摘要： 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). To generate the braking force on the moving brake friction member (30) the action force in the loading point (Y) and the reaction force in the stop point (X) is acting, whereas one of these points is to be found at the end of the moving brake friction member (30) lying opposite to the contact abscissa (301) or the contact surface (302) and the second is lying between this member and the contact abscissa (301) or the contact surface (302), while the action force is generated by means of the control member (4) and the reaction force is generated by means of the stop (6), against which the moving brake friction member (30) leans, so that the braking surface of the moving brake friction member (30) always abuts against the braking surface of the stationary brake friction member (5) along the whole length of their contact abscissa (301) or contact surface (302).The inventions also relates to the corresponding device.

摘要： 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.
