PCT No. PCT/NO97/00135 Sec. 371 Date Dec. 28, 1998 Sec. 102(e) Date Dec. 28, 1998 PCT Filed May 28, 1997 PCT Pub. No. WO97/45345 PCT Pub. Date Dec. 4, 1997A belt steering assembly for centering of conveyor belts (5) comprises a mechanism with steering rollers (1) and guide rollers (9). In the event of a lateral misalignment of the belt (5), the belt's movement will be transferred from the guide rollers (9) to the steering rollers (1), with the result that the steering rollers return the belt to a neutral position. Preferred ratios are described between different lengths of a lever arm (6) for transfer of the movement. A method for loading of a conveyor belt comprises moving the conveyor belt (5) laterally before loading to a position where the centre of gravity of the loaded material (15) falls on the conveyor belt's central portion (12), and after loading steering the conveyor belt laterally to its neutral position. |
