Temperate Forest Foundation: Making Plywood

Below is a general outline of the steps that go into making plywood.

Debarking-Bark is removed from the incoming logs. Bark is used to generate steam in the drying process.
Cut-off Saw Outfeed-Logs are cut to 8.5 foot lengths.
The Steam Vats-Logs are soaked in a chemical solution to condition them for peeling.
Lathe-Logs are peeled into 1/6, 1/8, or 1/10th inch veneers. The lathes peel at a rate of 1100 ft/min.
Clipper-A rotary knife cuts the veneers into 27 x 50 inch sheets
Green Chain-Veneers are sorted according to moisture content into; heart, sap, heavysap
Green Stacker-Veneers are stacked for drying
Dryer-Veneers are dried for 10-13 minutes to 4-8% moisture content. The dryer uses bark to create steam for drying.
After the Dryer, dried veneers are sorted by Grade and Stacked
At the Raimann Machine, knots in the veneers are replaced with patches and the resulting veneers are graded again.
Core Composer-Veneers are cut to 8 x 8 foot sheets before heading to the...
Lay-up Line-where veneers are assembled into 5-ply sheets to make the finished plywood. Veneer layers (or plys) are arranged with the grains of alternate layers running perpendicular to each other.
Hot Presses-Assembled boards are individually stacked and inserted into the presses where they are cured by 90psi pressure and 300 degree F. temperatures into plywood.
Patch Line-fills holes in the pressed plywood boards with polyurethane.
Saw Line-Panels are graded and cut to 4 x 8 sizes
Sander Out-feed-panel faces are sanded for smoothness
Sander Bander-Panels are strapped together for shipping.
