A machine is disclosed for conveying wooden piece such as logs of wood and lumber, in wood transformation industries such as sawmills. The wooden pieces are conveyed in a conveying direction from the front towards the back of the frame of the machine. The machine has several conveying shafts rotatably mounted in parallel on the sides of the frame. Each shaft has a rotating axis about which it is driven in rotation in a direction corresponding to the conveying direction. Several toothed circular plates are mounted on each shaft and extend in a plane crossing the axis of rotation of the shafts. The plates of a shaft are designed to be offset with respect to the plates of an adjacent shaft. Each tooth of each plate are spaced apart from an adjacent tooth by a distance which corresponds substantially to the range of diameter of the wooden pieces and defines a space therebetween for receiving at least a portion of a wooden piece. The teeth of the plates mounted on a same shaft disposed in order to be aligned together. In action, the rotation of the conveying shafts are synchronised together in such a way that a wooden piece inserted between two teeth of the conveying plates of a shaft is conveyed in the direction of rotation of this shaft until a tooth of the plates of an adjacent downstream shaft carries the wooden piece. So the wooden piece is transferred to the adjacent shaft and is engaged and carried between two teeth of the plates of the adjacent shaft. Therefore, the adjacent downstream shaft conveys the wooden piece further with respect to the conveying direction. The machine can be designed in order to convey the wooden pieces horizontally or upwardly.
