         3 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 2 , wherein the yarn-tensioning module includes two carriers with a substantially flat surface which forms a respective outer side of the yarn-tensioning module, and in that said carriers are arranged in a position in which their respective surfaces, viewed in a vertical cross section of the yarn-tensioning module, have an angle of inclination and taper towards each other in the direction of the weaving machine. 
     
     
         4 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 2 , wherein the yarn-tensioning module includes two carriers with a substantially flat surface which forms a respective outer side of the yarn-tensioning module, and in that said carriers are arranged in a position in which their respective surfaces, viewed in a horizontal cross section of the yarn-tensioning module, form an acute angle with a vertical plane which runs parallel or coincides with the plane in which said upright flank is situated, and taper towards each other in the direction of the weaving machine. 
     
     
         5 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 3 , wherein the two carriers with mutually tapering surfaces virtually adjoin each other, so that the yarn-tensioning module viewed in a cross section, has a substantially V-shaped profile. 
     
     
         6 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , wherein characterized in that each warp thread is guided from a yarn store to a yarn-tensioning element in non-tensioned state. 
     
     
         7 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , characterized in that the yarn storage device includes at least two spaced-apart juxtaposed yarn storage units. 
     
     
         8 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , wherein the yarn-tensioning device includes at least two yarn-tensioning modules which are spaced-apart next to each other or one above the other. 
     
     
         9 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , wherein each yarn-tensioning element includes an inlet and an outlet for a warp thread and in that, for every yarn-tensioning element a warp thread supplied from a yarn store is either guided to the inlet on the side of the carrier where the outlet is situated, or is guided through the carrier to the inlet from the side of the carrier which is situated opposite the side where the outlet is situated. 
     
     
         10 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , wherein a yarn-guiding means is provided between at least one yarn store and a yarn-tensioning element and is configured to guide and protect a warp thread along virtually the entire path from the yarn store to the yarn-tensioning element. 
     
     
         11 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 9 , wherein the yarn-guiding means is tubular. 
     
     
         12 . Arrangement of a weaving machine and a yarn storage device with an associated yarn-tensioning device according to  claim 1 , wherein each yarn-tensioning element includes a roller which is driven by a motor and is configured to rotate, in contact with at least one warp thread, in the one or the other direction of rotation in order to move said warp thread in a direction counter to the supply direction of the warp threads, respectively to move the warp thread or to move it concomitantly with the movement or in order to facilitate a movement thereof, in a direction which is identical to the supply direction of the warp threads, in order to increase or decrease, respectively, the yarn tension in said warp thread.
