  • Patent number: 11066251
    Abstract: A conveyor for transporting a board along a path in a transport direction has an upstream section, a downstream section aligned with the upstream section and defining therewith a horizontal support plane, and a center section between the upstream and downstream sections. The center section is movable from a pass-through position aligned and level with the upstream and downstream sections to an offset position spaced therefrom horizontally or vertically. A platform underneath the center section is moveable vertically, and a lift moves the platform vertically between upper and lower positions. Hooks or grab can, when the center section is in the offset position and the platform is in the lower position, either pull a board off the platform and onto the downstream section or guide and deposit a board from the upstream section onto the platform.
