Figure 24-22A. — Mechanical devices to align flakes. (Top) Top view of laboratory-scale 

 parallel vibrating plates; flakes are admitted to the plates from an overhead distribu- 

 tion chute, not shown, and as they pass through the plates are aligned parallel to 

 them. (Photo from U.S. Forest Products Laboratory.) (Bottom) Finned rolls; strand-like 

 flakes are shown dropping at the left and travelling over and through the power- 

 driven finned rolls to form an aligned mat; see also figure 24-22B. (Photo from 

 Siempelkamp Corporation.)
