  • Patent number: 11985762
    Abstract: A flexible laminated sheet manufacturing method includes thermocompression-bonding an insulation film formed of a liquid crystal polymer onto a metal foil between endless belts to form a flexible laminated sheet. The thermocompression bonding includes heating the flexible laminated sheet so that the maximum temperature of the sheet is in the range from a temperature that is 45° C. lower than the melting point of the liquid crystal polymer to a temperature that is 5° C. lower than the melting point. The thermocompression bonding also includes slowly cooling the flexible laminated sheet so that an exit temperature, which is a temperature of the sheet when transferred out of the endless belts, is in the range from a temperature that is 235° C. lower than the melting point of the liquid crystal polymer to a temperature that is 100° C. lower than the melting point.

  • Patent number: 5090456
    Abstract: A picking apparatus of a rapier loom has gripping bodies between a weft selection device and a yarn cutter. The gripping bodies are movable up and down. The gripping bodies selectively grip a plurality of weft yarns in accordance with a color pattern. One yarn cutter cuts the weft yarn gripped by the gripping bodies and severs the cut weft yarn from a woven cloth after the weft yarn is picked. Thus, neither catch cords nor an extra length of fringe nor a selvage cutter are needed.
