Setting Or Embedding Tufts Or Discrete Pile Elements Onto Backing (e.g., Rugs, Brushes, Etc.) Patents (Class 156/72)
  • Patent number: 5989368
    Abstract: A position detector senses an undulating pile tuft edge position of a carpet as it is processed in a carpet making machine by detecting attenuated light passing through the carpet's primary backing material to determine the exact position of the carpet's undulating pile tuft edge at any given time. Sensor signals from the detector are digitally filtered through one pole cascaded filters to produce an average pile edge position signal which, in turn, controls actuators for secondary and primary backing material guide rolls to not only center the carpet for aligned entry into the carpet machine's tenter, but also apply the secondary backing material to the primary backing material at a precise position.

  • Patent number: 5981035
    Abstract: A method is disclosed for sealing and bonding the seams and edges of resilient and other types of floors, whereby specially formulated hot-melt sealants/adhesives are applied in molten form at the flooring installation site using a heated gun equipped with a specially designed tip. The hot-melt sealant/adhesive flows into and completely fills the seam and bonds to the edges of the flooring producing a bead of material that extends above the surface of the flooring. The specially designed tip facilitates this process by guiding along easily in the groove of the seam or joint and directing the molten sealant/adhesive accurately into the seam. The tip allows the seam or joint width to be very narrow and enhances sealing and adhesion by imparting heat to the edges of the flooring material. Upon cooling, a spatula knife or other appropriate tool is used to skive off the excess bead of material leaving it flush with the flooring.

    Abstract: A method for producing a heel mat-attached floor rug for a motor vehicle. A floor rug proper is prepared which has been previously compression-molded to have a three-dimensionally projected portion. Then, the floor rug proper is put on a lower die of a depression-molding device in such a manner that the three-dimensionally projected portion of the rug proper neatly covers a projected portion formed on a shaping surface of the lower die. Then, a heel mat of thermoplastic material is put on a shaping surface of an upper die of the compression-molding device. The shaping surface of the upper die has a depressed portion which is shaped to neatly receive the projected portion of the lower die. Then, the upper die is pressed against the lower die having the heel mat and the floor rug proper put therebetween. Then, a lower surface of the heel mat is melted, by means of high frequency induction welding, thereby to bond the heel mat to the floor rug proper.

    Abstract: The floor mat of the present process is a pliable multilayer structure having an upper face layer and a base layer. The base layer has a main body section bordered by an edge section. Preferably, the main body section is relatively thin and the edge section is relatively thick. A surface of the base layer is adapted to confront flooring overlaid by the mat. The edge section has a channel extending longitudinally thereof, and preferably opening from the bottom surface of the edge section. A portion of the main body section can have a channel molded therein such that a portion of the main body section is disposed above the remainder of the main body section to provide a decorative and aesthetically pleasing design in the main body section.

  • Patent number: 5605108
    Abstract: The invention is directed to a method of tufting and molding a carpet module which is sized and shaped to fit the interior of a motor vehicle to form its floor carpeting. The method includes tufting the module in such a manner that selected areas have pile tufts arranged at a lower densities than the selected high density area. This construction provides that the selected high density area has the greater resistance to wear and the remaining areas have selected lesser resistance to wear while the entire module maintains substantially a uniform appearance.

  • Patent number: 5567257
    Abstract: A process for forming a bonded pile fabric of enhanced stability using low levels of adhesive is provided. In the process pile forming yarn is tacked by heat fusion an open weave base layer prior to the application of adhesive. The adhesive which is preferably a low viscosity latex is applied through an open weave base layer to further bond the pile. An apparatus for making the bonded pile fabric is also provided.

  • Patent number: 5567256
    Abstract: A cotton room-size rug, having dimension between 3 feet.times.5 feet, and 12 feet.times.15 feet, is made from a heat set blend of about 70-90% cotton fibers and about 30-10% low melting temperature polyester fibers. The polyester impregnates the cotton fibers to give them enhanced properties. The fibers are tightly tufted to a primary backing, and latex adhesive connects the primary backing to an open weave polypropylene secondary backing. A stain resistant finish is applied and the sides serged, and fringe attached. A cabled 3.0/2/2 yarn configuration is preferred.

  • Patent number: 5552010
    Abstract: As a method for producing a tile carpet having a a lining layer, there is provided a means for obtaining a tile carpet superior in the uniformity of thickness and adhesion of the lining layer and also superior in all of standing stability, shape and dimensional stability and durability, in high applicability of a sealing material in carpet cloth and a lining material and that in high production efficiency. The method of the present invention for producing such tile carpet comprises applying a heat-melted, amorphous olefin polymer composition (11) onto a travelling endless belt (3), then laminating onto this coating surface a carpet cloth (1) which has been sealed beforehand with an amorphous olefin polymer composition (7), to obtain an integral laminate, thereafter cooling the laminate forcibly using a cooling plate (14), separating the laminate from the endless belt (3) and cutting it into a tile shape.

  • Patent number: 5547731
    Abstract: A process for producing a needled multilayered carpet is described in which an intermediate layer (6) containing thermoplastic film material is arranged between a layer of backing (5) and a top layer (7). The three layers are bonded together into a carpet by means of a process of needling through fibers (9). The intermediate layer (6) is formed by lumpy, three-dimensional plastic film material (8), and the needled fibers are tightly integrated into the intermediate layer (6) by the influence of temperature.

  • Patent number: 5543195
    Abstract: A fabric which prevents outerwear from being noticed, heard or smelled by prey when worn. The fabric includes a flocked woven substrate with flattened flock fibers with the fibers adhered to the substrate. The substrate is quiet and soft. Preferably a printed layer is transferred on said flattened flock fibers and preferably is of a camouflage print pattern. The substrate is drapeable as an apparel item and more abrasion resistant than foamed knitted fabrics. Further the fabric is resistant to burr retention, wind and rain.

  • Patent number: 5540968
    Abstract: A cushioned carpet tile is provided. The cushioned carpet tile includes a primary carpet fabric having a plurality of pile-forming yarns projecting from one side thereof. A mass of polymer cushioning is dispersed on the side of the primary carpet fabric from which the pile-forming yarns do not extend. A heat-fused nonwoven backing of polyester and polypropylene is disposed on the bottom of the polymer cushioning. The ratio of polyester to polypropylene in the nonwoven backing is between about 0.43 and about 2.3.

  • Patent number: 5529650
    Abstract: Processes for the formation of flocked automotive molding members of the type adapted to border windshield and door windows are disclosed. The processes include coextrusion of a thermoplastic polymer and reactive hot melt adhesive in a common die orifice or head onto a profiled metal strip. The hot melt provides an adhesive layer for subsequent flock adherence to the thermoplastic polymer. The hot melt is moisture curable, thereby eliminating need for a curing oven or the like downstream from the flocking station.
