An apparatus for molding an ornamental bead string is provided to weave an intermediate string threaded beads to a twisted string formed continuously by an upper string and a bottom string. A sewing machine is equipped to the upper portion of a body and has a top thread supply device(10) and a bottom thread supply device. The bottom thread supply device is elevated and rotated by the driving force from a driving motor mounted to the inner side of the body. A speed reduction device connected with the driving motor is formed at the upper side of the body. A rotation plate is formed at a side of the speed reduction device. An end of a transfer rod is eccentrically connected with the rotation plate. A middle thread supply device(30) is connected to the other end of the transfer road. A moving shaft(32) is slidably inserted into a side of a support(31) fixed to an upper side of the body. A guide block(33) is fixed to an end of the moving shaft, connected with the transfer rod and inserted into a guide rod(34) protruded to a side of the support. A rotation pulley(37) is combined with the other end of the support and connected with a stepping motor(35) and a belt(36) mounted to the body. An insertion portion(39) is inserted and supported to a plane shape insertion groove(38) formed to the inside of the rotation pulley.
