  • Patent number: 11559143
    Abstract: A method of manufacturing a mattress that comprises forming a mattress inner core; forming a non-quilted mattress cover; and attaching the non-quilted mattress cover to the inner core without sewing. The non-quilted mattress cover may be formed of a laminate including a polymeric non-woven fabric that may be embossed and cut to include a cover top panel and a plurality of cover side panels that are unitary with and extend outward from the cover top panel. The step of attaching the non-quilted mattress cover to the inner core without sewing includes orthogonally orienting the cover side panels relative to the cover top panel and fusing portions of adjoining surfaces of adjacent cover side panels to each other to form a coffin, inserting the mattress inner core into the coffin, folding non-fused portions of the adjoining surface of the adjacent cover side panels over the mattress inner core, and bonding a bottom panel to the non-fused portions of the cover side panels and the mattress inner core.

  • Publication number: 20140201921
    Abstract: A cushion assembly includes a cover having a perimeter panel providing a perimeter height. Spaced apart cover panels extend between the perimeter panels. The perimeter and cover panels together provide a cushion cavity. A cushion includes randomly oriented fibers bonded to one another to provide a core of a batt that has opposing surfaces. In one disclosed example, the fibers are polyester and include an average length randomly oriented in three dimensions. The core has a thickness that is greater than the average length to accommodate the average length in all three dimensions. The batt includes manufactured, tufted and desired design heights. A tuft extends through the cushion to the opposing surfaces to maintain the cushion in the tufted height, which is less than the manufactured height. The cushion is provided with the desired design height with the tufted cushion arranged within the cushion cavity, the desired design height less than the manufactured height and more than the tufted height.

  • Patent number: 7540307
    Abstract: An inventive machine and method are used for manufacturing fiber articles with a variable density across the article. The machine includes a mold providing a cavity. An inventive cover providing an opening is arranged over the cavity. In one example, the opening is provided on a belt. The size of the opening may also be adjustable. The cover and mold move relative to one another to arrange the opening over multiple portions of the cavity. A fiber feed system deposits fiber material in the multiple portions beneath the opening in varying amounts. Various sensors and other devices may be used to control the positioning of the opening to regulate the distribution of fiber deposited in the cavity.

  • Patent number: 7537818
    Abstract: Acoustically absorptive carpeting includes a primary layer of fibrous material with yarn tufts extending outwardly therefrom and a secondary layer of thermoplastic material that forms a carpet backing. The carpet backing is rendered porous. A substrate of porous material is attached to the carpet backing. The substrate includes a layer of fine fibrous material attached to a layer of coarse fibrous material. The layers of fine and coarse fibrous material each have respective different acoustic impedances. The layer of coarse fibrous material has fibers in an open, loose configuration. The carpet backing is bonded to the layer of coarse fibrous material with a thermoplastic adhesive material such that the thermoplastic adhesive material encapsulates individual fibers of the layer of coarse fibrous material without extending therebetween.

  • Publication number: 20070240810
    Abstract: A machine includes a conveyer that is movable along a generally linear path. Two fiber chutes deliver fiber to the conveyer. First and second heaters and compression devices are used to provide different densities to the different fiber layers. A first heater and first compression device is used to compress a first fiber layer prior to depositing the first fiber layer onto a second fiber layer. The compressed first fiber layer and uncompressed second fiber layer are conveyed to the second heater and second compression device where both layers are heated and compressed. Aesthetic layer may also be applied to at least one of the layers. A third layer may be provided on the first layer opposite the second layer. The compression devices are adjustable by an actuator for processing fiber batts having different thicknesses on the same machine. Adjustable trimmers are used to trim the sides of the continuous fiber batts and cut the batts to a desired width, height and length.

  • Publication number: 20060246799
    Abstract: Sound attenuating laminates for use within vehicles are provided that include a substrate and polyurethane attached to selected portions of the substrate. The polyurethane is non-porous and serves as a barrier to attenuate sound passing through the substrate. Additional non-porous polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound attenuation characteristics in the one or more selected portions. Sound attenuating laminates for use within vehicles are provided that include a substrate and breathable polyurethane attached to selected portions of the substrate. The polyurethane serves as an absorber of sound (e.g., sound generated within a vehicle compartment). Additional breathable polyurethane may be added to one or more selected portions of the polyurethane layer to enhance sound absorption characteristics in the one or more selected portions.

  • Publication number: 20060208379
    Abstract: A method of manufacturing an article having controlled density, such as a decoupler for a vehicle interior trim component, is disclosed which uses an indexing, preferably rotary, apparatus. The method comprises the conveying of materials, preferably fibers, into an enclosure to form a preform having a shape of the enclosure, transferring the preform to a mold on an indexing apparatus where the preform is heated to a temperature such that adjacent fibers bond to one another upon cooling, and moving the mold to a press where the heated preform is molded into a predetermined three-dimensional decoupler configuration. The enclosure has a perforated portion and at least one panel movable relative to the enclosure so as to selectively expose portions of the perforated portion. The density of the preform may be varied as the at least one panel is removed to expose the perforated portion of the enclosure.

  • Patent number: 7055649
    Abstract: Sound attenuating laminates, and methods of making the same, are provided. Heat is applied to a surface of a non-woven, fibrous layer of material to form a stratum of melted fibers having a density greater than that of the remainder of the fibrous layer. The density of the melted fibers is effective in attenuating noise traversing the fibrous layer of material. Upholstery material, such as carpeting, is attached to the surface of the heated fibrous layer. The fibrous layer and upholstery material are then subjected to compressive molding pressure to obtain a desired shape. The compressive molding pressure may further tune the sound attenuating properties of the fibrous layer by selectively changing the densities of portions of the fibrous layer.

  • Publication number: 20060075615
    Abstract: An aesthetic cushion assembly includes an aesthetic layer and a fiber cushion bonded to the aesthetic layer. In one example, the aesthetic layer extends beyond a periphery of the fiber cushion to provide flaps that can be used to secure the aesthetic cushion assembly to a commercial product, such as a chair. The flaps can also be used to form a finished product such as a mattress. The aesthetic cushion assembly can be manufactured using a variety of methods. In one example, the fiber is blown onto the aesthetic layer and the fiber and aesthetic layer are heated together. In another example, the fiber is blown into a cavity and separately heated or a simple batt is generated by non-woven manufacturing methods. The fibers are molded into a desired article shape to form a fiber cushion. The fiber cushion and/or aesthetic layer are then trimmed, if necessary, to provide a finished article shape. The aesthetic cushion can then be shipped to a customer and only requires installation onto a commercial product.
