WEFT INSERTION METHOD AND WEFT INSERTION DEVICE FOR RAPIER LOOM

PROBLEM TO BE SOLVED: To reduce bending of the warp and sliding thereof on a reed etc. because of a positional relationship between a weft guide member guiding a weft to a chatchable position and the reed, and preventing the weft from being damaged. SOLUTION: In a weft insertion device 1 of a rapier loom, to insert a weft 2 through a guide hole 4 at a tip end part of a weft guide lever 3 and to guide the weft 2 connected to a woven fabric 6 to a catchable position of a rapier head 7, the weft guide lever can reciprocate between first and second positions P1 (retreat position) and P2 (guide position). The guide hole 4 is located at the second position P2 at start of weft insertion so that the rapier head 7 catches the weft 2 at the second position P2. Then, before beating up, the weft guide lever 3 is driven to move the guide hole 4 toward the first position P1, thereby reducing bending of the warp 2 and sliding of the warp 2 on a reed 12 etc. because of a positional relationship between the weft guide lever 3 and the reed 12 and preventing the weft from being damaged because of bending and sliding.
