How do they make plywood sheets?

Plywood is a material manufactured from thin layers or “plies” of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another. All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to form a composite material.
