The present invention relates to a thread-feeding apparatus for a circular knitting machine. The thread-feeding apparatus includes: a driving motor installed on a frame; a driving pulley connected to the driving motor; a plurality of electric pulleys connected to the driving pulley and corresponding to a plurality of skeins; an electric belt connected to the driving pulley and to the electric pulleys to enable the electric pulleys to interlock with one another when the driving pulley is rotated; power transmission units fixed to the frame and connected to the electric pulleys to receive rotating power from the electric pulleys; and take-up rollers installed on the power transmission unit to receive rotating power from the electric pulleys transmitted from the power transmission unit and to guide a thread supplied from the skeins toward a needle. The driving motor includes an inverter for adjusting the rotating speed thereof, wherein the inverter is controlled by a controller for adjusting the rotating speed of the driving motor. Thus, a worker can adjust the rotating speed of the driving motor while confirming numeric data through a display unit of the controller. As a result, a beginner can easily adjust a thread feeding rate, and the wear of the thread resulting from continuously contacting flanges of the take-up rollers can be prevented when the thread supplied from the skeins to the needle passes through the take-up rollers. When the take-up rollers are stopped, the thread does not unravel downward because the thread is no longer pulled downward. |
