An auxiliary nozzle for an air jet loom is configured as straight tubule closed and tapered blade-like at its free end and moveable with the loom batten into and out of the formed sheds. At least one blow aperture near the closed end of the tubule is provided in the shape of a slot extending essentially transverse to the tubule axis. The slot has a width not exceeding 0.8 mm and lateral walls configured so that the least or critical cross-section is bounded at least on one side by an edge having a thickness not exceeding 0.2 mm. If one edge is provided, it is located on the lower side of the slot toward the air supply and away from the closed end of the tubule. Various aperture configurations are disclosed.

Auxiliary nozzle for air jet loom

A method for the control of auxiliary nozzles or blowers for the insertion of a weft thread in air jet weaving looms wherein several auxiliary blowers and/or groups of auxiliary blowers (1-9; 45; 46; 47; 50) are distributed along the shed (10) of the weaving loom comprising controlling a first row of auxiliary blowers and/or groups of auxiliary blowers (1-6; 45; 47) in such a way that these auxiliary blowers and/or groups of auxiliary blowers (1-6; 45; 47) create a basic air stream which achieves the guiding of the weft thread along the shed (10) and the control of a second row of auxiliary blowers and/or groups of auxiliary blowers (7-9; 46; 50) in such a way that these auxiliary blowers and/or groups of auxiliary blowers 7-9; 46; 50) create an additional air stream which mainly creates a pulling force of the weft threads along the shed.
