Abstract
A weft processing apparatus for a jet loom comprises a first weft length measuring device installed at the far or downstream side of the warp shed through which the weft is inserted for measuring the length of a broken weft yarn piece. A weft withdrawal device for withdrawing a defective weft that has undergone abnormal insertion is provided at the entrance side of the warp shed. The length of the defective weft withdrawn by the withdrawal device is measured by a second weft length measuring device. A second weft withdrawal device may be provided at the far side of the warp shed for making it possible to measure the length of a broken weft yarn piece that might remain within the warp shed.
