    • PROBLEM TO BE SOLVED: To suppress the occurrence of devitrification or striae by cooling the surface of molten glass in the time point of forming the molten glass.
      SOLUTION: The glass manufacturing apparatus is provided with a flow-out pipe for allowing the molten glass to continuously flow out, a molding die for continuously forming the molten glass flowing out from the flow-out pipe to be plate-like in the glass drawing direction and a cooling body for cooling the molten glass continuously formed in the molding die. The cooling body is installed over the molding die. The occurrence of the devitrification or the striae is suppressed by bringing the cooling body into contact with the molten glass to control the surface temperature so that the viscosity logη of the molten glass becomes 2-8.

    • PROBLEM TO BE SOLVED: To provide a method for continuously forming glass having uniform heat history while continuously allowing molten glass to flow down into a forming mold; and an apparatus used therefor.
      SOLUTION: In the method for continuously forming glass by pouring molten glass into one end part of a forming mold 20 having a predetermined product width while allowing the molten glass to continuously flow down and by drawing the glass out of the other end, at least a part of the glass in the glass drawing direction is formed while being subjected to heat exchange. The heat exchange is performed in a portion at least except the near end portion of a bottom plate part 21 of the forming mold 20, thus cooling the glass base. The forming mold 20 of the glass forming apparatus 1 has the bottom plate 21, and a heat exchange unit 24 is arranged in at least a part of the glass drawing direction of the bottom plate 21.

    • PURPOSE: To manufacture a glass block causing no distortion of an image, by premolding molten glass to the shape of a strip in a shoot whose width is almost equal to the inside width of a mold, feeding the premolded glass to the mold, and horizontally moving the mold in synchronism with the feeding speed while suitably lowering the mold.
      CONSTITUTION: A gate 12 attached to the feeder 11 of a melting furnace 10 is opened to lead molten glass G to a mold 20 through a shoot 30. The shoot 30 has a rectangular cross-sectional shape, and the width is almost equal to the inside width of the mold 20, so the glass G is premolded into strip glass G' whose width is almost equal to the inside width of the mold 20. The mold 20 is horizontally moved in synchronism with the feeding speed of the glass G' through a horizontally moving table 23 mounted on a vertically moving table 40 to charge the glass G corresponding to one layer into the mold 20 from one end to the other end. When a switch 58 contacts with a stopper 57, the moving direction of the mold 20 is reversed, and the glass G' for the next layer is charged. During this time, by working the table 40, the mold 20 is lowered so as to keep the height of the shoot 30 to the glass surface constant.
