserts 2 can be positioned side by side in abutting relationship so that the jets can be positioned in close proximity to decrease the centerline spacing for adjacent yarns.
