Abstract
A yarn selector unit of a loom has a number of feeders associated one each with a weft yarn. Each feeder is drivable by a tongue drivable selectively via a lever by way of a slide. The tongue and therefore the feeder are moved into a different position when it is required to present a weft yarn to a gripper or withdraw a weft yarn. The tongue is moved transversely by two actuators disposed opposite one another into a predetermined top or bottom position relative to the actuators by the action therefor. Positioning of the tongue relative to a tongue-moving slide is therefore always clearly defined so that misactuation of the yarn selector unit cannot occur.
