    Abstract: A method of producing a drainage grid or network comprising a number of interlocked strips is disclosed which comprises providing a warp direction a plurality of strips having a channel or channels formed longitudinally therein, feeding such strips into a bonding zone wherein a filter material is bonded over the channel or channels, subsequently providing strips of polymeric material transverse to the warp strips and bonding them thereto to form the weft of the network and thereafter collecting the network or grid so produced. The warp and weft may be produced from yarn reinforced polymeric webbing which is heat bonded to give a mesh. It has been found that polyolefin materials, particularly polyethylene, are suitable. Where reinforcing is provided this may be in the form of reinforcing polyester yarns and are preferably inserted in the longitudinal direction in bundles. The filter fabric may also be a thermoplastic material and may be heat bonded, needle punched or woven.

  • Patent number: 6190482
    Abstract: A process of laminating textiles for producing air-permeable or moisture-permeable laminated textile materials involves generating a discontinuous layer of adhesive with a precise pattern of voids by means of temporarily introducing sets of parallel yarns or, alternatively, mesh-like webs in contact with an initially uniform layer of adhesive temporarily carried on a release-coated carrier. After the adhesive layer and the mesh-like web have been pushed into contact with a first fabric layer, the release-coated carrier is stripped away, along with the mesh-like web, from the first fabric layer. The adhesive layer remaining on the first fabric layer will exhibit a discontinuous pattern that is complementary to the mesh-like web pattern. Subsequently, a second fabric, or film, is bonded to the exposed adhesive surface on the first fabric to create a laminated material exhibiting air permeability or moisture permeability.

  • Patent number: 6048426
    Abstract: A method and apparatus of manufacturing a composite material which is light weight and highly damped against vibration. The composite material comprises fibers embedded in a resin matrix wherein the fibers are oriented in a waveform that is substantially continuously variable as to period, amplitude and/or shape. A viscoelastic material is combined with the resin matrix to provide vibration dampening characteristics. The variation in the period/amplitude takes place in a region of the composite structure which is selected to provide optimum strength and dampening characteristics as desired for the particular application. Even without the viscoelastic material, the light weight structure is useful as a pre-preg material from which other composite structures may be formed. Methods of manufacturing the composite material include using multiple, identical cells in which each cell is used to fabricate a fiber, resin matrix and viscoelastic adhesive composite.

    Abstract: The present invention relates to a process for forming a polymeric pre-stretched grid for supporting a structure, such as an earthwork, wherein a suitable polymeric material, e.g. polyethylene, is used to make thin polymer strips by a molding machine, these strips are fully stretched by a pre-stretching machine so as to rearrange long bonds of polymer molecules to form the pre-stretched strips with high tensile strength, then these pre-stretched strips are crossed over each other longitudinally and transversely in line with a pre-set width by a machine (or manually) and the crossings of longitudinal and transverse network plies are united by gluing or hot fusion or otherwise to form a pre-stretched grid.

  • Patent number: 5427167
    Abstract: A pneumatic radial tire for airplanes comprises a toroidal carcass of at least two carcass plies, a tread rubber superimposed on the carcass, and a belt disposed between the carcass and the tread rubber, in which the belt is comprised of a plurality of radially inner belt plies and a plurality of radially outer belt plies, and each of the radially inner belt plies contains cords extending substantially zigzag at a cord angle A of 5.degree.-15.degree. with respect to the equatorial plane in the circumferential direction while axially being bent at both side ends of the ply, and each of the outer belt plies contains cords having a cord angle B larger than the cord angle A. In this tire, the occurrences of standing wave and cut peel off are prevented with the reduction of tire weight.

  • Patent number: 5393364
    Abstract: A method and device (1) for causing a plurality of threads (7) to arrive on support (11) so as to obtain a ply (13) while imparting a nonlinear shape to the threads (7). The threads (7) are caused to arrive with controlled speed on a cylindrical drum (2) in rotation around an axis. The threads (7) are imparted the nonlinear shape by means of teeth (5) which are displaced with respect to others, parallel to the axis of rotation. At least some of these teeth are flexible between a free end in contact with a thread (7) and an anchoring zone. Plies (13) obtained with this method or device, these plies being used for instance in a tire.

  • Patent number: 5380388
    Abstract: For the production of a tight complex having an internal reinforcement or framework and more particularly intended for the production of aerostatic balloons, a nonwoven reinforcement (10) is formed from weft and warp threads arranged in the form of two superimposed layers. To each of the faces of said reinforcement and using a predetermined force is applied a covering film (16a,16b), after bringing it to its pasty melting point on a heating drum (30a,30b). The nonwoven character of the reinforcement makes it possible to preserve the seal of the covering films during complexing. Moreover, the formation of small loops or rings on the edges of the complex obtained in this way makes it possible to introduce connecting cables facilitating the taking up or absorption of stresses.

  • Patent number: 5330604
    Abstract: A method and apparatus is disclosed for manufacturing papermakers or like fabrics wherein preformed apertured fabric bands are joined together in spaced edge-to-edge disposition in a manner to provide substantial uniformity of construction throughout the fabric width. The invention proposed supporting the bands (11, 12) in spaced parallel disposition on a pinned roller (26) wherein the distribution and configuration of the pins (34) matches the apertures in the bands and creating an infill band in the region between adjacent preformed bands (11, 12) by feeding thermoplastic matrix material to the surface of the pinned roller in said region, causing said matrix material to flow into interstices between the pins and to bond with the material of the preformed bands. Reinforcing yarns (13) will be provided in the region between adjacent preformed bands and extending in a direction parallel to the bands and will be embodied within the matrix material of the joined structure.

  • Patent number: 5320702
    Abstract: A press blanket for a press device in a paper making machine, or the like, is formed of an elastomeric blanket material and fully embedded layers of reinforcement threads. The radially inner layer is formed of longitudinal threads which extend parallel to the axis of the press blanket. The radially outer layer is formed of circumferential threads which are wound in the direction of blanket motion and are wound generally helically. The threads are fully surrounded by the layer of homogeneous elastomeric material, that is formed from a single pouring. The circumferential threads have a diameter of at most 1/500 of the outside diameter of the fully rounded press blanket. In a unit area of the press blanket, the tensile strength of the circumferential threads is at least 40% greater than the tensile strength of the longitudinal threads.
