ABSTRACT:
A heat sensor which detects the heat generated from sliding frictional contact with a traveling yarn in a textile machine and generates control signals therefrom for the controlling of a yarn winding operation. A temperature-sensitive electric resistor, especially a thin-layer resistor or a film thermometer, serves as the heat sensor. The heat sensor is connected e.g. via a signal converter to control devices, e.g. to a controllable yarn brake and/or to a drive motor for yarn take-up. When the measured temperature rises above a limit value, the braking force of the yarn brake can be first lowered and then the speed of the drive motor can be reduced.
