Abstract
An opening machine for separating the fibres from intermingled impurities in cotton tufts comprises a storage bin into which cotton tufts to be processed are introduced, and an opening cylinder associated with cleaning blades for separating the impurities from the fibres and with suction openings for removing the impurities and the fibres separately. The opening machine comprises a pre-opening roller for performing a preliminary opening of the tufts. The cotton material is withdrawn from the bin by feed rollers, is processed by the pre-opening roller, and is introduced into a chamber in the form of pre-opened tufts. A final feed roller withdraws the tufts from the chamber and supplies them to the opening cylinder. The final feed roller works at a withdrawal rate greater than that of the feed rollers to prevent accumulation of the tufts in the chamber.
