<p>TRAVELING PNEUMATIC CLEANER AND AUTOMATIC UNLOADING ARRANGEMENT AND METHOD A plurality of traveling pneumatic cleaners for respective groups of textile machines cooperate with respective unloading stations for transferring fiber waste from collection chambers of the traveling cleaners into the unloading stations. All the unloading stations are connected, via normally closed valves, to a common source of suction, and according to the method and apparatus of this invention, provision is made for controlling the opening of the valves fox the respective unloading stations so that only a single one of the valves may be opened at any given interval of time, thus minimizing the amount of suction required at the source for effectively transferring the fiber waste into the unloading stations. Further, a normally closed door for the collection chamber or chambers of each traveling cleaner is controlled so that the opening of each such door may be effected only at times when the valve of the respective unloading station is open.</p> |
