Abstract: The present invention relates to a method and apparatus for foam forming, wherein fibrous foam suspension is introduced from the head box ( 78, 178 ) of a production machine to the web forming section thereof. At least one solid material is mixed into the foam in the head box ( 78, 178 ). The method and the apparatus of the invention are particularly suitable for manufacturing various web-like products of cellulose, glass fiber, aramide, sisal, or other corresponding fibre material.

Abstract: Disclosed is a method of producing a non-woven web of fibrous or particulate material comprising: formation of a foam slurry; deposition of that slurry onto a foraminous element having a three-dimensional mold; and formation of a web having a three-dimensional shape that is not substantially planar by removal of foam from the slurry through the foraminous element and drying the web. An apparatus therefor is also disclosed. The method may be used in production a variety of products, including automotive pleated fluid and air filters, pleated heating and/or air conditioning (HVAC) filters, shaped breathing mask filters and bacterial filters, laminated cleaning products with super-absorbent middle layers, such as a mop wipe shape to fit a cleaning mop head, and other products.
