Method for manufacturing glass plate and manufacturing apparatus therefor

A method of manufacturing a glass sheet, the method comprising a conveying step of conveying a glass sheet by holding an upper part of the glass sheet in a vertical posture,

• the conveying step comprising:
• a first conveying step of conveying the glass sheet in a first direction along a direction perpendicular to a main surface of the glass sheet by a first conveying apparatus;
• a direction changing step of changing a conveying direction of the glass sheet from the first direction to a second direction, which is along a direction parallel to the main surface, at a direction changing position at a downstream end of a conveying path in the first direction;
• and
• a second conveying step of conveying the glass sheet in the second direction by a second conveying apparatus, wherein
• in the first conveying step, the glass sheet is supported by suspending the glass sheet by the first conveying apparatus, and
• in the direction changing step, a stopper is arranged at the direction changing position and the stopper is brought into contact with a lower part of the main surface of the glass sheet from a forward side in the conveying direction of the glass sheet conveyed in the first direction by the first conveying apparatus so as to prevent a lower part of the glass sheet from advancing toward the forward side in the conveying direction with respect to the upper part of the glass sheet.
