Abstract
Lengths of weft thread are sequentially inserted in sheds formed by a series shed weaving machine. Weft thread is continuously supplied with a fluid flow. By reversing the flow direction of the fluid flow or deflecting the weft thread, a thread loop is formed outside a weft distribution apparatus of the weaving machine so that the weft thread remains taut inside the weft thread distribution apparatus. A nozzle arrangement in which the fluid flow direction is reversible or a weft thread clamping and deflecting arrangement are used to form the loop and maintain the weft thread taut.
