Figure 24-22B. — Oriented-strand board mat formation. (Top) Side elevation of forming 

 head and finned rolls which orient the strands; since most structural flakeboards have 

 three layers, three or four heads are required to form the complete mat. (Bottom) Mat 

 of oriented strands emerging from the former. (Drawing and photo from Siempel-
