ABSTRACT:
An improved method and apparatus for dry forming adhesive coated wood fibers in an airstream in a particular mold apparatus. The invention includes a particular sequence of steps and related apparatus, and permits the manufacturer of a mat of differing cross-sectional shapes but of uniform density. The invention includes the advantageous steps of final curing of the mat off of the main molding apparatus, thus achieving efficiencies in use.
