ABSTRACT:
Tubes or conduits, guiding slubbing or roving or the like during pneumatic transport thereof, terminate at a box or cabinet which delimits a compartment connected with the suction side of a ventilator. Within the compartment there is provided for each tube an elongate delay space or chamber, through which pass the slubbing while supported by guide elements, whereas the slubbing-transport air flows off into the compartment by means of throughpass openings. Between outfeed or outlet openings, through which the slubbing departs from the box, and the delay spaces or chambers there are provided dam-up spaces through which there does not flow the transport air and into which there also cannot enter any ambient or outside air, since the band-outlet openings are closed by closure elements, typically pairs of rolls acting as sealing elements. The dam-up spaces permit a brief storage of the incoming slubbing or the like. The box has a tiltable cover, by means of which access to the interior of the box is afforded in order to draw-in the slubbing.
