Spinning machine e.g. open-end spinning machine, has control device that is formed such that permanent downtime of resilient drawing-off rollers is controlled during standby phase while starting maintenance work

摘要

The machine has spinning stations (1, 1'), each station including a yarn drawing-off device (5) for drawing a yarn (F) from a spinning unit (4). The drawing-off device is attached to a control device (8) and includes a pair of resilient drawing-off rollers (16, 17) and a single powered drive (18) that is controlled by the control device to drive the rollers. The control device is formed such that a permanent downtime of the rollers is controlled during a standby phase while starting a maintenance work, and the rollers are temporarily driven according to a preset standby phase speed profile.
