Abstract
A method for coating yarn is proposed, including steps in which the yarn is first placed in contact with a dispersion of the coating agent in a dispersing agent or with the coating agent in melted form, optionally excess dispersion or melt is scraped back off the yarn, and then the coating is formed on the yarn, where in the case of the dispersion this occurs by means of at least partially removing the dispersing agent by heating, and the yarn thus coated is then cooled down and wound, which is distinguished by the fact that the coated yarn undergoes additional cooling before winding.
