ガラスロールの製造方法
Document Type and Number:
Japanese Patent JP7148837
Kind Code:
B2
Abstract:
A method of manufacturing a glass roll includes separating unnecessary portions from a glass ribbon by cutting the glass ribbon along a longitudinal direction while conveying the glass ribbon. The method also includes passing the glass ribbon, from which the unnecessary portions are separated, through a looseness conveyance region on a conveyance path where the glass ribbon is loosened, and taking up the glass ribbon around a roll core at a downstream end of the conveyance path. A suction conveyor is provided between the looseness conveyance region and the downstream end on the conveyance path. While the glass ribbon is conveyed by the suction conveyor, the glass ribbon is tensioned between the suction conveyor and the downstream end on the conveyance path along with taking up the glass ribbon around the roll core.
