Abstract
An automatic textile machine includes a multiplicity of work stations each having its own work station electronics for controlling progress of work done at the work station. A method for detecting a position of a cop carrier carrying a textile cop in the vicinity of a work station includes evaluating mistuning of an oscillator circuit as information with a secondary coil disposed on the cop carrier; detecting the information transmitted by the cop carrier with a sensor device; carrying the information to the work station electronics; and processing the information with the work station electronics to initiate further operations. An apparatus for detecting the position of a cop carrier carrying a textile cop in the vicinity of one of the work stations includes a secondary coil disposed on the cop carrier, and a sensor disposed in the vicinity the winding station. The sensor is connected to the winding station electronics and detects information transmitted by the cop carrier. The sensor has an oscillator circuit to be mistuned by the secondary coil.
