The conveyor system (10) comprises a transverse conveyor and a linear conveyor (11) the conveying direction (14) of which include between them an angle of substantially 90.degree. in a horizontal plane. The transverse conveyor is arranged upstream of the linear conveyor (11) in the conveying direction. It is adapted for feeding the timber products in a direction perpendicular to their longitudinal extension and for transferring them to the linear conveyor (11) at a transfer station. The linear conveyor (11) comprises, in the area of the transfer station, at least one linear conveyor (28) gripping the downstream end of the timber product, at least one vacuum jack (26, 27) acting on the middle portion of the timber product from below, at least one jack roller (50, 51, 52) arranged above the vacuum jack (26, 27) and capable of being pivoted in upward direction, away from the timber product, and a sequence control unit for actuating the transverse conveyor, the linear conveyor (28) and the jack roller (50, 51, 52) (FIG. 1).
