  • Patent number: 5988253
    Abstract: A pocket coil spring structure assembling apparatus includes a feeder mechanism for supplying a group of pocket coil springs to a positioning transfer conveyor. A positioning transfer conveyor mechanism conveys the group of the pocket coil springs supplied from the feeder mechanism to a predetermined location. A cutter mechanism mounted between the feeder mechanism and the positioning transfer conveyor mechanism separates a group of the pocket coil springs from succeeding pocket coil springs by cutting to a given length. A press holding mechanism holds and lifts the group of the pocket coil springs on the positioning transfer conveyor by pressing the radial center of each pocket coil spring from opposite ends thereof. A press holding mechanism carrier mechanism moves the press holding mechanism in four, i.e. forward, backward, leftward, and rightward, directions. A spray mechanism including a spray nozzle applies a spray of an adhesive material to the group of the pocket coil springs.

  • Patent number: 5740597
    Abstract: A pocket coil spring producing apparatus includes a coil spring forming mechanism for forming coil springs, a hardening mechanism for hardening coil springs fed from the coil spring forming mechanism, a conveyor mechanism for cooling and conveying the hardened coil springs, and a compress inserting mechanism for compressing and inserting the coil springs conveyed by the conveyor mechanism into a two-fold sheet form of a sheet material. A sheet supplying mechanism folds the sheet material in two and feeds the same. A joining mechanism joins the two-fold form of the sheet material to have a row of substantially rectangular pouches into which are supplied respective of the compressed coil springs. A spring alignment mechanism aligns each compressed coil spring in a respective pouch in a lengthwise direction to return to a free, released state. A control mechanism controls the foregoing mechanisms.

  • Patent number: 5068148
    Abstract: A tool member includes a tungsten carbide based cemented carbide substrate and a diamond coating deposited on the substrate. The substrate has two diffraction peaks K.alpha..sub.1 and K.alpha..sub.2 indexed by index of pane (211) for tungsten carbide in X-ray diffraction. The peaks satisfy the relationship of 1.sub.1 /1.sub.2 .ltoreq.35, where 1.sub.1 and 1.sub.2 are heights of the peaks K.alpha..sub.1 and K.alpha..sub.2 measured from a base of a trough between the two diffraction peaks. For manufacturing the tool member, a green compact is first sintered to provide a tungsten carbide based cemented carbide substrate. Subsequently the substrate is ground and subsequently heat-treated at a temperature between 1000.degree. C. and 1600.degree. C. in a vacuum or in a non-oxidizing atmosphere. Thereafter, a diamond coating is formed on the substrate by vapor-deposition method.
