    Abstract: The invention relates to the entire method for arranging parallel yarns from a warp on a cotton lap having passed through a card or a combing machine or other textile machine used for the same purpose, forming a composite lap of parallel yarns and a lap of irregularly arranged untwisted cotton fibrils. The end result is a firm lap in which many of the untwisted cotton fibrils are wrapped coaxially around each so-called carrier yarn, forming the corresponding composite yarn, and the remaining fibrils are perpendicular to the composite yarns, providing the resulting lap with a consistency such that it can both be cut to obtain the yarns comprising an untwisted cotton sheath, and also used for any desired purpose.

  • Patent number: 7938921
    Abstract: A nonwoven composite that exhibits latent elastic properties is provided. The composite is formed from an elastic strand layer laminated to a nonwoven web facing. Latent elasticity may be imparted to the elastic strand layer through the combination of a thermoplastic elastomer and a polyolefin capable of forming semi-crystalline domains among the elastomeric chains. More specifically, the elastic strand layer may be stretched in one or more directions to orient the elastomer chains. Without intending to be limited by theory, the present inventors believe that the oriented state of the chains may be held in place by the relatively stiff semi-crystalline domains of the polyolefin. The stretched elastic strand layer may subsequently be relaxed and bonded to a nonwoven web facing to form the composite. The composite may be later activated (e.g., heated) to shrink the elastic strand layer and provide it with “latent” stretchability.

    Abstract: The invention describes a method and a device (101) for producing a longitudinal fiber web (100), in which fibers (2) are continuously applied, in the longitudinal direction, to a substrate web (6). In a pretreatment section, a relatively high tensile force (F) has to be exerted on the fibers, resulting in a relatively great strain (?). Before the fibers (2) are applied to the substrate web (6), the stress in the fibers is reduced. The drive for the fibers in the pretreatment section is separate from the drive for the substrate web, the transport velocity of the fibers in the pretreatment section being controlled separately as a function of the transport velocity of the substrate web, in such a manner that the transport velocity of the fibers in the relaxed state is substantially equal to the transport velocity of the substrate web in the relaxed state.

  • Patent number: 6692606
    Abstract: Extruded net with at least some strands which melt away upon the application of heat while other strands maintain elastic, or other desirable, properties. This netting is advantageously combined with a fabric in which the low melting strands function as an adhesive, while the high melting strands maintain their designed properties in the final laminate product.

  • Publication number: 20030230371
    Abstract: A method and device for the production of flat ribbon cables is disclosed, in which several metallic conductors are provided one next to the other and spaced apart in one or more planes, within a synthetic material sheath. The electrical conductors are placed on a ribbon-shaped base and secured with a curing synthetic material melt, so that the synthetic material film that lies in the gap between a roller and a shape molding causes the metallic electrical conductors to join and combine into one composite product. This intermediate product is then, within the same gap between roller and shape molding, joined and coated with a synthetic material compound in a plastic state with the result that the conductors are ensheathed on all sides.

  • Publication number: 20030217802
    Abstract: A process for continuous, tailored lamination of aligned composite materials in such a way that either pre-formed or pre-consolidated sheets are made available for subsequent infusion molding or stamping processes, the process comprising the steps of: material placement, consolidation/stabilization, cut and kit, fabrication, and final trim. A tailored blank machine is also described. The blank machine includes a series of material placement heads arranged in a linear or serial fashion along a single moving placement table, wherein each head lays down a single angle of the prescribed stacking sequence as the conveyer passes under the head at a constant speed wherein the angle is proportional to head traverse rate divided by conveyer speed.

  • Patent number: 6632309
    Abstract: A structural member for reinforcement of asphalt and concrete roadways and other products, and which comprises a gridwork of warp strands and weft strands which are disposed at right angles to each other and so as to define an open structure. In one embodiment, the gridwork is impregnated with a thermosettable B-stage resin so as to interlock the strands at their crossover points and maintain the gridwork in a semi-flexible state, and after being applied to the product to be reinforced, the resin is heated to convert the same into a fully cured composite to thereby rigidize the gridwork and reinforce the product. In cases where the product to be reinforced is heated, such as asphalt paving, the heat of the product provides the heat necessary to fully cure the resin in situ. In another embodiment, the resin is fully cured to rigidize the gridwork prior to its being applied to the structure to be reinforced. A method of producing the resin impregnated gridwork is also disclosed.

  • Publication number: 20030173018
    Abstract: A method of securing an elastic strand to a flat substrate or sheet of material moving the elastic strand and the sheet in a converging manner from a first position in which the elastic strand is spaced from the sheet to a second position in which the elastic strand contacts one surface of the sheet. A filament of adhesive is dispensed onto the strand in a pattern configured with adhesive masses coupled by thinner filament sections. The adhesive masses are contacted with the strand when the strand is in the first position. The strand is bonded to the substrate with at least the adhesive masses.

  • Publication number: 20030113489
    Abstract: A longitudinally reinforced liner for cured in place pipe rehabilitation of an existing pipeline having a plurality of high-strength low-elongation fiber bundles disposed between resin impregnable layers of the liner is provided. The bundles of reinforcing fibers are continuous lengths of reinforcing fibers laid out adjacent to each other and parallel onto about one-half of the middle region of the upper surface of the outer resin impregnable layer. An inner resin impregnable layer formed into a tube is laid up against the outer layer and the reinforcing fiber bundles and a plurality of bundles of reinforcing fibers are laid out along the exposed surface of the flattened inner layer. The edges of the outer layer are wrapped around the inner layer and bundles of reinforcing fibers and the secured to form an outer tubular layer with the reinforcing strands remaining in position between the two layers.

  • Publication number: 20030070745
    Abstract: The invention describes a method and a device (101) for producing a longitudinal fibre web (100), in which fibres (2) are continuously applied, in the longitudinal direction, to a substrate web (6). In a pretreatment section, a relatively high tensile force (F) has to be exerted on the fibres, resulting in a relatively great strain (&egr;). Before the fibres (2) are applied to the substrate web (6), the stress in the fibres is reduced. The drive for the fibres in the pretreatment section is separate from the drive for the substrate web, the transport velocity of the fibres in the pretreatment section being controlled separately as a function of the transport velocity of the substrate web, in such a manner that the transport velocity of the fibres in the relaxed state is substantially equal to the transport velocity of the substrate web in the relaxed state.
