FEED ROLLER FOR GLASS, AND PRODUCTION METHOD OF PLATE GLASS

To suppress breakage of a feed roller for glass by reducing deflection of a connecting shaft, and a stress acting around the boundary between the connecting shaft and a support shaft.SOLUTION: In a feed roller 1 for glass including a roller part 2 in contact with a glass ribbon GR molded continuously, a support shaft 3 supported by bearings B1, B2, and a connecting shaft 4 for connecting both the roller part 2 and the support shaft 3, in which the connecting shaft 4 has a larger diameter than the support shaft 3, the support shaft 3 is provided with a first step part 5 for allowing a part near the connecting shaft 4 to have a relatively larger diameter than a distant part along the axial direction.SELECTED DRAWING: Figure 1 【課題】連結軸部の撓み及び連結軸部と支持軸部との境界周辺に作用する応力を低減して、ガラス用送りローラの破損を抑止する。【解決手段】連続的に成形されるガラスリボンＧＲに接触するローラ部２と、軸受Ｂ１、Ｂ２によって支持される支持軸部３と、ローラ部２及び支持軸部３の両者を連結する連結軸部４とを備え、支持軸部３よりも連結軸部４が大径とされたガラス用送りローラ１であって、支持軸部３に、軸方向に沿って前記連結軸部４に近い部位を遠い部位よりも相対的に大径にする第一段差部５を設ける。【選択図】図１
