    Abstract: The invention is directed to fabric-based inserts and layers for use with tires in order to provide an improved level of puncture resistance to the tire. Disclosed embodiments of the invention include tire anti-puncture layers including puncture-resistant layers that comprise a single or multiple layers of fabric. Preferably, for low cost and low abrasion, the puncture-resistant layers comprise fibers having a tensile strength or tenacity of less than about 15 g/denier. In some preferred constructions, especially where the puncture-resistant layer comprises a single layer of fabric, the puncture-resistant layer comprises a high cover factor, tightly woven fabric, for example having a round packed cover factor of at least about 40% of full in the warp direction and at least about 65% of full in the fill direction. In other embodiments, especially where the puncture-resistant layer comprises multiple layers of fabric, lower cover, less tightly woven woven fabrics can be used, or, alternatively, non-woven fabrics such as knitted or felted fabrics (felts) can be used. Some such preferred, less tightly-woven fabrics are woven from untwisted yarns, enabling the fibers or filaments comprising the yarns to spread out into a tape-like configuration under compression, thereby increasing the effective cover factor and level of puncture resistance over that predicted from the round packed cover factor. A nulltaped fiber densitynull calculation is presented for predicting the effective cover factor of such taped-out woven fabrics, and certain preferred embodiments of such fabrics have a taped fiber density of at least about 80% of full in at least one of the warp and fill directions. In some embodiments, the puncture-resistant layer, or one or more layers of fabric comprising the layer, are coated with polymeric coatings to increase the level of puncture resistance. In some embodiments, the tire anti-puncture device is configured as a separable strip that can be placed within a tire to act as a liner. In other embodiments, the puncture-resistant device is incorporated within the cross-section of the tire body itself. While the tire anti-puncture device in some embodiments comprises just the puncture-resistant layer, in other embodiments, one or more low abrasion layers can be added to isolate and protect the tire and/or inner tube, if present, from the puncture-resistant layer. Such law abrasion layer(s) are particularly useful for embodiments involving puncture-resistant layers coated with polymeric coatings containing abrasive fillers, which can serve to increase puncture resistance but tent also to increase abrasiveness of the puncture-resistant layer.

    Abstract: A carpet in tile or roll form is produced using an open mesh reinforced foam layer with foam nodules. The carpet is produced having a primary backing through which carpet fiber bundles are tufted and a precoat layer which locks the tufts in place to prevent easy extraction of the fibers so that a tufted face and a relatively smooth back face are provided. The foam layer with foam nodules is brought into intimate contact with the relatively smooth back face, and is substantially permanently adhered to it producing a carpet tile or roll that is substantially prevented from curling or doming (or they are significantly reduced) and may be installed without adhesive if desired. Adhering may be practiced by using a non-fused adhesive formulation which is subsequently fused at a low temperature (about 310.degree. F. or less), or by forcing the foam layer with foam nodules into contact with the carpet back while the hot melt backing is still in a fluid form, or by use of a thermoplastic layer between the carpet and foam sheet.
