The invention relates to a toothed belt (1, 1 ') made of rubber or rubber-like plastic for belt drives with at least one back roller (10), which has a tension cord (12) and a fabric (15) on the back of the toothed belt, the fabric (15) having the belt body is vulcanized together by a vulcanization process. DOLLAR A The fabric (15) on the toothed belt back has an elongation at break, measured on a 10 mm wide fabric strip, of more than 50%, the tension value of the fabric (15) at 5% elongation, measured on a 10 mm wide fabric strip, is at least three times as high in the transverse direction of the belt as in the longitudinal direction of the belt, and the fabric (15) has an axisymmetric weave pattern of at least 80% of the belt width consisting of two perpendicularly crossing thread systems made of warp and weft threads, the axis of symmetry of the weave pattern on the back of the belt between the side Edges of the belt back lies and their direction deviates from the direction of the edges by an angle of not more than 5 ° and the weft threads of the fabric (15) run parallel to the axis of symmetry. |
