Abstract

A suction-air system of a textile machine, especially a rotor spinning machine, has at least one suction-air conduit, at least one spark sensor for detecting flying sparks within a measuring extent of the suction-air, the sensor including a measuring device with a sensing range at least partially overlapping the measuring extent, at least one electromagnetic wave receiver for generating an output signal when a spark enters the sensing range, and a driver and evaluation circuit for the measuring device. At least one source for generating electromagnetic waves is associated with the receiver and actuates a purposeful initiation of the spark sensor.
