| 摘要 |
The invention relates to a device for inserting two weft threads into two adjacent warp sheds in a loom with central jet insertion. Pairs of opposite outlet ducts (11) and (12), (111) and (112) of nozzles (1), (101) respectively, communicate with inlet ducts (3), (103) respectively. Air points (6), (106) respectively are provided to change the directions of advance of weft threads (2), (102) and input air streams (4), (104) respectively and tipping nozzles (7), (8) and (107), (108) respectively can be alternately opened and have discharge directions (9), (10) which are mutually crosswise directed into said pairs of opposite outlet ducts (11) and (12), (111) and (112) respectively. <IMAGE> |
