Abstract (en)

[origin: EP0340863A1] The present invention relates to a yarn-tensioning runner (3, 7) for the formation of a reserve of yarn of a tube (22) without wound yarn in a rotor-spinning unit (8) during the full bobbin, doffing cycle, and said runner is constrained, as a single body, to the end of a lever (10) of an unit (10, 15) suitable for guiding the winding of some turns of yarn on a limited area, close to an end of said tube. Said yarn-tensioning runner is provided with a yarn-tensioner load element (3) activated by a force of electromagnetic nature, or by the elastic force of a spring, or by a force generated by the pressure of a fluid, all of said forces being adjustable by using means known from the prior art.
