Claims

[Scope of utility model registration request]

With respect to the thread winding surface of the weft length measuring member, a first weft locking body disposed near the winding surface and a second weft locking body disposed on the weft insertion side with respect to the first weft locking body. In the weft length measuring device for a fluid injection type loom, the weft thread length measuring device for a fluid jet loom is configured to wind and pull out the weft thread supplied from the weft supply section onto the thread winding surface by moving the weft thread up and down in synchronization with the weft insertion timing. A weft gripping member is provided that is moved by a drive mechanism between a gripping position where the second weft locking body engages with the top and grips the weft when the second weft locking body moves upward, and a balloon retracted position, and the weft gripping member is configured to Weft yarn measurement in a fluid injection type loom, characterized in that the second weft locking body is moved to the retracted position when the second weft yarn locking body moves downward, and is configured so as not to become an obstacle to the weft yarn flying from the winding surface. Long device.
