The present invention relates to a cord yarn feeder for embroidery machines, and more particularly, to a tension control device of a cord yarn feeder for embroidery machines that can cope with a change in tension of various cord yarns.

In general, the embroidery machine is to form the desired embroidery pattern by moving the needle using the thread supplied to the surface of the fabric. When the embroidery pattern is to be remarkably three-dimensional, such as the rim, the three-dimensional effect is expressed through the double embroidery using only the yarn due to the characteristic of the needle that can not use a thick thread.

In order to solve the above problems, a cord yarn supplying apparatus capable of supplying cord yarn (or decorative yarn) such as a thick thread has been developed.

The cord yarn supplying device moves the cord yarn from side to side to supply needles to seal the cord yarn to the fabric to make a desired pattern.

This conventional cord yarn supply apparatus for a embroidery machine is shown in FIG.

The cord yarn supplying device 10 for the embroidery machine includes a motive power unit that mounts the motive gear to the rotating shaft of the step motor 16 to provide power to the outside by mounting the step motor 16 ( 17) and the upper and lower guide plates (18, 19) for connecting the cord yarn drawn out from the cord yarn bobbin connected to the embroidery machine to the fabric, and the cord yarn supplied from the upper and lower guide plates (18, 19). Cord yarn supply unit 13 for supplying the cord yarn while receiving the driving force of the motor 16 through the transmission means and rotating the left and right repeatedly, and a support for supporting the rotation of the cord yarn supply unit 13 in the guide portion It consists of 21.
