PURPOSE: A loop producing device of an embroidering machine is capable of producing embroidery having solid patterns, forming sometimes tufts with a lead arm set a cutter, exchanging and removing the lead arms having different clearances to form various loops and the tufts, preventing breakdown of a rod needle because the same is manufactured out of plastics, installing the same on a side and a rear of the embroidering machine sometimes and selecting over one of the loop producing device. CONSTITUTION: A loop producing device of an embroidering machine comprises: a front-to-back driving part(100) comprised of a gear(111) connected with a front-to-back driving motor(110), a worm gear(118) which is interlocked with the gear(111), converting rotary force into front-to-back driving force, a stopper bar(116) and stoppers(114,115) stopping rotation of the motor(110); a left and right driving part(200) containing a gear(211) connected with a left and right rotation motor(210) and driving right and left a lead arm part interlocked with the gear(211) and connected with a worm gear on the same axis; a lead arm part which is connected with a rotation axis of the left and right driving part(200), containing a lead arm(216) producing loops, a lead arm main body driving the lead arm(216), rubber stoppers(213,214) and a stopper bar(215) stopping rotation of the motor.
