In an air jet loom having a movable suction conduit operatively connected to a suction source, a particular fringe cutting mechanism and waste fringe removal mechanism are provided that minimize yarn waste and minimize loom downtime. The fringe cutting mechanism is mounted upstream of the loom temple with respect to the direction of fabric movement, and is actuated by the movement of the reed of the loom as the reed moves in a downstream path of movement. The movable suction conduit, in addition to capturing the picks from the main jet of the loom, comprises the waste removal mechanism for removing cut fringe so that no fringe binder yarns, or the like, are necessary. The fringe cutter includes an anvil block with a lifting stiff wire extending outwardly from it to lift fringe yarn to be cut onto the block surface so that it is engaged by a cutting blade rotated into contact with the block. The suction conduit includes a nozzle having an entrance diameter large enough to guide errant picks into the high suction throat of the nozzle, the throat diameter being such that tension on the leading ends of the filling yarn is maximized. The nozzle is placed immediately adjacent the confuser exit so that the pick fringe length can be minimized.
