<p>A method of using a cylindrical conveyor the conveyor belt (2) of which is provided with a plurality of shape-holding rollers (1) to be held in a cylindrical form with overlapped side edges of the conveyor belt. The cylindrical conveyor is driven in a shape having straight running portions and curved running portions to transfer a substance (3) enclosed in the cylindrical conveyor belt. A length of a surrounding contour line in cross-section of the conveyor belt around the substance to be transferred is always maintained substantially constant at any portions of the conveyor so that the overlapping width of side edges of the conveyor belt is always constant at the straight and curved running portions. As a result, it is possible to prevent the substance to be transferred from penetrating between the side edges of the overlapping portion of the conveyor belt. <IMAGE> <IMAGE> <IMAGE></p> |
