VERTICAL ROTATING HOOK COMPLETE

Japanese Patent JP3420548

B2

PROBLEM TO BE SOLVED: To provide a rotating hook complete that can prevent the yarn division portion of the rail of a rotating hook bobbin case holder from hitting the downstream side end in the direction of rotation of rotating hook of the peripheral wall of the rotating hook.
SOLUTION: By forming a magnetic pole in the vicinity of the upstream side end of a route 58 in the direction of rotation A of the external pot and/or in the vicinity of the yarn division portion 77 of a rotating hook complete 51 having a rotating hook 52 in which the route 58 extending circumferentially in the inside periphery of a peripheral wall 80, and parted in a notch 73 is formed, and which is rotationally driven around an axis of rotation L3, and a rotating hook bobbin case holder 53 in which a rail 59 extending circumferentially in the outside periphery of a peripheral wall 60 from the yarn division portion 77 to the portion 75 is formed, and the rail 59 fits into the groove 58 in a locked state, a magnetic force generation portion 87 is formed, whereby the yarn division portion 77 is displaced toward the bottom wall 61 just before arranged in the notch 73, and the yarn division portion 77 does not hit the downstream side end of the peripheral wall 80 in the direction of ration A of the external pot, preventing a large shuttle sound due to collision from being generated.
