  • Patent number: 11313062
    Abstract: An apparatus and method for applying a first web to a base web in a nonlinear pattern as the base web is advanced in a machine direction in contact with a back-up roller are disclosed. The apparatus can include a guide roller and a guide roller translations system. The guide roller can be configured to define a nip with the back-up roller. The guide roller translation system can be configured to allow the guide roller to move with respect to the back-up roller to control the position of the nip to allow the first web to be applied to the base web in the non-linear pattern in the machine direction.

    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.

  • Patent number: 5099554
    Abstract: The invention relates to the production of non-woven fabrics in which an array of weft threads is created and then combined with a substrate, which may in itself comprise a set of warp threads. In the method according to the invention, the array of weft threads is formed by traversing a weft carrier which has a plurality of weft guides, across the weft-space between two sets of weft retainers (300), (302). At the end of each traverse, the weft carrier is jogged, (that is to say moved in the warpwise direction) so that at the next traverse, it lays a further set of weft yarns across the weftspace, and the weft yarns are hooked around the weft retainers.

  • Patent number: 5053098
    Abstract: In a method of an apparatus for the manufacture of a flexible reinforced polymeric article, such as a breaker fabric for a pneumatic tire, a layer of polymeric material is fed from feed means to a conveyor and a pair of laying head carriages are arranged to lay to and fro over said polymeric layer two reinforcing cords in an arrangement in which two successive transverse portions of one cord lie interdigitated between two successive transverse portions of the other cord in a manner whereby the two cords are free from overlapping cross-over regions.Means may be provided for applying a second layer of polymeric material whereby the cords are embedded between and consolidated in said polymeric layers.

  • Patent number: 5047109
    Abstract: Non-woven, bias laid fabrics, where the various fabric layers are held together by external means, such as stitching, and wherein, preferably, at least two of the layers are formed at an angle of from 30.degree. to 150.degree. relative to the long axis of the fabric, are formed by directing at least two pluralities of yarns back and forth across the width of the forming fabric, to be wrapped around or mounted on a series of needles formed on a moving conveyor, one conveyor being placed on either side and moving in the direction of the long axis of the fabric. Speed of movement of the yarns can be determined by the speed of movement of the mechanism for the machine operated to hold the various fabric layers together; preferably said machine mechanism moves more slowly near the ends of each cycle, so that yarn carriers are similarly slowed at either end of the forming fabric width, aiding in making successive courses of yarn lie parallel to each other without the necessity for extra equipment.

  • Patent number: 5002621
    Abstract: A method is used for producing reinforcing members preferably used in tires. The method comprises steps of causing cords to pass through a plurality of small apertures of a guide plate each for one of the cords to arrange these cords in a predetermined positional relation, winding the cords about winding type braking means, and extending the cords about a dancer roller. Thereafter, the cords are caused to pass through a plurality of small apertures of a movable guide plate each for one of the cords. The movable guide plate is reciprocatively moved in horizontal directions perpendicular to advancing directions of the cords so that the cords are reciprocatively moved onto a calender for rubber coating provided closely adjacent the movable guide plate to embrace the cords in the form of waves between rubber sheets and coat the cords by the rubber sheets, thereby obtaining the reinforcing member.

  • Patent number: 4933038
    Abstract: A method of forming an electric heater pad having a continuous resistance heater wire which zig-zags transversely back and forth in longitudinally spaced runs secured intermediate two insulating sheets, the method comprising: (a) laying the wire inbetween the sheets by successive passes back and forth transversely between the sheets, (b) drawing the two sheets with the wire therebetween between two first pressure rollers to bond central areas of the sheets together leaving border strips on each transverse slide edge of the sheets unbonded, and (c) subsequently, bonding the sheets together over the border strips, wherein each successive pass comprises: (1) catching the wire between the sheets in a nip between the first rollers near the juncture of the border strips and central areas at one side, (2) drawing the wire transversely across the sheets to beyond the side edges of the sheets at the other side where tension is applied to the wire forming it into a straight run extending transversely across the sheets

  • Patent number: 4883551
    Abstract: A plurality of strands is introduced by a reciprocating weft laying device into a layer of paste-like bonding material deposited on the upper surface of an endless belt. A plurality of warp strands extending in the warp direction is introduced into the paste over the first mentioned strands. A second plurality of strands in the weft direction is similarly introduced by means of a second reciprocating weft laying device and a second plurality of strands in the warp direction is introduced over these second weft strands. The paste-like bonding material is then cured by a heated roller to produce the finished material. Material may be made having only one set of warp strands and one set of weft strands or more than two sets each of warp and weft strands.

  • Patent number: 4867825
    Abstract: A stand-alone machine and a process for forming crosswise filaments for non-woven fabric comprises two sets of non-traversing edge spacing pins, each set with a gripper, and a traversing set of slider pins. The sets of pins are placed close together. Crosswise filament yarns are engaged by these sets of pins. The slider pins then traverse and pull the filaments to their full length. The crosswise filaments are cut and fixed to edge elements, which preferably may including adhering the crosswise filaments to selvage filaments. The edge elements are then separated to draw the crosswise filaments to their full width.
