Birger Elmgaard Sørensen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7419117
    Abstract: The invention provides an apparatus for winding material. The apparatus includes first and second roll carriages that are each configured to support a roll shaft. At least one of the first and second roll carriages is configured to be rotated by a drive member. The apparatus also includes an engagement roller displaceable from a first engagement roller position where the traveling roller is free of a web to a second, different engagement roller position where the traveling roller is configured to engage the periphery of a roll of web material that is at least partially wound about the roll, a traveling roller displaceable from a first traveling roller position to a second traveling roller position and a cutter where the cutter is configured to cut through the web after the first roll carriage moves from a first roll carriage position to a second roll carriage position.

  • Patent number: 7134859
    Abstract: A plant which serves to produce a nonwoven web of fibers out of a fibrous material, such a cellulose pulp. The plant comprises a hammer mill for defibrating the fibrous material and a forming head for forming a web of fibers on an endless forming wire, which, during operation, runs mainly horizontally, a first transport fan for transporting defibrated fiber to the forming head via a first air duct and a second transport fan to extract nits from the forming head via a second air duct. Furthermore, the plant comprises a separator, which is connected to the second air duct and arranged for separating the nits and the well-opened fiber, a third transport fan for returning the separated, well-opened fibers to the forming head, and a nits-opener for converting the separated nits into well-opened fiber. The separated nits are transported from the nits separator to the nits-opener by means of a fourth transport fan via a fourth air duct.

  • Patent number: 6660215
    Abstract: This invention relates to a plant used to form an air-laid web of fibers and a powder on a running endless forming wire that is air-permeable and operates mainly horizontally, wherein the plant includes a suction unit positioned under the forming wire; a forming head with a perforated base positioned above the forming wire; at least one fiber feed duct using air flow from the fiber source to feed the fiber into the forming head; and at least one powder feed duct to feed powder by means of air flow from the powder source into the forming head.

  • Patent number: 6363580
    Abstract: A fiber distributor for forming an air-laid fiber web on a running endless forming wire which, during operation, in principle is horizontal. The fiber distributor includes a suction unit positioned under the forming wire, a housing positioned above the forming wire and having at least one combined fiber and air inlet, and a base having a number of flow openings, and a number of rotational wings positioned above this base. These wings distribute the fibers along the upper side of the base. The base is designed as a grid with grid bars which taper in a downwards direction. In the flow openings of the grid, a slip is advantageously formed which prevents the fibers from packing together and blocking the openings during operation. The fiber distributor is thus, at a continuous high capacity and is able to form an even and homogenous fiber layer on the forming wire.
