摘要： PROBLEM TO BE SOLVED: To suppress the dropping of a needle thread from a sewing needle at the time of the starting of sewing.
SOLUTION: This sewing machine 10 is equipped with a rotary needle thread take up member 20 which is arranged on the upstream side of the sewing needle 101 on a thread needle pathway, and at the same time, imparts a tension which periodically changes by the same cycle as the vertical movement of the sewing needle 101 to the needle thread. The rotary needle thread take up member 20 is equipped with a base section 21 which becomes the pivot side, and an arm section 22 which makes the needle thread T reciprocate in the longitudinal direction by rotating as it remains spanned with the needle thread T. A recess section 23 in which the needle thread T drops from the needle take up upper dead point position 26 of the needle thread T is provided on the arm section 22. The rotary needle thread take up member 20 is constituted by having a needle thread position changing means 30 which moves the needle thread T to the recess section 23 before a first stitch is formed.

摘要： PROBLEM TO BE SOLVED: To provide a sewing machine and a component thereof which reduce the amount of supply of lubricating oil to the utmost and also improves the abrasion resistance of a sliding portion, thus preventing a seizure of a sliding component.
SOLUTION: The component, e.g. a needle rod, which has a portion sliding on another component is prepared by welding a high-hardness constituent having a tungsten carbide to the sliding portion by using a phenomenon of electric discharge in a working solution. Thereby the abrasion resistance in the sliding portion of the needle rod is improved and the abrasion and the seizure of the sliding portion are prevented effectively, while, in addition, the amount of supply of the lubricating oil is reduced to the utmost.

摘要： PROBLEM TO BE SOLVED: To improve the attaching structure of a looper to a looper shaft, and realize the miniaturization of a cylindrical bed which integrally encloses them. SOLUTION: A looper base 5 is equipped with a supporting shaft 50 which projects at an approximately right angle on one side end, and integrally forms a looper 1 in the opposite direction from the supporting shaft 50 on the other side end. By using such a looper base 5, the supporting shaft 50 is inserted in a supporting hole formed at the shaft core part at the distal end of the looper shaft 2 which projects in the cylindrical bed B 1 . Then, the supporting shaft 5 is locked and fixed with fixing screws 51 and 51, and the looper 1 is attached to the looper shaft in such a manner that the looper 1 which is integrally formed on the looper base 5 may be projected approximately in parallel with the looper shaft 2 at a location being eccentric from the looper shaft 2.

摘要： PROBLEM TO BE SOLVED: To prevent the wear and burning of a sliding component and to cope with the acceleration of an operation speed by forming a coating layer with diamond-like carbon put on a sliding surface through an intermediate layer. SOLUTION: A sewing machine component 1 is a bar-shaped member composed of a metal such as chrome molybdenum steel and a heat treatment layer 10 is formed so as to increase the hardness on the surface. Also, on the surface of the heat treatment layer 10, the coating layer 12 made of the diamond-like carbon is attached through the intermediate layer 11. The intermediate layer 11 improves the attaching strength of the coating layer 12 to the heat treatment layer 10. Thus, the generation of burning in a sliding part is evaded, the durability of the sewing machine component is improved and the stable high-speed operation is made possible over the long period of time.
