The invention relates to a method for carrying out a test cycle at workstations (2) of a spinning or winding machine (1) by means of a test unit (17). According to the method, the test unit (17) is connected to a maintenance device (15) which can be moved along the workstations (2) on a rail (16) during the test cycle. The test unit (17) is physically connected to the maintenance device (15) in order to carry out the test cycle at the workstations (2) and is separated from the maintenance device (15) after the test cycle has ended. A corresponding test unit (17) can be physically connected to the maintenance device (15) in order to carry out the test cycle at the workstations (2) and can be separated from the maintenance device (15) after the test cycle has ended. A system comprising a plurality of workstations (2) arranged next to one another and a plurality of movable maintenance devices (15) additionally has such a test unit (17) which can be physically connected to one of the maintenance devices (15) in a freely selectable manner.

The invention relates to a method for operating a revolving flat card (1) and to a revolving flat card (1). The revolving flat card (1) has a controller (2) comprising an input module (3), a feed (6) and a cylinder (8) fitted with a cylinder clothing (9). A carding gap width (12) is formed between an outer surface (10) of the cylinder clothing (9) and a flat clothing (15). The revolving flat card (1) also has a carding gap width measurement arrangement (33) and an actuator (31) for adjusting the carding gap width (21) and a drive (42) for controlling a rotation speed of the cylinder (8). The input module (3) measures a process temperature, detects a target process temperature together with an associated maximum process temperature and detects a control range and a maximum value for the carding gap width (21), The controller (2) controls the target process temperature by adjusting the carding gap width (21) and/or the feed (6) and/or a rotation speed of the cylinder (8).
The invention relates to a method for operating an air-jet spinning machine with multiple spinning positions, wherein the spinning positions each comprise a spinning nozzle (1), which is supplied with a fibre composite (3) during a spinning operation using a delivery device (2) of the respective spinning position, wherein the fibre composite (3) is made to rotate within the spinning nozzle (1) using a swirling air flow, such that a yarn (4) is formed from the fibre compsite (3), and wherein the yarn (4) is withdrawn from the spinning nozzle (1) in a predefined spinning direction using a withdrawal device (5) of the respective spinning position. According to the invention, the ratio between the delivery speed of the delivery device (2), with which the fibre composite (3) is supplied to the spinning nozzle (1), and the withdrawal speed of the withdrawal device (5), with which the yarn (4) is withdrawn from the spinning nozzle (1), determining the spinning tension, is altered at least at one of the spinning positions during the spinning operation. The invention also relates to an air-jet spinning machine with multiple spinning positions.
An open-end spinning device (5) has an opening roller (10) arranged rotatably in an opening-roller housing (11), a spinning rotor (12) which is arranged rotatably in a rotor housing (13), which can be exposed to negative pressure and is closable with a cover element (14), a fibre-guiding channel (16) which extends in a fibre transport direction from the opening-roller housing (11) as far as the rotor housing (13) and pneumatically connects the opening-roller housing (11) to the rotor housing (13), wherein the fibre-guiding channel (16) has an entry section (17), which is arranged in the opening-roller housing (11), with a fibre inlet region (19) and an exit section (18), which is arranged in the cover element (14) of the rotor housing (13), with a fibre outlet mouth (20), and also a bypass channel (22) which branches off from the fibre-guiding channel (16) at at least one branch point (21) and can be exposed to negative pressure. The branch point (21) of the bypass channel (22) is arranged in the entry section (17) of the fibre-guiding channel (16) downstream of the fibre inlet region (19) in the fibre transport direction.
