ABSTRACT:
A stationary thread-cutting device for a sewing machine includes a guiding member and a cutter. The guiding member is mounted on a needle plate, and has a major wall defining a thread guiding route. The guiding route includes a lead-in area having an entry slot to permit entry of a leading end of a bobbin thread, a turn-around area for guiding the leading end, a corner piece disposed at the turn-around area, and a cutting station disposed adjacent to a lateral edge of the needle plate to define a lead-out path with the corner piece. The cutter is disposed under the major wall and adjacent to the cutting station, and has a cutting blade. After the bobbin thread is advanced beyond the cutting station, the bobbin thread is cut, thereby ensuring that a predetermined length of the bobbin thread is available for initial interlacing with a needle thread in a sewing operation.
