of distance x from the opening 12 of the entraining nozzle 2 by distributing the nozzles along the reed 1 in the shed of warp yarn b and by distributing the entraining nozzles 2 into the two systems as shown in fig1 and 2 and 4 a stabilized carrying jet field a is formed as the result of the entraining jets 18 of both the preceding and following entraining nozzles 2 by a carrying jet field a formed in that manner the weft yarn b is drawn along the reed 1 being discontinually supported by its dents 20 as shown in fig6 the stability of the motion of weft thread b along reed 1 is secured so that it avoids the boundary layer of the carrying jet field a which is braked by the reed dents 20 of the reed 1 but the boundary layer thus tending to grow and disturb the stability of the carrying jet field a the growth of the boundary layer of the carrying jet field a along reed 1 is avoided by exhaustion of a part of the fluid from the boundary layer of the jet field a behind reed 1 such exhaustion of the fluid from the boundary layer of the jet field takes place through the gaps between the dents 20 of reed 1 the thickness of the boundary layer of the jet field a can be controlled by changing the acute angle u03b1 of axes 13 of.
