Abstract: The method and corresponding device of yarn braking are provided by means of an attending device provided with a vacuum tube into which the end of the yarn is sucked in before commencement of braking. At drawing off from the vacuum tube, the yarn is braked between the braking surfaces of a stationary brake friction member and a moving brake friction member, which are arranged on the attending device displaceably to the track of the yarn. For generating the braking force, the moving brake friction member moves towards the stationary brake friction member and fits against it at a contact abscissa or a contact surface.

Abstract: The inventions relates to the method of yarn braking especially at renewal of spinning in a working position of an air jet spinning machine by means of attending a device provided with a vacuum tube (2), into which before commencement of braking there is the end of the yarn (100) sucked in, which at drawing off from the vacuum tube (2) is braked between the braking surfaces of a stationary brake friction member (50) and a moving brake friction member (30), which are arranged on the attending device displaceably to the track of the yarn (100), while for generating the braking force the moving brake friction member (30) moves towards the stationary brake friction member (50) and it fits against it at a contact abscissa (301) or a contact surface (302).
