Abstract (en)

[origin: EP1126058A2] The drive (2) for a rotating component (7), at an open-end spinning station, is a single motor drive system (2). The single motor drive is a step motor (2), to power a friction roller (3) which bears against the bobbin (7) to rotate it by friction contact directly or indirectly. Or the rotating component is a yarn take-off roller, between the spinner and the bobbin winder, with a single drive for a group of take-off rollers which covers only a small part of the workstations of the spinning machine. At the bobbin drive, with a friction roller (3), the acceleration phase on splicing increases the pressure between the friction roller (3) and the bobbin (7). The friction roller (3) has a surface character and/or structure to give the maximum force transfer to the bobbin. The diameter of the friction roller (3) is set so that, for the single motor drive system (2), an optimum combination is achieved of rotary speed and torque. When the wound bobbin (7) has reached the required diameter or the required yarn length has been wound, the bobbin (7) is braked by the motor drive (2). The single motor drive (2) has a selected direction of rotation. The rotary speed of the bobbin (7) is set according to the yarn tension. The yarn tension is registered according to the actual position of the yarn laying lever (5). The bobbin (7) rotary speed is controlled by the level of power fed to the drive motor or by an electronic control (6). A sensor (9) monitors the rotary speed of the bobbin (7) and/or its diameter.
