Abstract: A machine for making a mixed yarn by combining two false-twist textured yarns is disclosed. The machine comprises drawing systems (3A, 3B; 8A, 8B) arranged on either side of the texturing area and mounted alternately on two separately controlled parallel, shafts, and heat treatment units (5A, 5B) located in the false twisting area and having a temperature controlled by two mutually separated systems. The false-twist spindles (7) are power spindles with a speed that may be varied to suit each kind of yarn. The machine comprises joining device (9) for interlacing two yarns from two different texturing positions, the device being arranged, when seen from the front, between the positions so that the two yarns (2A, 2B) follow identical paths before being joined.

Abstract: The invention concerns a false-twist texturizing machine of the type in which the heater, the cooling zone and the false-twist spindle are in substantially straight alignment and arranged at least in part above the service zone. The machine of the invention is characterized by the fact that the heating device, arranged upstream of the spindle at the upper part of the machine, is an open heater and that the machine includes means for lacing up and guiding the yarn between the first yarn feeder and the entry point of the heating device.

Abstract: A false-twist texturing spindle in which the yarn to be twisted may be automatically threaded in the spindle through a retractable tube that is longitudinally movable between the rollers or discs of the spindle, on an axis coincident with the axis of thread travel. The retractable tube is movable from an inoperative spindle mode, allowing yarn threading, to an operative spindle mode after threading, for yarn twisting.

Abstract: A yarn texturizing machine in which there are provided a plurality of treatment positions, each position having therein a substantially T-shaped framework having a vertical portion and a horizontal portion. Each framework has associated therewith, two false twisting arrangements, each including, in operational sequence, a yarn supply device, a first yarn feeder, a yarn heating device, a cooling zone for the heated yarn, a false twist spindle, a second yarn feeder and a wind-up device. The two false-twist spindles, the two second feeders and the two wind-up devices are each mounted on the vertical portion of the T-shaped framework and the remaining components, that is to say the first feeder, the heating device and the cooling device for each spindle are mounted on one of the horizontal portions.
