(54) Electric selvage device control method for fluid-jet loom


(57) An electric selvage device control method times the selvage shed closing operation of an electric selvage device (3) to close a selvage shed (18) of selvage yarns (17) by the electric selvage device (3) at an optimum phase of a weaving cycle. A sensor (25, 26, 27, 44, 45) provides a detection signal upon the detection of the passage of a picked weft yarn (2) by a predetermined position. The electric selvage device (3) is driven on the basis of the detection signal for the selvage shed closing operation to grip the picked weft yarn (2) by the selvage yarns (17) without obstructing the travel of the picked weft yarn (2)at the earliest possible phase of the weaving cycle.
