Abstract: An apparatus for washing freshly spun artificial yarn during its movement relates to the finishing of yarn such as viscose yarn. By this apparatus, yarn is intermittently saturated with a finishing solution on that portion of a rotating roll which extends outside the finishing solution contained in a tank. Between the saturation zones, the yarn is spaced apart from the roll surface for diffusion and squeezing of yarn. In order to ensure the intermittent saturation of yarn with the finishing solution, the yarn is displaced in the direction opposite to the rotational direction of the roll. An additional roller engages with the driven roller displacing the yarn so as to form a squeezing pair therewith, and there is an additional tank having a scraper. The scraper is in permanent contact with the roll surface below the zone of feeding the yarn thereto and is adapted to remove the layer of finishing solution from the roll surface.
