As shown in FIG. 3, three first shape retention frames (7) arranged in a regular hexagonal shape and six shape retention rollers (8 ') on both sides thereof are vertical. One second shape retention frame (9) arranged in such a regular hexagonal shape is arranged so as to be alternately repeated in the forward direction (and / or return path) of the conveyor belt (1) at an appropriate interval. Further, in the direct feed section (B), the first shape retaining frame (7) and the second shape retaining frame (9) similar to the above are alternately arranged one by one.

大である。In the first shape-retaining frame (7) shown in FIG. 2, the upper and lower shape-retaining rollers (8) and (8) on the right side are the center of curvature (0) of the feeding portion (A), Since the straight line (L) connecting the center line (C) of the pipe formed by rolling the conveyor belt (1) is a boundary, they are adjacent to each other vertically and symmetrically with respect to the straight line (L). When the conveyor belt (1) is pulled to the right side in FIG. 2 due to the belt tension, the shape-retaining rollers (8) and (8) are
It comes into contact with the conveyor belt (1) on the pipe in a V-shape and generates a large blocking force against the twist of the conveyor belt (1).
However, on the other hand, the running resistance to the conveyor belt (1) is large.

The point where the same straight line (L) as above and the outer peripheral surface of the pipe intersect
In (P), the vertical shape-maintaining roller (8 ') is moved to the conveyor belt (1).
It presses against the outer peripheral surface of the belt and directly receives the belt tension (which is applied in the same direction as the straight line (L)), and the shape-retaining rollers (8 ') and (8') above and below the belt are evenly distributed on the conveyor belt (1). Since it is pressed against, the running resistance of the conveyor belt (1) can be reduced and the effect of keeping the conveyor belt (1) in a perfect circle is great. On the other hand, the force to prevent the twist of the conveyor belt (1) is small.

防止効果を局部的に高めることができる。(D) According to a second aspect of the present invention, there is provided a shape-retaining member having two shape-retaining rollers which are symmetrical with respect to a straight line connecting the center of curvature of the bending portion and the center of the pipe. In the set of rollers, when the conveyor belt is pulled by the belt tension, the two shape-maintaining rollers form a V shape and are pressed against the conveyor belt, so that a large twisting prevention force is obtained. In particular, as in the embodiment, in the bending portion, a set of shape-maintaining rollers having a large twisting prevention force but a large running resistance can be distributed, but a running resistance can be reduced, but a set of shape-keeping rollers having a small twisting preventing force can be distributed. If they are arranged alternately, the effect of preventing twisting can be locally enhanced particularly in the bending portion where twisting is likely to occur.
