摘要： In a sewing machine, an elevating unit is configured to be integrally raised and lowered with a threading lever of a threading apparatus. Furthermore, an operating lever is coupled to a lever interlocking mechanism that interlocks with the rotational operation of the operating lever. Upon pressing threading lever downward from an initial position when operating lever is at an operating position, an elevating unit engages with lever interlocking mechanism. Operating force applied to threading lever is transmitted to operating lever via lever interlocking mechanism, thereby turning operating lever from operating position to non-operating position. Accordingly, even when a presser is at a raised position, by pressing threading lever downward, operating lever is turnable from operating position to non-operating position, thereby allowing presser to return to pressing position.

摘要： Disclosed herein are a lower-thread supply device of sewing machine and a sewing method. The device includes a bobbin case (300) having an outlet (330) from which lower thread is drawn out, and a needle through-hole (340) through which a needle (600) moving downwards with upper thread (a) being fitted passes, and a hook body (200) in which the bobbin case (300) is mounted, the hook body being installed to be rotatable by a power device of a sewing machine, guiding upper thread (a2) on a sewn fabric side to a front area of the bobbin case (300) while catching and dragging the upper thread (a) via a hook (210), and guiding upper thread (a1) on a spool side to a rear area of the bobbin case (300). The bobbin case (300) is installed not to be rotated when the hook body (200) rotates.

摘要： A sewing machine includes a thread take-up lever that supplies an upper thread to a needle from a thread supply source, a hook which catches the upper thread inserted in the needle, and which intertwine the upper thread with a lower thread, and a control unit that controlling a hook release phase at which the hook releases the upper thread in such a way that a hook/upper-thread necessary amount that is necessary when the upper thread is intertwined with the lower thread becomes smaller than a thread-take-up-lever/upper-thread supply amount that is supplied by an operation of the thread take-up lever. The control unit controls the hook release phase at a plurality of timings.

摘要： A thread take-up lever guard in a multi-needle sewing machine provided with a support disposed on the front surface of a head, a plurality of needle bars each having a needle attached to the lower end, and a plurality of thread take-up levers disposed to oppose the needle bars respectively and protruded from the support to be able to oscillate vertically. The thread take-up lever guard prevents a needle thread carried on a selected thread take-up lever from being caught by an adjacent thread take-up lever assuming a standing posture or is tangled with another needle thread carried on the standing thread take-up lever. The thread take-up lever guard comprises a separator disposed on the support such that every adjacent two thread take-up levers may be isolated from each other over a predetermined range of routes along which the take-up levers reciprocate. The separators are notched at positions where thread holes of the thread take-up levers are situated when the thread take-up levers are assuming predetermined standing postures.

摘要： A thread take-up device comprising a loop tightening member adapted to reciprocate within a predetermined range limited by a thread slackening limit position where the loop tightening member is located when a thread loop is expanded to its maximum extent by a loop-seizing member, and a loop tightening limit position for tightening the thread loop; and a movable member adapted to reciprocate within a predetermined range limited by a stopping position defined within the range of reciprocation of the loop tightening member above the loop tightening limit position, and a position corresponding to the thread slackening limit position of the loop tightening member. The respective loci of the recess for engaging the needle thread of the loop tightening member, and the thread catch of the movable member overlap each other. The movable member is normally resiliently biased toward the stopping position by the substantially constant resilience of a resilient part thereof or by means of a separate resilient member, so that a predetermined length of the needle thread is secured during the threading operation irrespective of the stopping position of the loop tightening member, and the thread loop can be smoothly released from the loop-seizing member.

摘要： A thread handling device is disclosed in a type 301 lockstitch rotary hook loop taker sewing machine having a three-to-one hook to arm shaft ratio for controlling and metering slack needle thread prior to needle penetration to prevent the thread from wrapping around the point of the needle, which could prevent loop seizure, break the thread, or interfere with correct stitch formation. The thread is guided between two stationary members, with the controller between the members, the controller comprising an edge attached to the needle bar drive connecting link, moving with it, and only engaging the thread as the take-up and needle bar descend, providing a lengthened thread path prior to needle penetration.
