Title:
空気噴射式織機の緯入れ装置
Document Type and Number:
Japanese Patent JP5321662
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a weft insertion device for an air jet loom, which enables high-speed weft insertion.SOLUTION: A first tandem nozzle 3A is fixedly arranged on the upstream side of a weft insertion nozzle 2A provided on a slay 6, and a second tandem nozzle 4A is fixedly arranged on the upstream side of the first tandem nozzle 3A at an interval. A weft braking device 7A is arranged between the first tandem nozzle 3A and the second tandem nozzle 4A. The first tandem nozzle 3A, the weft braking device 7A, and the second tandem nozzle 4A are integrally configured. An acceleration tube 23 of the first tandem nozzle 3A is formed to have a length longer than that of an acceleration tube 41 of the weft insertion nozzle 2A. An acceleration tube 27 of the second tandem nozzle 4A is formed to have a length shorter than that of the acceleration tube 41 of the weft insertion nozzle 2A. Thus, the weft driving force of the second tandem nozzle 4A is set to be smaller than that of the first tandem nozzle 3A, thereby enabling high-speed weft insertion in a fluid jet loom while suppressing increase in fluid consumption and increase in the installation area of a weft insertion device.
