  • Method for manufacturing glass panel unit, method for manufacturing glass window, and device for manufacturing glass substrate with spacer
    Patent number: 10464845
    Abstract: A first glass substrate, a die including a penetrating space, a seat member, and a punching member are set so as to be arranged in this order. Subsequently, the seat member is punched by the punching member to remove part from the seat member through the penetrating space of the die. The part removed, is placed on the first glass substrate by the punching member so as to allow the part to serve as at least one spacer. Thereafter, the second glass substrate is placed on the first glass substrate with the at least one spacer in-between to form a glass panel unit.

  • MANUFACTURING METHOD FOR GLASS PANEL UNIT AND MANUFACTURING METHOD FOR GLASS WINDOW
    Publication number: 20180038152
    Abstract: A first glass substrate and a second glass substrate which are placed to face each other with a seal member in-between are bonded to each other with the seal member. Subsequently, the first glass substrate, the seal member, and the second glass substrate are cut collectively along a cut plane passing through the seal member from one of the first glass substrate and the second glass substrate bonded to each other. Thereby, a glass panel unit is manufactured.
