Abstract
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.
