Method and apparatus for manufacturing fiber-reinforced, foamed paperlike products

摘要

A method for manufacturing products with a blown foamy structure, starting from a mass comprising at least natural polymers such as starch and fibers, in particular natural fibers, wherein the mass (M, S) is passed under pressure into or through a mould and the mass (M, S) is heated in the mould in a manner such as to give rise to gelatinization and cross-linking of the natural polymers, with the fibers extending through the product, while the mass prior to the introduction into the mould has a temperature which is below the gelatinization temperature and in the mould is brought at least to the baking temperature.
