  • Patent number: 4354301
    Abstract: There is disclosed a method for manufacturing a stripe-patterned metal plate or composite material. Plural kinds of metal sheet blanks having different colors are placed one upon another to provide a layer structure. The metal sheets of the layer structure are bonded to each other directly and metallurgically in a solid state to provide a layer-structured plate. The layer-structured plate is cut in a direction along a face extending at a predetermined angle to a layer face thereof to provide at least one thin metal plate intermediate. The metal plate intermediate is inserted into a complementary hole formed through a solid package of metal. Then, the package containing the metal plate intermediate is hot rolled into a predetermined length with its width remaining substantially unchanged so that the metal plate intermediate is simultaneously extended at a predetermined reduction rate with its width remaining substantially unchanged.
