Abstract
Yarn loops are unwound from a stationary weft-winding drum during a weft insertion. A weft-braking device locks the yarn unwinding from the drum at the end of the insertion, and comprises at least one braking member which is arranged by side of the drum near its delivery end and is movable under control of an actuator between a resting position in which it is spaced from the outer surface of the drum and does not interfere with the unwinding yarn, and an operative position in which it engages the outer surface of the drum and cooperates with it to brake the yarn.
