A method for introducing yarn into a pneumatic yarn texturizing means, in which the yarn is positioned across the inlet orifice of the texturizing means, a stream of fluid is forced against the yarn to introduce it into the orifice in the form of a loop and a yarn cutting device, located downstream of the orifice in the direction of movement of the yarn, is actuated, its operation being synchronized with that of the fluid stream.

Device for introducing a yarn into a pneumatic yarn texturizing means

Multifilament yarn is interlaced by passing the yarn through an apparatus which impinges four streams or jets of fluid upon the yarn. The jets or streams of fluid are given a rotational component by auxiliary streams of air which impinge on the jets or streams with a tangential attitude. The yarn and impinging streams of fluid converge in a cavity located within an interlacing chamber wherein the height of the cavity is no greater than the smallest diameter of the cavity and wherein the inlet of the interlacing chamber is wider than the diameter of the cavity and the outlet of the interlacing chamber is narrower than the cavity.
