。 It consists of a thread winding stand with a slit formed therein, a thread control cam that is fixed to a rotating shaft and whose protrusion amount from the slit changes as the shaft rotates, and thread guides arranged on both sides of the thread control cam. In a thread control device of a sewing machine disposed on a thread supply path from a supply source to a looper, a presser plate is arranged on one side and a cutter is arranged on the other side across the thread supply path from the thread supply source to a thread control cam, The amount of protrusion of the thread control cam from the slit increases, and when the thread is reeled in by the thread control cam, the presser plate and the cutter are separated, the amount of protrusion from the slit decreases, and the thread control cam The present invention is characterized in that at least one of the presser plate and the cutter is reciprocated in synchronization with the yarn control cam so that the yarn is pinched between the presser plate and the cutter when the yarn fed into the looper is let out. A device to prevent thread from getting stuck in the looper thread control device of a sewing machine.
