Abstract: The present invention relates to a process and device for knotting a yarn on a package. The process consists essentially in gripping the end (3) of the yarn and positioning the yarn under tension in prolongation of the last wound turn, in producing a slack loop parallel to the end (3) of the tensioned yarn, then in forming a twist by twisting a length of the slack loop with end (3) of the tensioned yarn, in then tightening the obtained twist on the package (1) and in cutting the remaining end of the yarn. The invention is more particularly applicable in the field of the textile industry, in particularly for the winding of yarns and particularly knotting an end of the yarn on a package.
