摘要： PROBLEM TO BE SOLVED: To provide a needle threader for a sewing machine, allowing the whole head part to be compact and enabling an operator to securely execute needle-threading by one hand. SOLUTION: The needle threader is provided with a needle threading shaft in close proximity to a needle bar supporting a needle to shift it up and down, a needle threading hook of which the hook part can be introduced/removed into/from a needle hole, a regulation mechanism for regulating the descent limit of the shaft, a rotation mechanism for rotating the shaft in proximity to the limit of the shaft by a specified angle so as to insert the hook part through the needle hole, and a thread guiding member for guiding a needle thread to the hook part in proximity to the limit of the shaft. The guiding member is integrally formed with an operational body able to shift the shaft up and down and to rotate it around the shaft. The needle threader has an energizing member energized against the guiding member, pressing down the shaft by the operational body in proximity to the lower limit, after rotating the operational body in a direction where the guiding member closely approaches the needle, lifting the guiding member up by energizing power of the energizing member.

摘要： Provided is a micro-adjustment return mechanism for an overlock machine whereby, with a simple structure, can reliably return a thread tension micro-adjustment means for minutely adjusting the thread squeezing pressure of a tension plate to the origin position thereof. The present invention includes: a thread tension setting means (3) for collectively setting the thread squeezing pressure of a plurality of tension plates to a desired pressure; and thread tension micro-adjustment means (30a) that can be rotatably moved from the origin position to any other position to minutely adjust each set thread squeezing pressure. The present invention is also provided with: rotating bodies (30) that respectively rotate in association with the thread tension micro-adjustment means (30a), and include a projection (30b) on one surface thereof; and pairs of opposing slider crank mechanisms that surround each projection (30b). The fulcrums of the cranks of a pair of slider-crank mechanisms and the rotation center of a corresponding rotating body (30) are arranged so as to coincide. By setting and operating the thread tension setting means (3), the common slider is returned in the direction heading from the rotation center of the corresponding rotating body (30) toward the origin position thereof, such that the projection (30b) is held between the cranks.

摘要： Disclosed is a thread slack adjustment device for use in sewing machines which is capable of adjusting the amount of thread slack in overcast stitches without compromising the degree of freedom of the design in terms of placement, size, etc., of the needle plate. The disclosed device is provided with: a lower blade (12) which, disposed more towards the front than a needle entry position, is capable, paired with an upper blade, of cutting the edge of the processing fabric fed to the needle entry position and of moving left and right perpendicularly to the fabric feeding direction; a thread slip member (51) which, supported by a needle plate (100) so as to allow rocking left and right, sets the amount of slack of an overcast thread by the thread being hung across to a tip part when sewing near the needle entry position; and a rocking mechanism which rocks the thread slip member (51) left and right by moving in conjunction with the left and right movement of the lower blade (12).
