ABSTRACT:
A method for forming articles such as crates in which sides of the crate extend generally perpendicular to the base of the crate. The method includes forming a layer of loose binder coated wood particles, precompressing selected portions of the layer which form the sides of the crate, bending the precompressed portions upwardly, inserting the so formed layer in a mould and compressing the layer in the mould to form the desired article. The initial layer can be slightly compressed to hold the particles together and the base of the article can also be slightly precompressed but to a lesser extent than the portions which form the sides.
