The sensor of the traction of textile yarn, yarn feeder and the process for calibration of a sensor of the tensile strength of textile yarn.

摘要

"Sensor of traction of textile yarn, yarn feeder and method for calibration of a sensor of the traction of textile yarn.A device for yarn feeder, particularly for knitting machines of the bed plane and elastic yarns.It has a traction sensor wire which is provided with a device for calibration.This device lifts the wire from a pin, which takes part in the sensor of the traction wire.In a few moments in which this can be done without any injury to the operation of the device of yarn feeder.Such moments, preferably, are periods of time in which there is no need of wire feeding.Once the yarn has been elevated from the pin, a zero point calibration is carried out; the fluctuation of the zero point of the sensing system entirely, including the meter circuit 61.Can be detected and compensated.
