OPEN-END SPINNING PROCESS AND DEVICE

摘要

In order to spin a thread (4) by means of an open-end rotor spinning device, the threads are supplied to a thread guiding surface (16) from which the threads are deposited on the sliding wall (7) of a spinning rotor (1) after crossing a gap (17). An air flow (30) is blown into the spinning rotor (1) through a gap (17), then evacuated from the inside of the spinning rotor (1) without going once again through the gap (17). A device (9, 20) is associated to the gap (17) in order to generate the air flow by generating a pressure drop that makes the air flow (30) through the gap (17) into the spinning rotor (1).
