Withdrawal roller conveyor is a special roller conveyor which is used to separate the side boards from the centre boards. It is installed behind the rip saw. The construction of the conveyor consists of special rollers, which are larger in diameter and smooth in the middle and smaller in diameter on the ends where the withdrawal spiral is welded on. The centre boards are guided through the centre of the conveyor by means of separating plates. The separating plates may be adjusted by hand, servomotor or servo-hydraulic cylinder. The side boards are separated and removed to the sides. The drive of rollers is secured by means of an electric motor and a drive chain.
