ABSTRACT OF THE DISCLOSURE An apparatus for laying a mat of wood strands, particularly long strands, in the process of producing a composite product such as waferboard is disclosed. In the past it has not been possible to lay long wafers in an oriented mat except by hand. The present invention provides a means for forming a pile of wood strands of substantially uniform depth, a plurality of spike rolls located at one side of the pile of wood strands to pull the wood strands out of the pile and form a uniform curtain of falling strands and a conveyor to force the pile of wood strands against the spike rolls. Beneath the spike rolls are a pair of counter-rotating spreader rolls spaced apart to receive the curtain of strands and having spikes to distribute the strands in an even mat beneath. A horizontal adjustment is provided to position the spreader rolls beneath the curtain and vary the distance between the rolls.
