Abstract
Device for cleaning an open-ended spinning turbine comprises a bell which can be fitted to a container holding the spinning rotor and which is mounted on an arm operated by a jack. The bell bears a piston of which the front tapered end probes the bottom of the throat for uniting the fibers in the rotor when the bell is joined to the container. The procedure consists in letting a certain quantity of fibers enter after breakage of the yarn so as to form a ring of fibers in the rotor and then to press this ring by means of the piston until the rotor stops, while the scraping or rubbing of the ring of fibers enables the impurities stuck in the area of the throat for uniting the fibers to be detached.
