Abstract
Disclosed is a thread feeding apparatus for an automatic embroidering machine. The apparatus is comprised of a head stem having a needle-working unit; a thread supplying unit supplying a colored thread selected among a plurality of threads; a guide pipe assembly provided at said head stem, having a first guide pipe receiving the thread from said thread supplying unit, and a second guide pipe having an upper end spaced axially from said first guide pipe and a lower end adjacent to said needle-working unit; and a thread taking-up unit having a take-up lever moving up and down across a thread transferring path, and a take-up bar coupled with the take-up lever in a transverse direction relative to movement of the take-up bar, moving reciprocally through a space between said first and second guide pipes according to the movement of said take-up lever, to allow said thread to be strained or loosened. With this configuration, in a single structure of the head stem, a supplying path of the thread is prevented from being curved, to thereby efficiently feed the thread.
