Abstract
A method for producing a glass article includes a forming step (P1) of forming a glass ribbon (2) from a molten glass (6) and a transport step (P2) of transporting the glass ribbon (2) along a transport path. In the transport step (P2), a first roller (9a) and a second roller (9b) configured to transport the glass ribbon (2) while in contact with a first end portion (2s) and a second end portion (2t) of the glass ribbon (2) in the width direction, respectively, are disposed, and a speed difference is provided between the first roller (9a) and the second roller (9b).
Claims9
A method for producing a glass article, the method comprising:
- a forming step of forming a glass ribbon from a molten glass;
- and
- a transport step of transporting the glass ribbon along a transport path, wherein
- in the transport step, a first roller and a second roller are disposed for the glass ribbon at a temperature within a temperature range of 300° C. or higher and configured to transport the glass ribbon while in contact with a first end portion and a second end portion of the glass ribbon in a width direction, respectively, and a speed difference is provided between the first roller and the second roller.
A method for producing a glass article, the method comprising:
- a forming step of forming a glass ribbon by using a down-draw method;
- a vertical transport step of vertically transporting the glass ribbon;
- a transport direction changing step of changing a transport direction of the glass ribbon from a vertical direction to a horizontal direction, by transporting, along a curved transport track, the glass ribbon after being subjected to the vertical transport step;
- and
- a horizontal transport step of horizontally transporting the glass ribbon after being subjected to the changing of the transport direction, wherein
- in the vertical transport step, a first roller and a second roller configured to transport the glass ribbon while in contact with a first end portion and a second end portion of the glass ribbon in a width direction, respectively, are disposed and a speed difference is provided between the first roller and the second roller.
