Yarn feeding device for flat knitting machine

摘要

An object of the invention is to be provide a yarn feeding apparatus of a flat knitting machine capable of accurately predicting a required amount of a knitting yarn and knitting a fabric while supplying knitting yarn necessary for knitting. The knitting yarn is fed out based on an idea shown in a solid line in consideration of a yarn speed corresponding to the requirement for knitting yarn produced according to the movement of a yarn feeding member as shown by chain lines in FIG. 6 (b). A knitting yarn is stored on a buffer rod at a start of knitting because the speed of a motor such as a servo motor for feeding a knitting yarn lags behind the yarn speed. A knitting yarn that runs short at the time of deceleration at an end of knitting is also fed out in advance.
