ABSTRACT:
An apparatus is disclosed for simultaneously air jet entangling a plurality of advancing multifilament yarns. The apparatus includes a plurality of elongate air jet beams, with each beam having a longitudinal air passageway extending along its length, and at least one row of closely spaced air jet nozzle heads supported along each of the beams. Each of the nozzle heads includes a plurality of individual yarn entanglement nozzles and a central air chamber connecting the central air chamber to the air passageway. Also, an air jet aperture communicates between the air passageway and the yarn duct of each entanglement nozzle for directing an impinging airstream against an advancing yarn passing through the duct. The beams are mounted for adjustment on a supporting frame so that the nozzle heads may be positioned in proper alignment with a sheet of yarns passing therethrough. The beams may be rectangular or round in cross section and the nozzle heads are releasably connected along the length of the beams. An enclosure suction box surrounds the beams and removes the air exhausted from the entanglement jets and acts to insulate the noise of the entanglement jets.
