(54) WEFT MEASUREMENT DEVICE FOR LOOM


(57) A weft measurement device for a loom is configured to measure a parameter of a weft yarn (Y) drawn from a yarn feeding unit (2) and weft-inserted by a weft inserting nozzle (8). The weft measurement device includes a weft sensor (30) including a weft measuring portion (34) and a weft guide unit (31) that guides the weft yarn (Y) to the weft measuring portion (34). The weft guide unit (31) includes a moving means (38) that moves the weft yarn (Y) to a non-measurement position that is separated from a measurement position in the weft measuring portion (34). The non-measurement position is set at a position separated sideways from a vertical plane (A) including the measurement position in the weft measuring portion (34).
