Abstract
During the pneumatic holding of a yarn spun from fibers, the intensity of the air stream holding the yarn is changed to adapt to the prevailing working conditions. Such a change in intensity of this air stream can take place here in adaptation to different work phases and/or to the character of the held yarn. In order to reduce the intensity of the air stream, a secondary air stream may be fed to it at a point which is not reached by the yarn held by the air stream, or the cross-section of a pneumatic device conveying the air stream is changed. The pneumatic device is associated with an air control device which influences the intensity of the air stream and is connected to a control device which can be adjusted or programmed to take various working conditions into account. By means of the air control device an opening can be controlled through which the line can be connected to the atmosphere surrounding it. Alternatively, the air control device 9 can be provided with a choke which changes the cross-section of the pneumatic device.
