of which corresponds substantially to the cross section of the profile fabric 26 to be produced the warp threads 4 are kept at the weaving station 20 already in the desired form of the final profile fabric with the aid of the shaping opening 24 and this form is kept by the inserted and tied off weft thread loops 12 fig2 to 4 show cloth holders 22 a 22 b and 22 c having different shaping openings 24 a 24 b and 24 c with circular elliptical and polygonal such as quadrilateral cross sections the cloth holders have a split form along their horizontal mid plane so that a part can be removed in order to make it easier to insert the warp threads however it is also possible to provide for example along the mid plane on one side of the cloth holder an introduction slot not shown in more detail for introducing the warp threads in order to make it difficult for the warp threads to slide out the introduction slot can have a wavy form fig5 shows a longitudinal section through the cloth holder 22 in order to reduce the frictional resistance of the profile fabric in the shaping opening 24 the latter can have a slightly widening cross section in the running direction of the profile fabric the profile fabric 26 emerging from the cloth holder 22 is taken up by means of a cloth take up 28 at which the profile fabric is guided in multiple looping in order that the profile fabric is taken up securely and that deformation of the profile fabric is prevented the cloth take up 28 has two rollers 30 32 which are spaced apart from one another and of which the roller 30.
