シンの上糸切断装置。[Scope of Claim for Utility Model Registration] A needle thread cutting device for a sewing machine that cuts the needle thread from the sewing needle to the workpiece after the sewing operation is completed, which connects a pair of needle thread clamping members that are provided so as to be openable and closable. opening/closing means for opening and closing; a first moving means for moving the upper thread holding member from a predetermined thread holding position in the ascending and descending path of the sewing needle to an initial position diagonally above the needle thread holding member; a cutting member made of a high electrical resistance material that generates a needle heat of 100 mL;
When the sewing operation is finished and the needle is raised, the first moving means moves the needle thread holding member from the initial position to the thread holding position, and the opening/closing mechanism operates to remove the needle thread. The upper thread is held by closing the clamping member, and the upper thread held by the upper thread clamping member is cut by the needle heat of the cutting member moved to the cutting position by the moving mechanism, and after cutting, the next sewing operation is started. A needle thread cutting device for a sewing machine, characterized in that a cutting end of the needle thread is held at an initial position by a needle thread holding member until the needle thread is started.
