Estimating the term…
A method for operating an open-end rotor spinning machine having a plurality of workstations, usually a large number, each including a spinning device with a rotor housing, to which negative pressure can be applied, in which a spinning rotor (23) revolves at a high rotational speed, to produce a yarn, as well as a winding device to produce a cross-wound bobbin (18), wherein the connection of the workstations to a central negative pressure supply can be selectively switched off. The application of negative pressure to the rotor housing is limited to the spinning devices which are producing yarn as well as the spinning devices which are repiecing.
Method for operating an open-end rotor spinning machine (1) having a plurality of workstations (4), which in each case have a spinning device (5) with a rotor housing (21), to which negative pressure can be applied, in which a spinning rotor (23) revolves at a high rotational speed, to produce a yarn (16), as well as a winding device (7) to produce a cross-wound bobbin (18), wherein the connection of the workstations (4) to a central negative pressure supply can be selectively switched off, characterized in that the application of negative pressure to the rotor housing is limited to the spinning devices which are producing yam as well as the spinning devices which are repiecing.
