Abstract
A fluctuation in tension of a knitting yarn to be fed is reduced, and the knitting yarn having an accurate length is fed even if the amount of demand for the knitting yarn is suddenly changed. A knitting yarn is interposed between a main roller and a driven roller and is thus fed, and is supplied from a yarn feeding port to a fabric, with storage depending on an inclination of a buffer rod. A yarn feeding controller predicts the amount of demand for the knitting yarn based on a signal sent from a knitting controller and PID controls a servo motor such that a position of a tip portion of the buffer rod aims for a position of an origin according to the inclination angle of the buffer rod, which angle is detected by an inclination angle sensor.
