Abstract

A weft inserting apparatus (60, 70) for a fluid jet loom includes a plurality of weft supply lines (L), each having a yarn package (1), a weft measuring-and-retaining device (30), a weft-insertion nozzle (9), and a yarn sensor (3). The apparatus performs a weft insertion process by using the weft supply lines in a sequential alternating cycle. When a yarn abnormality is detected in a weft supply line, the apparatus excludes that weft supply line from the sequential alternating cycle and allows the weft insertion process to continue using only the remaining operable weft supply lines. Manually operated restoring means (35, 40) is connected to a weft-insertion controlling device (65, 75). The weft-insertion controlling device restores the excluded weft supply line on the basis of an output signal from the restoring means so that the excluded weft supply line is re-included in the sequential alternating cycle of the weft insertion process.
