    Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.

    Abstract: An infilled artificial surface has natural grass-like play characteristics due to the use of two distinct groups of fibers extending upwardly from a backing, and a stabilizing fill material residing on the backing, with a first upper group of fibers simulating grass plants and extending above the infill and a second lower group of preferably texturized fibers extending upward from the backing to the top of, but not above, the fill. With this structure, substantially all of the fill material is stabilized within the vertical level of the second lower group of fibers. This second group of fibers “locks” the fill material in place and helps to promote consistent and uniform play characteristics which closely simulate natural grass, with a “foot feel” of natural turf. This structure also improves the durability of this playing surface, compared to prior infilled surfaces.

  • Patent number: 6517915
    Abstract: A decorative composite stone material, the finished face of which is more durable and requires less maintenance than previous composite stone products. The decorative component of the aggregate material is specifically limited to a hard aggregate of enhanced aesthetic appeal, specifically, to granules of quartz or other transparent or semi-transparent material having a Mohs index of at least 7, naturally occurring or synthetic. The granules of quartz are adjustably coated with a metallic, ceramic, plastic or other film, mixed with a binder, cast, and cured. In the surface finishing step, granules close to the surface are ground to create an exposed facet through which light passes in and out, the coating providing reflective properties that add color, sparkle, glitter, metallic or other visual effect to the hard composite stone surface without compromising the hardness and durability of the product.

  • Patent number: 6472041
    Abstract: A monolithic surfacing system is capable of being applied to almost any stable, compacted base which is capable of supporting the weight of the system. The system provides an economical solution to the cracking and degradation which is experienced with conventional artificial surfaces which are exposed to the elements or extended wear. The surfacing system includes a bottom layer comprised of a pile fabric having a flexible backing and a plurality of upstanding pile elements. Each of the pile elements has an upper and a lower end. The pile elements are in-filled with a quantity of in-fill material which is sufficient to form a layer of substantially uniform density extending from the flexible backing of the bottom layer to substantially the upper end of the pile elements. A quantity of binder is added to the system, and a top layer comprising a wear coating having an upper and a lower surface is applied to the in-fill material and binder.

  • Patent number: 6338885
    Abstract: A synthetic grass surface comprising widely spaced rows of ribbons and the ribbons having a length about twice as long as the spacing between the rows of ribbons. A particulate material is laid on a matrix of the synthetic grass, and the thickness of the particulate material is as least two-thirds the length of the ribbons. The strips of ribbons are attached by strips of bonding material applied to the back of the matrix or mat. The strips of bonding material are spaced apart and leave areas of mat which are uncoated, thereby providing improved drainage.

  • Patent number: 6299959
    Abstract: The improved top dressed synthetic turf according to the patent invention provides thatch like fibers to retain top dressing and particularly the rubber or resilient particles in the dressing. The grasslike surface is formed by polyethylene co-polymer slit fibers more than two inches in height tufted through a fiberglass reinforced backing. The thatch zone fibers are dense and texturized so that they will contract to only about one inch in height after curing.

  • Patent number: 6296919
    Abstract: This invention relates to a cushioned floor covering article wherein the mat includes a tufted carpet placed on the top side of a foam rubber sheet and at least one foam rubber protrusion integrated within at least a portion of the bottom side of the foam rubber sheet. Such an article provides effective removal of moisture, dirt, and debris from the footwear of pedestrians through the utilization of a carpet pile component. Furthermore, the utilization of a foam rubber backing also allows for either periodic heavy duty industrial-scale laundering in such standard washing machines or periodic washing and drying in standard in-home machines, both without appreciably damaging the inventive floor covering article, such as a floor mat. Additionally, the presence of integrated foam rubber protrusions within the mat structure provides an effective cushioning effect for pedestrian comfort as well as a means to prevent slippage of the article from its contacted surface.

  • Publication number: 20010009710
    Abstract: The present invention provides for an article of manufacture, such as a floor covering, formed by an improved process for recycling waste polymeric material comprising a mixture of waste polymeric material wherein the waste polymeric material includes from about 0 to 40 percent aliphatic polyamide material; granulating and densifying the chopped mixture into fragments smaller than the original size of the waste polymeric material; and extruding the ground mixture at a temperature that does not exceed the temperature at which the largest portion of polymer based material decomposes.

  • Patent number: 6221445
    Abstract: An artificial turf is disclosed which comprises an outer artificial grass layer having a generally uniform exterior playing surface. A deflection layer is disposed below the artificial grass layer. The deflection layer has a prescribed height to provide resiliency for absorbing impact shocks from foot traffic and playing on the artificial grass layer. The deflection layer has a plurality of interstices providing open passages for water drainage; and loose particles are dispersed into the interstices of the deflection layer up to a prescribed level to provide stability and enhance shock absorption so that the deflection layer deflects when the artificial grass is impacted to assist in absorbing the impact and maintain normal playing action of the playing surface of the artificial grass layer.

  • Patent number: 6001493
    Abstract: A first pattern of bumps and a second pattern of bumps are formed on a substrate (10) with bumps (14,15). During a transfer process, only the bumps (14) of the first pattern of bumps are transferred to pad extensions (20) of a device (17). The bumps (15) of the second pattern of bumps are not affected by this process and can be later transferred to a second device.
