Title:
WEFT-INSERTING NOZZLE OF FLUID JETTING TYPE LOOM
Document Type and Number:
Japanese Patent JP3934026
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To optimize a space dimension between a rectifying fin on upstream side and a rectifying fin on downstream fin and a relationship between the number of a water supply hole and the number of rectifying grooves while optimizing the number of the rectifying grooves of a plurality of rectifying members of a weft-inserting nozzle.
SOLUTION: The weft-inserting nozzle of the fluid jetting type loom comprises a needle 1, a nozzle body 2 in which a water supply hole 13 formed in a hollow shape and passing through a hollow part 3 is provided and the needle is inserted into the hollow part 3 and a circular chamber 4 made to communicate with the water supply hole is constituted between the top of the needle 1 and the nozzle body 2, and a plurality of rectifying fins 5 and 6 arranged in the circular chamber in turn in the advancing direction of weft. Each rectifying fin has a plurality of rectifying passages 17, 30 and 20 provided at equal spaces in the circumferential direction and each extending to the shaft direction. In the weft-inserting nozzle of the fluid jetting type loom, the number of each rectifying passage of a first rectifying member and a second rectifying member is kept to ≥6 and ≤40 and mutually has no common denominator.
