A method for removing an incorrectly inserted weft thread on an air jet weaving machine, which has at least one main blowing nozzle in the weft direction and a plurality of relay nozzles, which each have one or more blowing openings and are arranged along a weaving sley, wherein a first drive drives a shed forming device for opening and closing a weaving shed defined by warp threads, wherein the weaving shed is formed by a lower shed and an upper shed, and wherein the at least one main blowing nozzle and the relay nozzles transport the respective weft threads through the weaving shed, and wherein a second drive drives the weaving sley together with a weaving reed arranged on the weaving sley, so that the latter periodically strikes the interlacing point of the fabric, wherein a control controls the first drive and the second drive in such a way that they are operated in synchronism with one another during normal weaving operation, wherein the method comprises the following steps: detecting a weft thread incorrectly inserted into the weaving shed with at least one thread monitor, which generates a corresponding error signal and forwards it to the control, subsequently cancelling the synchronism between the first and the second drive (20, 30) by the control after reception of the error signal, subsequently controlling the second drive by the control in such a way that the weaving reed assumes a first pivot position pivoted away from the interlacing point, and controlling the first drive by the control in such a way that the shed forming device transfers the weaving shed into a first open position by raising the lower shed and lowering the upper shed, the opening angle (α) of which formed by the lower shed and the upper shed starting from the interlacing point is smaller than the opening angle (α') of the maximum open position of the weaving shed reached during the continuous weaving operation, subsequently blowing out and/or suctioning in the incorrectly inserted weft thread on the insertion side or the outlet side of the weft thread and/or mechanically eliminating the incorrectly inserted weft thread from the weaving shed in the respectively said first open position of the weaving shed, subsequently cutting off the incorrectly inserted weft thread on the insertion side, and subsequently removing the incorrectly inserted and cut-off weft thread. detecting a weft thread incorrectly inserted into the weaving shed with at least one thread monitor, which generates a corresponding error signal and forwards it to the control, subsequently cancelling the synchronism between the first and the second drive (20, 30) by the control after reception of the error signal, subsequently controlling the second drive by the control in such a way that the weaving reed assumes a first pivot position pivoted away from the interlacing point, and controlling the first drive by the control in such a way that the shed forming device transfers the weaving shed into a first open position by raising the lower shed and lowering the upper shed, the opening angle (α) of which formed by the lower shed and the upper shed starting from the interlacing point is smaller than the opening angle (α') of the maximum open position of the weaving shed reached during the continuous weaving operation, subsequently blowing out and/or suctioning in the incorrectly inserted weft thread on the insertion side or the outlet side of the weft thread and/or mechanically eliminating the incorrectly inserted weft thread from the weaving shed in the respectively said first open position of the weaving shed, subsequently cutting off the incorrectly inserted weft thread on the insertion side, and subsequently removing the incorrectly inserted and cut-off weft thread.
