a coil 25 put on ', which protrudes upward through the associated Spinnriög 20 and serves that you through take up the associated rotor 17 fed yarn and wind it up. As is known, the spindles and Spools rotated continuously during the operation of each spinning machine 12, so that the yarn Y during the vertical Up and down movement of the respective ring rail 21 is wound onto the bobbins.

It should be noted that each of the elevated rails 30 has a separate traveling cleaning device could assign. In the following, however, only a single mobile cleaning device 10 is described. As an example, a mobile cleaning device 10 is shown in the drawings, as they are generally in Figures 19 through 22 of U.S. Patent 3,304,571 is described, to which reference is made here for further details. Generally speaking, includes mobile cleaning device 10 a wheeled ".. ' saw carriage 31 »whose wheels on rails of a guide 30 run; At least one of these wheels is normally driven by an electric motor 32, which with a suitable electromagnetic clutch 33 and an electromagnetic brake 34- is equipped, which on be controlled in a manner to be explained in order to move the mobile cleaning device 10 along the rail or of the track 30 to move at predetermined time intervals and bring them to a halt again, both after and before each work step to twist a broken thread. The platform 30 is with the usual ones Power supply rails 30a extending parallel to it are provided, which are connected to an electrical, not shown Connected to the power source. The power supply rails 30a and the contact brushes working together with them on the wheeled cleaning device 10 may be constructed and arranged to be used as in the U.S.A.

909881/1 1 U

U.S. Patent 2,184,880; therefore is likely to No further explanation is required at this point · However, it is important to note that the entire electrical Energy for the operation of the mobile cleaning device, the thread break counter and the turning devices 11 and 11 * is taken from these power supply rails 30a, which are arranged in an elevated position and supported by the track 30.

The carriage 31 also carries an electric motor 35 to Driving a fan 36, by means of which a negative pressure in a suction housing 40 and an overpressure is generated in a blower housing 41 arranged below; the two housings 40 and 41 are also supported by the carriage 31 or the electric motor 35.
