Open-end spinning device with a spinning rotor and a pneumatic cleaning device associated therewith and method for cleaning a spinning rotor of an open-end spinning device

摘要

An open-end spinning device (1) has a spinning rotor (4) arranged in a rotor housing (2) with a rotor cup (5) and a rotor shaft (6), wherein the open-end spinning device (1) comprises a pneumatic, preferably spinning device-specific, cleaning device ( 7) for cleaning the spinning rotor (4) is associated with compressed air, which comprises at least one with a compressed air source (8) connected to the cleaning bore (9). Between the cleaning bore (9) and the compressed air source (8), an amplifier device (10) is arranged, by means of which the cleaning bore (9), the compressed air with a flow rate in the range of 50 l / min to 800 l / min can be fed. In a corresponding method for cleaning a spinning rotor (4) of an open-end spinning device (1) with a pneumatic, preferably spinning device-own, cleaning device (7) for cleaning the spinning rotor (4) with compressed air, wherein the cleaning device (7) at least one cleaning bore (9 ), the spinning rotor (4) during the cleaning, the compressed air is supplied at a flow rate in the range of 50 l / min to 800 l / min.
