  • Patent number: 5622584
    Abstract: A method of making sanitary products giving a high wearing comfort includes the step of forming three superposed interconnected layers (14, 15, 16). The outer layers (14, 16) are made of hydrophobic fibers and the intermediate layer (15) is made of hydrophilic fibers. The top sheet of the sanitary product is constructed of the layer (16), and has flow lines throughout the layer. The flow lines are made by an embossing roller (21) having a pattern of raised ridges. The ridges are provided with a wetting agent which, when applied to the front sheet (16), neutralizes the hydrophobicity of the fibers and provides a pattern of hydrophilic flow lines which allow a body liquid to flow through the top sheet (16).

  • Patent number: 5555801
    Abstract: A double-sided three dimensional embosssed web is provided by passing an uncured paper or plastic web (15), through a nip between an embossing roller (18) and a pressure roller (19), the pressure roller having a smooth and hard surface to create the effect of a double-sided three dimensional embossing on the web. Such double-sided embossing gives the web a good hand and feel and a good drapability, thereby making the method suitable for manufacturing cloth, curtains, diapers and other products which should feel soft and pleasant and which should have a good drapability comparable with that of knitwear and textiles. The embossed web has embossing or impressions (24) provided on two surfaces as a mirror image around a plane of symmetry (23) passing through the middle of the web (15). In the same way raised areas (26) are opposed by raised areas (26).

  • Patent number: 5471712
    Abstract: An apparatus for making a sheet formed fiber product includes at least one fiber distributor (1) having a substantially planar bottom (7) in the form of a wire net, with openings approximately formed as parallelograms; an endless forming wire (2) having an upper and an lower run, the upper run being situated a short distance from the underside of the bottom (7) of the fiber distributor (1), and at least one suction box (3) situated in such a way in relation to the upper run (2) of the forming wire that fibers passing through the bottom (7) of the fiber distributor are disposed onto the upper side (2) of the forming wire in the form of a coherent fiber layer.

  • Patent number: 5416960
    Abstract: A method for the production of a fibrous product containing curled fibers includes applying rectilinear bi-component fibers (17) to the upper side of a raw material sheet (2) before it is introduced into a defibrator (1). Immediately before the introduction a heating is effected. When the rectininear bi-component fibers (17) are introduced into defibrator (1), the beater bars (9) effect a curling effect to provide a raw material including curled bi-component fibers. Hereby it is possible to substantially reduce the manufacturing costs, however, having the effect of curled bi-component fibers in the final fibrous product. Moreover, a good bonding of the fibers is obtained in the final product.

  • Patent number: 5414902
    Abstract: A defibrator which makes it possible to distribute defibrated cellulosic fibers directly onto a forming wire (5) includes ribs (33) extending inside a cylindrical housing (24). The ribs have outer curved surfaces which direct fibers into an area (35) in which beater plates (25). A grate (37) in front of an outlet (30) from the circular housing (24) is arranged at the periphery (35) for the rotation of the beater plates (25). The grate has an interspace between grate bars only allowing fibers to pass through. Accordingly, agglomerates are returned into the working area of the beater plates (25). As the beater plates (25) act several times on agglomerates, it is ensured that only individual fibers pass through the grate (37). Accordingly, fibers are discharged directly onto the forming wire (5) from a discharge opening (2) of the defibrator (1). Preferably, the discharge opening (2) has a width corresponding to the width of the product to be formed on the forming wire (5).

  • Patent number: 5266250
    Abstract: A method is provided of producing fibrous product from cellulosic wood fiber. First, a layer of this fiber material is deposited on a moving wire. A binding agent in an aqueous solution is then added to the fiber material. Next, the fiber material is moved through a superheated oven having a minimal amount of moving air to cause a lively boiling of the aqueous solution. The fiber material is then dried. In one embodiment, a mixture of alkali treated and acid treated fiber material is deposited on the moving wire.

  • Patent number: 4908014
    Abstract: This invention is an extracorporal thermo-therapy device having inlets and outlets being connected in shunt to a human body's blood vessel system, thereby providing the blood with a detour outside the body, thus becoming an integral part of the body's circulatory fluid system. The fluid system includes not only the blood itself but also all other body fluids (through the intra-corporal exchange between the blood and all other body fluids) for example the serum from the lymphatic system. The purpose of the invention is to use the process and device described to generate extracorporal fever in the blood to a level of around 2 C. above normal body temperature everytime it is on said detour, thus activating the body's own immune system by stimulating the production of white blood cells and antibodies. If the device is used to generate extracorporal fever to a level of around 2 C.

  • Patent number: 4787883
    Abstract: An extracorporal apparatus for continuously treating the blood of a patient for diseases such as AIDS and cancer includes connectors for removing a flow of blood from the patient and returning the treated flow of blood to the patient, a separator for separating the flow of blood while outside the patient into a first blood flow portion which is enriched in red blood cells and a second blood flow portion which is enriched in white cells, separate heaters for heating the first and second blood portions so as to stimulate the production of white blood cells and antibodies therein and/or attenuate and kill viruses, and a filter for filtering the first and second blood flow portions after they have been recombined.

  • Patent number: 4202851
    Abstract: A new method of preparing a fire-resistant sheet formed product is disclosed involving the following steps: (1) grinding together a particulate inorganic material selected from the group consisting of crystallized blistered glass, crushed cement clinkers and crushed blast furnace slags, a hydraulic binder and from 10 to 2% by weight of an organic thermosetting binder in a ball mill until the particulate inorganic material has sufficiently disintegrated and the particulate inorganic material, the hydraulic binder, and the organic thermosetting binder are homogeneously distributed to form a dry mixture of particles; (2) subjecting the dry mixture of particles to heat treatment, under pressure, to consolidate and bond the dry particles into a unitary structure to form a sheet; and (3) after release of pressure, treating the sheet with water to set and cure the hydraulic binder.

  • Patent number: 4160004
    Abstract: A method for producing a self-sustaining sheet of essentially cellulosic fibrous material with improved strength wherein a dry-laid web is moistened and then consolidated by passage along a heated consolidating surface wherein the web is held against this surface by one side of a supporting band, against the other side of which at least two spaced apart pressure rolls exert a pressure acting through the supporting band against the web, which pressure is preferably between 150 and 500 pounds per linear inch. The supporting band thereby maintains the web against the heated consolidating roll between said pair of pressure nips.
