发明名称 Sewing machine with improved thread cutting mechanism
摘要 A sewing machine includes a needle plate having a needle hole through which a sewing needle is allowed to pass, a thread catcher reciprocally moved forward and backward below the needle plate and being elongated in a moving direction, the thread catcher having a frontward end with respect to a direction of forward movement of the thread catcher and including first and second generally hook-shaped catching portions, and a cutting blade located between the first and second catching portions at least during backward movement of the thread catcher to cut a thread caught between the first and second catching portions. The first catching portion is located nearer to the frontward end of the thread catcher than the second catching portion with respect to the moving direction of the thread catcher during forward movement of the thread catcher. The first catching portion is further spaced from and located nearer to the needle hole of the needle plate than the second catching portion with respect to a direction perpendicular to the moving direction of the thread catcher. The thread catcher is moved backward so that the thread caught between the first and second catching portions intersects the cutting blade.
