摘要： A method and apparatus for removing fiber waste from yarn spinning rotors of open-end spinning machines and for removing trash waste liberated from fibers in their paths of travel to the respective rotors, utilizing a common primary airflow for drawing air from the rotors and for also drawing air adjacent the paths of travel of the fibers to the rotors so that the airflow adjacent such paths of travel will not interfere with movement of the fibers along such paths to the adjacent yarn spinning rotors. Preferably, the airflow from the rotors of each machine passes through a respective movable filter arranged to arrest fiber waste thereon periodically for intervals of predetermined duration permitting extinguishing of any fire which may have been ignited in the fiber waste being drawn from the rotors of the machines.

摘要： A method and apparatus of spinning yarns on an open-end spinning machine having a plurality of spinning positions, in which trash waste separated from the fibers of the slivers during advancement through respective fiber opening zones to respective yarn spinning rotors is continuously removed from the opening zones by a low velocity suction current of air and pneumatically conveyed along respective passageways to a central waste collection zone. In order to prevent accumulation of trash in the passageways and possible blockage thereby, the passageways are periodically purged by momentarily increasing the flow of air therealong to create a predetermined relatively high velocity in the passageways. A common source of suction may be employed for removal of the trash waste from the opening zones and also for removal of fiber waste from the respective yarn spinning rotors of the machines.
