ABSTRACT:
A sewing machine is provided with a needle thread cutting device for severing the free end of the needle thread extending through the eye of the needle at the beginning of a sewing operation to prevent entanglement of the free end with the stitches being formed. A cutter element is mounted for oscillating movement in conjunction with the raising and lowering of the presser foot. The lower end of the cutter element is provided with a transverse leg extending across the upper surface of the presser foot in close proximity thereto rearwardly of the needle. The transverse leg portion is provided with a cutting edge on the side thereof remote from the needle. Subsequent to a previous sewing operation the raising and lowering of the presser foot will oscillate the cutter element to move the leg portion from a position behind the needle thread to a position in front of the needle thread so that upon initiation of a new stitching operation the free end of the needle thread will be severed relatively close to the first stitch.
