Producing Flakes for Structural Particleboard on a Ringhead Planer.
Abstract
A method was sought and evaluated for making flakes on a ringhead planer (modification of a high-speed planer) by which flakes would be comparable to those made on a disk flaker (about 0.020 by 2 in. by random width). This exploratory method could upgrade the value of the residue from high-speed planers. Matched specimens were cut from typical Construction grade Douglas-fir. Variables were examined: Moisture content, angle of knives in ringhead, angle of cutting edge, position of ringhead in relation to centerline of piece being planed, and cutting speed. Attention was also focused on a design that would permit feed rates of up to 1,000 feet per minute.
