Document Type and Number:
Japanese Patent JP3496861
Kind Code:

Abstract:

PROBLEM TO BE SOLVED: To provide the subject apparatus of simple constitution, capable of efficiently storing weft with a small amount of a circular air flow and not damaging the weft.
SOLUTION: This weft storing apparatus has a cylindrical storage part 20 fixed to a revolving shaft 10 rotating synchronously with the main shaft of a water machine and a holding part 16 fixed to the revolving shaft 10 coaxially with the storage part 20. The holding part 16 has a truncated cone-shaped side converging from the edge part of the storage part 20 in a weft drawing direction and is equipped with a stationary cover 34 provided with a channel part 32 constituting a part of a circular air flow passage 30 which covers the truncated cone-shape side and rotates a weft. A channel part 26 constituting the circular air flow passage 30 is formed on the truncated cone-shaped side of the holding part 16 opposing to the channel part 32 of the stationary cover 34. The ratio of the central diameter of the circular air flow passage 30 to the outer diameter of the storage part 20 is 0.4-0.85.
