    Abstract: A radiator hose is provided with an inner tube rubber and a cover rubber. The inner tube rubber is coiled on the outer circumference with filament yarns made of nylon 6,6 separating predetermined spaces each other. The filament yarns are twisted at predetermined twist number before coiling, and pass through an adhesive agent supplying step, a dry-heating step while applying tension to the filament yarns and reel-hank steps, and goes into a wet-heating step. For the wet-heating step, the filament yarns are given temperature equivalent to a vulcanizing temperature, applying no tension to the filament yarns. By the wet- and dry-heating, the filament yarns are prevented from biting into the inner tube rubber. Since the filament yarns are immersed into the solution of an adhesive agent before the dry-heating, the solution attached on the filament yarns is dried off rapidly by the dry-heating thereafter.

  • Patent number: 5834056
    Abstract: The invention relates to a fibre bundle impregnating process, in which the fibre bundle is placed on a support and the support, together with the fibre bundle thereon, is moved past an impregnating device. In this process the fibre bundle is supported during the impregnation process and consequently a fibre-reinforced plastic is produced, fibre breaks being largely avoided during its production. One of the possible variants of the inventive concept comprises an impregnating wheel, which receives the fibre bundle and leads it past an impregnating device.

  • Patent number: 5780099
    Abstract: A process for manufacturing a continuous dental floss brush comprising alternating portions of thread sections which do not stretch significantly under tension and brush sections which stretch under slight tension, includes the step of coating at least the thread sections of a reverse twisted high tenacity nylon yarn with a solution of polymer in a volatile solvent, the polymer being selected from the group consisting of nylon, polyurethane and mixtures thereof. The thread sections of the yarn are thereafter heated to vaporize solvent therefrom while the yarn is maintained under a tension of from 0.15 to 1N. In the humidifier assembly, having a housing which defines a humidifier zone, the brush sections of the yarn are exposed to a mixture of steam and gas, the steam and gas mixture having a temperature of from 130.degree. C.

  • Patent number: 5672375
    Abstract: A method and apparatus for tipping, cutting, and sorting sutures includes a suture supply, a tipping station wherein delimited portions of the suture are tipped, preferably with a cyanoacrylate tipping agent, a diameter measuring station, a cutting station wherein a knife is operated to cut the suture at a tipped portion to form cut suture lengths having tipped suture ends for insertion into the barrel end aperture of a surgical needle, and a pair of graspers for alternatively grasping and drawing the suture from the suture supply through the tipping apparatus, the diameter measuring station and the cutting station. Optionally, a drying station can be interposed to hasten the curing of the tipping agent. Preferably, a controller is provided for controlling the sequence of operation of the apparatus and for controlling sorting of cut suture lengths deposited by the graspers onto a tilting sorting table.

  • Patent number: 5643628
    Abstract: A process for tipping surgical sutures includes dispensing tipping agent one drop at a time and contacting the suture portion to be tipped with the drop of tipping agent. A transversely oriented lifting/wiping string may be used to lift the suture into contact with the drop and may wipe away excess tipping agent. Alternatively, a transversely oriented string may be used to catch a drop and then place the drop onto the suture. The tipping agent absorbed into the tipped portion can then be cured and cut to provide a tipped suture. The tipping process and apparatus can be used in conjunction with a needle-suture assembly process. The process advantageously controls application of a droplet of tipping agent to minimize the amount of tipping agent used, thereby providing an aesthetic needle-suture attachment. Apparatus are disclosed for performing the process.

  • Patent number: 5527410
    Abstract: A method and an apparatus for winding a cord continuously. A rotation of a winding bobbin around which a cord to be a tension member of a belt and so on is wound is detected directly or indirectly. A cord is forwarded in an axial direction of a winding bobbin at a pitch, which corresponds to a diameter of the cord, in relation to a rotation of a winding bobbin. And a bobbin axis of the winding bobbin is rotated at a constant speed by rotation driving means so that the cord is wound around the winding bobbin. The rotation of the bobbin axis is detected by rotation detection means directly or indirectly. The cord is forwarded in the axial direction of the winding bobbin in relation to the rotation of the winding bobbin at a pitch which corresponds to the diameter of the cord by receiving signals from the rotation detection means.

  • Patent number: 5376412
    Abstract: The process for manufacturing strings according to the invention is of the type comprising a step in which a thread is produced from fibres, a step in which the thread is impregnated with a resin, a step in which the impregnated thread is coated with a synthetic material to provide it with a sheath, a step in which the synthetic material is caused to be completely cross-linked, and a step in which the thickness of the sheath is adjusted. It is characterized by use of discontinuous fibres that are subjected to textile operations of intersecting and drawing-twisting. The process according to the invention makes it possible to produce strings designed to be subjected to tensile stress, in particular strings for rackets and musical instruments.
