Patent ID: 7363101

Claim:
A knitting machine that supplies yarn from a yarn processing device to a knitting needle of a needle bed in order of a buffering arm and a yarn feeder, compares remaining length to be knitted W, which is a total value obtained from knitting data and obtained by summing up consumed yarn length of each loop to be knitted from a changeover position on a knitting fabric for changing over a knitting yarn to an after-processed yarn to an actuating position of the yarn processing device, with yarn guide length L between the yarn processing device and a yarn feeding position at a position of actuating the yarn processing device to feed the knitting yarn to the knitting needle, and thereby controlling a timing for operating the yarn processing device, the knitting machine comprising: a sensor for obtaining buffer length of the arm from a direction of the arm; means for comparing the yarn guide length L in preset buffer length of the arm with the remaining length to be knitted W, to control deceleration of knitting speed so that the knitting speed becomes zero or a low speed at the needle bed at the point of time when a yarn feeding position C is reached when L≦W is satisfied; and timing means for obtaining the buffer length of the arm at the yarn feeding position C by means of the sensor, and operating the yarn processing device at the point of time when reeling out, from the yarn processing device side to the needle bed side, yarn of a length corresponding to a difference between the preset buffer length of the arm and the buffer length obtained by the sensor.
