Abstract

A fluid jet loom (1) performs a weft insertion process in which a retaining pin (8) retracts to release a weft yarn (4) stored in a weft measuring-and-storing device (5), a weft brake device (40) applies a braking force to the weft yarn (4) at a brake start timing (t3, θ3) while the released weft yarn (4) is being inserted into a shed (17) by a jet from a main nozzle (10), and the retaining pin (8) projects to stop the weft yarn (4) and thereby finishes the weft insertion process. A remaining weft-insertion length (L1) to a final weft arrival position is input beforehand to the weft brake device (40) as an input value, and the weft brake device (40) determines the brake start timing (t3, θ3) on the basis of the remaining weft-insertion length (L1) and applies the braking force to the weft yarn (4) at the determined brake start timing (t3, θ3).
