A timber-conveying method and apparatus according to which a batch of timber is delivered by any suitable delivery structure onto a conveyer. This conveyor provides for the batch of timber delivered thereto an initial path of movement which has with respect to a horizontal plane an inclination, if any, which is small enough to provide for conveying not only of those timber pieces which directly engage the conveyer but also of timber pieces which are on top of the pieces engaging the conveyer. The conveyer provides for the timber a path of movement subsequent to the initial path of movement and inclined upwardly with respect to a horizontal plane at an angle which is substantially greater than the inclination, if any, of the initial path of movement. This inclination of the subsequent path of movement is such that while those timber pieces which directly engage the conveyer will be conveyed thereby along this subsequent path of movement, those timber pieces which are on top of the pieces directly engaging the conveyer will be caused to travel back toward the initial path of movement, so that by the time timber pieces have been conveyed to the end of the subsequent path of movement, the conveyer will convey only timber pieces, one after the other, which directly engage the conveyer. |
