    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 fibre, aramide, sisal, or other corresponding fibre material.

    Abstract: A non-woven mat useful for a wide variety of purposes, including forming reinforced resin products, is produced in a manner having different specific uses of, and advantages over, conventional chopped strand mats and conventional glass tissue. The mat is preferably made by the foam process (but may be made by the liquid process), and at speeds well in excess of 60 m./min., and has a substantially uniform construction even when low density (e.g. 100 g/m or less). At least 20 % (preferably at least 85 %) of the fibers are in fiber bundles with between 5-450 fibers/bundle. The fibers (typically at least 85 %) have a length between 5-100 mm, preferably 7-50 mm, substantially the same as the length of the fiber bundle they are in. The fibers are preferably held in the bundles by substantially non-water soluble sizing, such as epoxy resin or PVOH. The fibers in the bundles typically have diameters of approximately 7-500 microns, preferably about 7-35 microns. The bundles may comprise at least 10 % reinforcing fibers, such as glass, aramid or acrylic.

    CPC classification number: D21F11/002

    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.

    Abstract: The invention relates to a substantially laterally pressure-loaded panel, the side aspect ratio of which is at least 1.5 and said panel being formed of at least two reinforcement layers of substantially unidirectional fibres, i.e. unidirectional reinforcement layers, the predominant orientations of said reinforcement layers forming an angle of approx. +/- 55 DEG - +/- 75 DEG with the longer side of the panel. The panel is preferably constructed of multiaxial reinforcement, the fibres of which are positioned at an angle of approx. +/- 55 DEG - +/- 75 DEG with respect to the longer side of the panel. Panels in accordance with the invention can be used preferably in connection with boat and/or shipbuilding and also in other pressure-loaded tanks, pressure-vessels and other corresponding structures that are subjected to a lateral pressure load.
