A support apparatus can comprise a cylindrical rod extending along a first rotation axis and comprising a first end portion provided with a first convex spherical segment and a second end portion provided with a second convex spherical segment. A first area can be configured to receive a portion of the first convex spherical segment. A second area can be configured to receive a portion of the second convex spherical segment. The cylindrical rod can be pivotable about a first pivot axis perpendicular to the first rotation axis. In some embodiments, methods of supporting an object can comprise engaging a surface of the object with the outer surface of the cylindrical rod wherein the first cylindrical rod supports a weight of the object while the first cylindrical rod is supported by the first fluid cushion and the second fluid cushion.

In a manufacturing method of a glass roll, a transport device transports a glass film coupled to lead films via coupling portions. The transport device separates the lead films and/or the coupling portions from a heating roller when the lead films and/or the coupling portions pass by the heating roller.

Disclosed is a clamping device at an edge of a substrate glass during molding based on an overflow technique and an operation method thereof. The clamping device comprises a primary clamping unit and a secondary edge drawing unit that are clamped on edges of two sides of a glass plate, respectively. The primary clamping unit is arranged above the secondary edge drawing unit and is closer to a guide plate than the secondary edge drawing unit. The operation method comprises during the molding of the glass plate, enabling clamping wheels of the primary clamping unit and wheels for cooling and edge drawing of the secondary edge drawing unit to clamp the edges of the two sides of the glass plate to make liquid glass at the edges merge and bond together to obtain a bonded glass plate; and introducing cooling air to cool edges of the bonded glass plate.
