Abstract
Methods and apparatus for producing three-dimensional structural members having one flat side from wood fibers utilizing flow deposition of the fibers onto a support. The support includes resilient deformable mold inserts. The mold inserts are formed of silicone rubber and may be blocks of the material, or may be a membrane which can be inflated to form the mold inserts. Pressing is done with a force normal to the support, and the mold inserts create response forces at varying directions to thus shape and hold the three-dimensional finished part. Heat drying also may be used.
