ABSTRACT:
A false twist crimping machine is disclosed which is adapted for processing synthetic yarn, and which includes a novel means for the thermal treatment of a yarn at high processing speeds of 1,200 meters per minute and above, and without increasing the overall size of the machine. The yarn thermal treatment means includes a yarn heating plate and a yarn cooling plate. The yarn heating and cooling plates preferably each include a curved yarn path guideway to provide efficient and reliable yarn contact of the advancing yarn with the curved guiding surfaces, and at least the yarn cooling plate extends above a service aisle provided between the central frame of the false twist crimping machine and a yarn supply creel spaced from and extending parallel to the central frame. In one preferred embodiment, the yarn heating plate comprises two side-by-side vertically directed sections which are positioned near the floor next to the creel, with the yarn being guided serially along the two sections and then upwardly to the cooling plate which extends across and above the service aisle.
