ABSTRACT:
First suction forces of relatively large magnitude and small duration, and second suction forces of relatively small magnitude and large duration, are alternatively applied to the trash outlet of each trash box of a multi-station open-end spinning machine during its operation. The large-magnitude suction forces rapidly evacuate from each box trash previously introduced therein by a beater roll disposed adjacent its inlet. The small-magnitude suction forces discourage escape of the trash from the boxes, pending evacuation thereof. Preferably the small-magnitude suction forces are applied simultaneously and substantially continuously to the outlets of all of the trash boxes, and the large-magnitude suction forces are applied successively to discrete groups of the boxes.
