<p>An apparatus for effecting intermingling of individual filaments in a running yarn by the action of two or more fluid jets comprises a chamber (5) extending longitudinally through a body shell (2), the chamber being defined by a horizontal planar first wall portion (6) and a bent or curved second wall portion (7) which is symmetrical about a vertical plane extending longitudinally through the middle of the first wall portion. Fluid jet nozzles (9a,9b) positioned symmetrically in the second wall portion provide air jets which combine as a compound jet which forces a yarn down towards the first wall portion (6), causing intermingling of the filaments. Because of the symmetry of the chamber and air jets continuous unidirectional rotation of the yarn is minimised so that a high degree of uniform intermingling is achieved for a minimal air flow. The apparatus can be an assembly of three wall pieces, (2a, 2b, 2c), the first wall portion (6) of the chamber being a ceramic surface to resist abrasion by the yarn and airflows, and a longitudinal slit (13) can provided to facilitate introduction and removal of the yarn. </p> |
