摘要

Belt assembly (10) for a machine for producing and / or final treatment of a fibrous web, comprising:two cylindrical guide members (11, 31),a belt (5), which is an endless loop around the two cylindrical guide members (11, 31) is formed around, wherein the strip by the cylindrical guide members (11, 31) in a strip movement direction (b) is guided and, by way of the cylindrical guide members (11, 31) in the strip movement direction (b) passes, anda detecting device, which is adapted to a voltage of the belt (5) in the strip movement direction (b), whereinthe detecting means comprises a sensor arrangement, which is adapted to the voltage of the belt (5) in the strip movement direction (b) of edge sections of the belt (5) to measure,the belt assembly (10) of the further including control means, which is adapted positions of the axial end sections of at least one of the cylindrical guide members (11, 31) both in a horizontal direction, which is perpendicular to the axis of the roller (31) is, as well as in a vertical direction which is perpendicular to the axis of the roller (31) and perpendicular to the horizontal direction is, independently, to be adjusted in such a way that the position of the belt (5) with respect to the at least one guide roller (31) is controlled,the control device is adapted to the positions of the axial end sections of both in the horizontal direction as well as in the vertical direction on the basis of the voltage, which is measured by the sensor array, independently, andthe band (5), a heat-conducting strip which preferably is made of metal, and is impermeable to fluids.
