Manufacture of corrugated waferboard
1989
Bach, L.
Improvements in the performance characteristics of flat waferboard and oriented strandboard have been attained by optimization of such parameters as wafer geometry, resin content, resin type, panel density additives, and others. However, existing manufacturing technology would appear to have exhausted these possiblities for increasing structural strength. In an attempt to improve the flexure strength characteristics of waferboard panels, the Alberta Research Council and B.S.L. Machine Limited of Edmonton, Canada, designed and constructed a pilot plant press and a process for the industrial manufacture of corrugated waferboard. A unique press platen assembly was built with a working surface that can be mechanically converted between planar and corrugated configurations to overcome the problems associated with a fixed male/female press platen system. Using this assembly, corrugated waferboard (called Waveboard by the Alberta Research Council) with approximately 28 times greater stiffness and about 7 times greater bending strength than flat waferboard (of the same thickness and weight) was manufactured. The use of corrugated waferboard in construction could extend practical design spans far beyond those possible using the flat waferboard (and oriented strandboard) produced today.
