| 摘要 |
The present invention concerns a method for transferring tree trunks (9) or other loose material in a troughed conveyor by exerting to the material to be transferred abrasive forces acting sequentially in transfer direction and in return direction. The abrasive forces acting in the transfer direction are exerted to the material to be transferred simultaneously on both of the partial surfaces (13) between the stationary centre portion (21) and the stationary side surfaces (3, 3'). The abrasive forces acting in the return direction are exerted non-simultaneously as well with respect to the abrasive forces in the transfer direction as with each other. The invention further concerns a respective apparatus.
