Prototype flaking head smooths surfaces left by headrig or edger chipping heads

Abstract

Flaking heads arranged to follow headrig and edger chipper cheads could smooth machined surfaces and produce high-value flakes of near optimum dimsneions for structural flakeboard. In the proposed concept, eight knives are closely grouped in a 45-degree helix on a cutterhead tipped at 45-degree angle to the direction of workpiece feed. Each knife is set out in cutting radius the thickness of one flake (about 0.015 inch_ from the immediately preceding knife. Thus an eight-knife head would, in each revolution, remove eight flakes 0.015 inch thick and perhaps 1 inch in length while making a cut about 1/8 inch deep, therby removing traces of torn grain caused by chipper knives.
