Abstract: A machine and a method for producing chenille yarns is provided; the machine comprises yarn-forming parts and spooling parts directly downstream disposed, and an apparatus for controlling the quality of yarns located between the yarn-forming parts and the spooling parts.

Abstract: Apparatus for driving interweaving threads in a yarn-forming unit of a chenille machine comprising, for each of the two sides of a gauge (1) on which the fuzzy thread is wound and sized, a pair of rollers (3, 30) forming a calender for driving two interweaving threads to be twisted in order to engage the lengths of the fuzzy thread. Of the rollers (3, 30), the upper one (3) of at least one of the two pairs is provided with a plurality of radial channels (31) associated to air-suction device to pull in the lengths of fuzzy threads being cut by a blade (2) towards the respective edge, at least over an arc thereof instantaneously facing the gauge (1) during the rotation of the rollers (3, 30) of the pair.
