  • Patent number: 4965916
    Abstract: Interlacing means are provided for the interlacing of multifilament yarns exhibiting a yarn channel. At given distances from the entrance and exit openings forming the yarn channel, yarn guides are so arranged that, with the supply of compressed air shut off, the yarn is laid onto the yarn channel so that it extends parallel to its longitudinal direction, and that the straight yarn sections, which are located between the entrance and exit openings of the yarn channel and the yarn guides, are inclined at acute angles to portions of the geometric longitudinal axis of the yarn channel. Furthermore, the blow angle of the blow nozzle is smaller than 90.degree.. The length of the yarn channel equals for smooth yarns maximally 40 mm and for texturized yarns maximally 30 mm. There results exceptionally high yarn advance speeds and a particularly good vortexing of the yarn.
