Apparatus is disclosed for assembling timber output at the delivery end of a feed conveyor in packages of layers. The feed conveyor delivers timber pieces in equally spaced relationship. A transfer device is provided in direct connection to the delivery end of the feed conveyor and includes at least two carrier planes movable individually and after one another in a cyclic path. One carrier plane is always in a phase of its cyclic movement so as to constitute a continuation of the feed conveyor for receiving timber pieces delivered from the conveyor to form a layer. Each carrier plane during said phase of its cyclic movement moves ahead in agreement with the feed conveyor a distance equal to the width of the timber piece during the time the feed conveyor moves a distance substantially equal to the width of the timber piece and the spacing between them until a layer is completed.
