Method for manufacturing belt-shaped glass and device for manufacturing belt-shaped glass

A manufacturing method for a band-shaped glass, the manufacturing method comprising:

• a forming step of forming a band-shaped glass;
• an annealing step of performing an annealing treatment on the band-shaped glass;
• a cooling step of cooling the band-shaped glass having been subjected to the annealing treatment;
• a direction-changing step of changing a movement direction of the band-shaped glass having been cooled from a vertical direction or a direction forming a certain angle with respect to the vertical direction to a horizontal direction;
• and
• a horizontal conveying step of conveying the band-shaped glass having been changed in direction to the horizontal direction while supporting the band-shaped glass at a horizontal conveyance part,
• wherein the horizontal conveyance part is a floating belt conveyor having a belt, which causes at least a part of the band-shaped glass in a width direction to float from the belt by jetting air upward from a hole portion having at least one hole that is opened on the belt,
• wherein a tape is attached to a portion of the belt that is in contact with both of the sides of the band-shaped glass in the width direction of the band-shaped glass, and any holes in the portion of the belt that is in contact with both of the sides of the band-shaped glass in the width direction are closed by the tape,
• wherein, in the horizontal conveying step, the band-shaped glass is conveyed in the horizontal direction while a first propulsion for driving a conveyance in the horizontal direction is given to both sides of the band-shaped glass in a width direction of the band-shaped glass by the floating belt conveyor, and
• wherein a second propulsion for driving conveyance in the horizontal direction given to a center of the band-shaped glass in the width direction of the band-shaped glass is zero.
