摘要： In this overedge sewing machine, when stitch width is adjusted, an adequate excess thread proportional to the adjusted stitch width is obtained. An overedge stitch can be steadily sewn without excessive stitch tension, even when the stitch width increases. By operating one adjustment member, the position of the lower knife holder and the stitch-support member can be easily adjusted, and the stitch width can thus be easily altered.

摘要： This invention provides an overlock sewing machine with a threading mechanism that is both easier and more efficient to use. As shown in FIGS. 1 and 7, the overlock sewing machine has a vertically movable needle (6, 106), a looper carriage (18, 118) connected to a rotating shaft, and a looper (11, 111) on the end of the looper carriage. The looper extends laterally over the looper carriage and has a thread-receiving eye (11a, 111a). The looper and the needle cooperate to form a chain stitch. As shown in FIGS. 3 and 9, a thread-guiding member (25, 125) next to the looper pivots with the looper to guide a thread LT through the thread-receiving eye. A movable lever (30, 130) pivots with or relative to the looper. A thread-delivering member (39, 139) mounted on the movable lever that can be set in two positions: a first position corresponding to a first position of the thread-receiving eye, and a second position corresponding to the thread-guiding member. In the second position, the thread passes through the thread-guiding member.

摘要： A threading apparatus for a sewing machine includes a moving mechanism for moving a threading member between a first position where the threading member is close to a needle eye and a second position where the threading member is away from the needle eye. The moving mechanism includes a moving actuating member, a transmitting actuating member, a transmitting string-shaped member, and a moving string-shaped member. The transmitting string-shaped member is moved in such a direction that the moving actuating member is moved from a non-operative position to an operative position when the operating member is operated so that the transmitting actuating member is moved. The moving actuating member is moved from the non-operative position to the operative position so that the moving string-shaped member is moved in such a direction as to draw the supporting member.
