A method for optimizing the operation of a spinning machine with regard to quality and productivity is provided. An apparatus, comprising a control device and the spinning machine is provided. A yarn having specified yarn properties is produced, a quality parameter of the yarn is sensed during the spinning operation, a parameter for setting the production speed is specified, the quality parameter and the parameter for setting the production speed are evaluated, and the production speed is set in dependence on a target variable, the target variable comprising the quality parameter.

Optimization of the operation of a spinning machine

In order to optically sense a yarn moved in the longitudinal direction of the yarn, a yarn sensor has a light source, a detector and a light guiding element. The yarn sensor is based on the effect of frustrated total internal reflection (FTIR). Because of the FTIR effect, scattered light exiting the light guiding element in the contact region between the yarn and an outer surface of the light guiding element is detected by means of the detector, in which case sensing of the yarn lying against the outer surface is enabled. Alternatively, the reduced intensity in the totally internally reflected beam is then sensed by the detector. The intensity in the totally internally reflected beam is reduced mainly by the scattered light coupled out of the light guiding element.
