pattern warp threads in a latex layer not represented in the figures which is provided on the back of the fabric because of the fact that dead pattern warp threads 5 6 run between the weft threads running one above the other a greater rib height is obtained and therefore an even clearer rib structure in the fabric from fig2 the non rib forming parts of the pattern warp threads 5 6 are not woven through along the back of the fabric these dead pattern warp threads 5 6 married to the tension warp threads 4 are inwoven stretched in the backing fabric a decrease in the pattern warp yarn consumption is therefore achieved in the fabric from fig3 the bottom weft thread 1 of each set of weft threads running one above the other is in relation to the tension warp threads 4 inwoven along the back of the backing fabric while the single weft thread 2 is inwoven along the top the rib side of the fabric the rib forming pattern warp threads 5 6 which are interlaced around these single weft threads 2 are consequently not woven through along the back of the fabric the non rib forming parts of the pattern warp threads 5 6 just as.
