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.

Fringe reduction mechanism

A structure for weaving without outer leno yarns on an air jet loom eliminates the auxiliary selvage from both sides of the fabric being woven. A mechanical filling yarn clamp is disposed between the filling detector and suction source on the right-hand side of the loom for holding the ends of the picks during weaving. A suction source nozzle is mounted adjacent and exterior of a fringe cutter downstream of the temples on the right-hand side for removing pick trimmings cut by the fringe cutter. A combined clamp and cutter is mounted on the left-hand side of the loom adjacent the fabric edge to provide acceptable fringe length without subsequent trimming.

Filling fringe waste reduction

A weaving machine that is used in conjunction with a lever-controlled dobby head, e.g. a Ruti L-5000 with a Staubli dobby head, is provided with an apparatus-coordinating control system for eliminating fabric defects caused by the following operator errors:
