  • Patent number: 6778276
    Abstract: A method is provided for sorting white paper from a stream of paper wherein the concentration of white paper is less than the concentration of non-white paper. The method includes identifying the white paper by detecting the presence of an optical characteristic of the white paper as the stream of paper is passed by a sensor. Then the white paper is ejected from the stream of paper by controlling one or more actuators directed against the white paper, and thereby separating the white paper from the non-white paper. The method is particularly applicable to the sorting of white paper during curbside recycling.

  • Publication number: 20040027574
    Abstract: Apparatus and methods are provided for sensing the presence of bright white paper on a conveyor of a paper sorting system. The conveyor is constantly illuminated with ultraviolet light. When bright white paper is present in the inspection zone of the conveyor, it will re-radiate fluorescent light energy as a result of the ultraviolet light. Periodically, the inspection zone of the conveyor is illuminated with a second light source in the visible light spectrum. Light is collected from the inspection zone of the conveyor, including reflected light from the secondary source and including emitted fluorescent light energy as a result of the ultraviolet light falling on bright white paper. Periodically a microprocessor associated with the sensor senses reflected light from the second source to determine whether any object if present on the conveyor. The microprocessor then senses the level of fluorescent light energy being emitted from any object on the conveyor.

  • Patent number: 6250472
    Abstract: The present invention includes devices and methods for handling and sorting paper. Devices for accelerating and spreading paper from a paper input to a sensor are disclosed. Operably thin layers of paper are passed through a sensor at cost effective feed rates. One embodiment of the invention includes a spreader positioned to receive paper from the input and an inclined feed section downstream of the spreader. The inclined feed section includes first and second inclined conveyors to further accelerate and spread the paper. A feed accelerator is operably positioned to receive paper from the second inclined conveyor. The feed accelerator further accelerates and separates the paper. The feed accelerator feeds the paper to the sensor which is operably connected to an ejector downstream of the sensor. Targeted paper is ejected from the paper stream and product paper continues downstream to a product conveyor.

  • Patent number: 5476711
    Abstract: A fiber blending system includes an apparatus and method of forming a mat of cellulosic fibers and synthetic fibers, as well as a mat thereby formed. The method includes the steps of fiberizing cellulosic material into cellulosic fibers in a fiberizer, volumetrically metering a metered amount of synthetic fibers, and injecting the metered amount of synthetic fibers into the cellulosic fibers. The cellulosic fibers are blended with the metered amount of synthetic fibers in a blending chamber to form a fiber blend. The fiber blend is dispersed through a fiber disperser having apertures of a preselected size and shape to provide a dispersed fiber blend. A third type of fiber may also be mixed with the dispersed fiber blend. The dispersed fiber blend is collected as a mat on a fiber collector to provide a mat of blended cellulosic and synthetic fibers. The mat may be thermobonded by a thermobonder and sandwiched between a facing sheet and a backing sheet.

  • Patent number: 5432000
    Abstract: A fiber product comprises dry discontinuous fibers having a starch binder on at least a portion of the fiber surfaces, at least about seventy percent of the starch binder coated fibers being unbonded to one another, solid particles are adhered to the fibers by the binder without the binder entirely coating the particles. The fibers may be air laid into a web or formed into an absorbent structure. Superabsorbent particles are a specific example of the particles which may be adhered to the fibers.

  • Patent number: 4900377
    Abstract: Articles are formed of materials which have at least one layer comprising a mixture of thermoplastic and other fibers. This latter layer may be thermobonded together and then densified along at least a section of the eventual peripheral edge margin of an article to be formed from the material. Thermoplastic material containing cover sheets may also be secured to the core and densified in this manner. The entire eventual peripheral edge margin of the article is typically densified. The material is cut within the densified region or slightly outside the densified region to provide a soft peripheral edge. Absorbent materials may be thermobonded within the layer and surrounded by a densified edge to fix them within the article. The composite materials are used in manufacturing infant car seat liners and other articles. In addition, sections of the material may be densified and provided with weakened areas, such as perforations, to enable users to selectively separate the articles along the perforations.
