ABSTRACT:
An object of at least one embodiment of the present invention is to stably feed a yarn by suppressing the effect of inertia in a buffer mechanism provided in a yarn feeding path. In at least one embodiment, a yarn feeder of the weft knitting machine feeds a knitting yarn from either of ends of a needle bed through a yarn feeding member to a knitting needle which carries out knitting motion based on knitting data while reciprocating the yarn feeding member in a longitudinal direction of the needle bed. A buffer rod is provided in the feeding path for the knitting yarn. Before the yarn feeding member starts to feed the knitting yarn to the knitting needle. a yarn feed controller carries out control to feed out the yarn to the buffer rod beforehand in a moving direction in which the feeding path is extended and to pull back the yarn stored in the buffer rod in a moving direction in which the feeding path is reduced. Thus, since an overshoot and an undershoot by the effect of inertia is caused by the buffer rod provided in the feeding path for the knitting yarn can be suppressed, the knitting yarn can be stably fed.
