Shaping-Lathe Roundup Machine Is Key to Profitable Manufacture of Composite Sheathing Panels in Massachusetts Or Maine

A process for producing a superior quality structural sheathing from flakeboard cores and 1/8-inch veneer facings, using 8-foot veneer bolts as raw material, is described. Debarked veneer bolts would be rounded up on a shaping lathe headrig, which would produce flakes of an optimum configuration. Bolts would be peeled to form veneer and the cores flaked in a separate operation. Flakes generated at roundup, veneer core flakes, veneer residues, and panel trim would be pressed into 9/32- to 13/32-inch thick core sheets, which would be faced with the veneer. A proposed plant, located in western Massachusetts or in central Maine, could process 5,000 to 6,000 peeler bolts with an average diameter of 10 inches per day (three shifts) and produce 100 million sq ft of 17/32-inch panel annually. The only residue from the operation would amount to 10 percent by weight of debarked bolts, primarily as sander dust which could be utilized as fuel. Estimated costs and operating capital for such a plant are $23 million; estimated profits are about 36 percent before taxes and about 18-1/2 percent after taxes, based on the entire investment; estimated cash flow is about 28-1/2 percent, $6,520,000 annually, after taxes.
