摘要： Provided is a double-needle lockstitch sewing machine that can easily sew a fabric rolled into a tubular shape by two rows of lockstitch. The double-needle lockstitch sewing machine includes: a pair of needles (9) that reciprocates in an up-down direction; a pair of loop catchers (40) that is arranged respectively corresponding to the pair of needles (9) and that catch loops of needle threads formed by the needles (9) by rotating about hook shafts (41) extending in the up-down direction; a lower shaft (20) that is disposed in front of the needles (9) and the loop catchers (40) in the cloth feeding direction and extends in the left-right direction and that rotates in conjunction with a main shaft (10) that drives the needles (9); and connecting shafts (30) that extend in the cloth feeding direction and are connected to the lower shaft (20) and the hook shafts (41) in a power transmittable manner to rotate. The loop catchers (40) are rotationally driven in conjunction with an up and down movement of the needles (9) as a rotational power of the lower shaft (20) is transmitted to the hook shafts (41) via the connecting shafts (30). Thus, it is possible to easily sew a tubular article with two rows of lockstitch seams.

摘要： Embroidery and sewing machines can utilize rotary hooks to attach thread to materials. An adhesive joint configured to sever if the rotary hook becomes jammed prevents damage to the rest of the drive system. The severable joint is located between a sleeve and a drive shaft nearest the rotary hook to allow for easy removal and repair of the joint.

摘要： The present invention provides a bobbin thread feeder of sewing machine of simple structure in which a lower thread can be reliably fed at an appropriate tension. A lower thread bobbin 21 can be removably contained through an opening for containing a lower thread bobbin 17 in a rotary hook 20 of a horizontal rotary hook 30 provided in a sewing machine frame. A thread tension plate and a thread tension spring are attached while overlapping along the inner circumference of the rotary hook 20, and function as a tension generating portion 22 for imparting resistance to pulling out a lower thread being guided through the gap between the thread tension plate and the thread tension spring. A needle plate 16 with an opening for taking the lower thread bobbin 21 in and out is provided above the rotary hook 20. The needle plate 16 comprises a guiding slit 27 that guides the lower thread formed thereon. The guiding slit 27 is formed substantially linearly in the extending direction of the overlapping portion of the thread tension plate and the thread tension spring.

摘要： The hook (15) of a sewing machine (1) is mounted so that it can move on a hook carrier. Through a sliding movement of the hook carrier, the hook (15) is brought from its operating position into a bobbin case removal position. Through the sliding movement, the hook (15) with the bobbin case (17) is placed at or above the opening, which is created by the flap (13) in the lower arm (5). In this way, the removal of the bobbin case (17) or the bobbin is made considerably easier.

摘要： A wire-guiding structure of a shuttle of a sewing machine is disclosed. One end surface of the shuttle is formed with a wire-receiving hole for supplying wire continuously. A wire for seaming is supplied to an interior of the shuttle from an external larger scale wire-winding and the wire is wound around the wire-winding wheel for outputting. It is unnecessary to update the shuttle so as to increase the finishing efficiency. Furthermore, the end surface of the shuttle is installed with a wire-guiding rod for guiding wire successfully so that the wire can run along a predetermined path efficiently. Thus wire can be supplied successfully. Moreover, a wire-winding wheel is installed in the shuttle so that wire will be easily wound around the wire-winding wheel smoothly. Thus wire is supplied to the sewing machine successfully.
