PROBLEM TO BE SOLVED: To provide a method for joint treatment and a system therefor, wherein a joint is formed by joining the terminal end of the weft of a weft cheese in use and the initial end of the weft of a weft cheese to be used next, and to provide a yarn cutting system in the jet loom for improving the certainty of eliminating a joint. SOLUTION: These systems work as follows: a joint sensor 13 detects a joint Y3 made by joining the terminal end of a weft Y1 and the initial end of a weft Y2. Detection information thus obtained is transmitted to a control computer C. When the shift of the joint Y3 is detected, the control computer C halts a weaving activity. Thereafter, a weft is held on a weft holder 27, and in such a condition that a hook pin 151 is hooked on a yarn wrapping surface 142, the control computer C makes a slow reverse at a specified magnitude of a loom driving motor M, resulting in the reverse rotation of a yarn-wrapped bobbin 141, which, in turn, results in that the weft lying upstream from the bobbin 141 is wrapped together with the joint Y3 on the yarn wrapping surface 142 and reserved.
