摘要:
A weaving machine for producing a woven fabric has a shedding device to form a loom shed of warp material, a weft insertion device for inserting a preferably tape-shaped or band-shaped weft material into the loom shed, a drawing-off device for drawing off the finished fabric in a drawing-off direction, fabric movement device for moving the fabric back and forth in the warp direction to bring the last inserted weft material into contact with the binding point or fabric edge. A shed limiter device limits the opening of the loom shed from above and below the warp, and is movable back and forth in the warp direction. The shed limiter device only loosely bounds the fabric and essentially without actively clamping or pinching or contacting the fabric and/or the last inserted weft material, at least while moving in the direction opposite the drawing-off direction.

Weaving machine (1) for producing a woven fabric (9) with shedding means (4) for alternately raising and lowering warp material (3) for forming a loom shed (5), with weft insertion means (6), which are arranged stationarily in the warp direction in a weft insertion zone (14), and which are for inserting a preferably tape-shaped or band-shaped weft material (7) into the loom shed (5), with drawing-off means (8) for drawing off the finished goods or woven fabric (9) in a drawing-off direction (AR), as well as with means (13, 10) for the fabric movement in the warp direction, by means of which the fabric edge (12) is moveable back and forth in a goods movement range (WB) between a downstream initial position (AG) and an upstream collecting or pick-up position (AH), in order to bring the respective last inserted weft material (7) into contact with the fabric edge (12) in the pick-up position (AH), characterized in that furthermore upper and lower limiting means (16) are provided, which limit the opening of the loom shed (5), in that the limiting means (16) are movable back and forth in the warp direction within a limiting means movement range (BB) between an upstream end position (EP2) and a downstream end position (EP1), and in that the limiting means (16) are moveable at least contrary to the drawing-off direction (AR) essentially without contact with the goods or woven fabric (9) and/or a last inserted weft material (7).

A gripper head for a loom is of lightweight construction and has a weft thread clamp with a stationary pad and a movable pad. The former is directly mounted to the gripper body. The latter is mounted through an adjustable spring to the gripper body, whereby the clamping force is adjustable.

An air nozzle weaving loom has a prenozzle alignment arrangement for the weft yarn picking. Several prenozzles (8a) having respective blow pipe (8b) are accommodated in a prenozzle block 9 according to an order system (geometric configuration) corresponding to the order system (geometric configuration) of main nozzles (5a) in the main nozzle block (6).
