Abstract (en)

The magnitude of an entering tension of an elastic yarn to a sending-out mechanism (34) of a flat knitting machine and the magnitude of a knitting tension provided by a buffer arm (40) are compared with each other, and, based on a result of comparison, an appropriate correction amount is determined from a correction parameter (50) to control the sending-out mechanism (34). The correction parameter (50) includes a correction amount for increasing an amount of elastic yarn when the entering tension is larger than the knitting tension, and a correction amount for decreasing the amount of elastic yarn when the entering tension is smaller than the knitting tension. Correction amount determining means (48) determines an appropriate correction amount from the correction parameter (50). Controlling means (36) controls the sending-out mechanism (34) by using the correction amount determined by the correction amount determining means (48).
