ABSTRACT:
A yarn feeder intended particularly for flatbed knitting machines and elastic yarns has a yarn tension sensor which is provided with a calibration device. This device lifts the yarn from a peg that is part of the yarn tension sensor, at times in which this can be done without impairing operation of the yarn feeder. Such times are preferably time slots when no yarn feeding is necessary. Once the yarn has been lifted from the peg, a zero point calibration is performed. Zero point drifting of the entire sensor system, including its measurement circuit, can be detected and compensated for.
