ABSTRACT:
A board stacking machine comprising a feed conveyor for feeding a plurality of boards, precut to a predetermined size, to an accumulator which is displacebly secured at a discharge end of the feed conveyor for storing and releasing accumulated boards maintained in substantially horizontal alignment by the stacking effect in the accumulator and onto an input end of a control feed conveyor. A discharge conveyor is provided for feeding boards from an end section of the control feed conveyor to a feed supply position of a single board feed conveyor. The board orienting station has a delivery conveyor for supporting and transporting the boards in substantially horizontal alignment and in side-by-side abutting relationship. A discharge conveyor feeds the boards to a board holding station which supports a predetermined number of these boards oriented side by side in a board layer thereon, and positions the board layer on a vertically displaceable support with the boards maintained in alignment. A stopper member is actuable to prevent delivery of boards to a stacker. Control devices are provided for positioning a predetermined number of board layers on top of one another to form a squared stack, and the support is displaced each time a layer is placed on the stack.
