In a method and conveyor for conveying a solid material by means of parallel, oblong transfer elements that move back and forth in the direction of transfer, most of the surface of the transfer elements moves in the direction of transfer at the same time and at least part of the surface thereof is inclined towards the center of the conveyor. Pieces of material lying on inclined outermost transfer elements are carried on a lower longitudinal part of the transfer elements, the angle of inclination of the part about the longitudinal axis being smaller than the angle of inclination of the upper part thereof. Thus, the support force exerted by the transfer elements on the pieces lying thereon, and the friction force between them and the pieces lying thereon, increase. At the same time, the support force that is exerted by second transfer elements situated lower with respect to the outermost transfer elements on the pieces lying thereon, and the friction between the second transfer elements and the pieces lying thereon, decrease. |
