Abstract (en)
The present invention relates to a process for depositing a reserve of yarn of a tube without wound yarn in a rotor-spinning unit during the full bobbin doffing cycle, as well as to a device for carrying out such a process. The process according to the present invention substantially consists in lifting the pressure roller (2), disengaging it from the extraction roll (4) for the necessary time for forming some reserve windings, and in extracting the yarn (11), by supplying it with the necessary tension for it to exit the spinning unit (8) by means of the revolution supplied to the tube (22) on which, in a region close to one of its ends, the compact, fine string-like reserve of yarn is collected.
