摘要： A tension shaft projects upwardly from a frame. A tension adjusting nut is adjustably screwed into an upper portion of the tension shaft. A pair of tension disks are rotatably supported by the tension shaft. A tension spring is supported by the tension shaft between one of the tension disks and the tension adjusting nut for urging one of the tension disks toward the other tension disk. A thread guide member fixed to the tension shaft has a plurality of thread holes. The device is characterized in that a bobbin thread threaded into the plurality of thread holes is elastically clamped between the pair of tension disks.

摘要： A thread cutting knife device in a sewing machine having a bed has a lower shaft rotatably supported at the bed and a throat plate mounted thereon. A hook is attached to the lower shaft and extends beyond a throat plate. A thread cutting knife and a loop spreading plate are adapted to cross between the hook and the throat plate to cut a needle thread looping portion at a cloth side and a bobbin thread. The knife and the plate are respectively rotatably supported by the lower shaft. The knife has a blade at an upper edge of the tip end thereof. The loop spreading plate has a thread dividing portion extending into the needle thread looping portion at the cloth side and a thread looping portion at the side of the needle. A thread drawing portion is formed at one edge of a base of the dividing portion for holding the needle thread looping portion at the cloth side and the bobbin thread. A blade positioned at the side of the throat plate and is opposed to and crosses the blade of the thread cutting knife.
