ABSTRACT:
Yarns are deposited on a conveyor belt in the form of random or ordered loops and are conducted through a yarn treating chamber. The treated yarn is drawn from the belt at a predetermined draw-off site. The position of the last yarn loop adjacent the draw-off site is scanned by a sensor, and the draw-off velocity is controlled as a function of deviations in the location of this last yarn loop. At the draw-off site a holding device is provided to press the looped yarn against the conveyor belt. During any interruptions of the drawing-off operation, the yarn will accumulate on the conveyor belt. The holding device and sensor are mounted to a slide which relocates the sensor and holding device downstream to a position in the vicinity of the last yarn loop so that the holding device will act on the yarn when the drawing-off operation is resumed. The holding device is then moved upstream along with the last yarn loop as the drawing-off operation proceeds.
