Abstract
PURPOSE: To improve work efficiency and the quality of a product by carrying and rotating first and second pinch plates for holding a ring between them. CONSTITUTION: The piston rod 27a of a second air cylinder 27 pressurizes the rod receiver 28b of a rock arm 28 to an upper part and the rock arm 28 is rocked with a corner part 28a as a center. By the rocking, the upper tip part of the rock arm 28 pressurizes an arm part 72a which is integrally formed in the second pinch plate 72 against the energizing force of a torsion spring 118 energizing the second pinch plate 72 to the adhering side of a needle plate 2 and also against the energizing force of a compression spring 24 energizing the first pinch plate 71 to the side of the second pinch plate 72. Therefore, the first and the second pinch plates 71 and 72 are carried and rotated to the side for permitting the ring Ch to come close to a cutter 30 and rotated while pinching the ring Ch. When the ring Ch is crossed with the cutter 30 and inserted between a fixed blade 30a and a mobile blade 30b with the rotation, the mobile blade 30b is driven by synchronization with the driving of a sewing machine so that the ring Ch to be sewed in the seam of a cloth is separated from a pinch part by the first and the second pinch plates 71 and 72.
