The present invention relates to a water-cooled handling roll (100) for handling a load (50), in particular a thin slab, in a furnace for temperature heating, maintaining and for buffering, arranged between casting and roughing, in a continuous casting and rolling process for thin carbon steel slabs. The roll (100) comprises a first internally hollow shaft (110), which is coated by an insulating and/or refractory material and a plurality of wheels (25) connected in stably fixed manner to an outermost surface (111) of the first shaft (110) to handle and support the load (50). According to the invention, the roll (100) also comprises a second shaft (120) arranged within an inner cavity of the first shaft (110) in position coaxial to the first shaft (110) and so as to define a gap (30) between the first shaft (110) and said second shaft (120). The roll (100) further comprises cooling water circulation means housed at least in part within said second shaft (120).

In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The spring elements project outward from the annular hub such that an end of each spring element is positioned radially outward from a base of each spring element and is circumferentially offset relative to the base of each spring element.

A glass sheet bending method for glass sheet bending utilizes a primary actuating mechanism (154) for moving lower and upper mold support linkages (26, 48) from a flat shape to a curved shape of a constant radius provided by connection links (28) and control links (34) of the linkages. The lower and upper linkages (26, 48) having one pair of connector links (28) with control links (34) configured to allow a secondary actuating mechanism (155) to provide linkage movement on one lateral side thereof independently of on their other lateral side.

A substrate transmission apparatus is provided. The substrate transmission apparatus includes two supporting stands, a transmission shaft having two end portions, a supporting shaft having two end portions, first rollers, and second rollers. Two end portions of the transmission shaft are respectively connected to the two supporting stands. Two end portions of the supporting shaft are respectively connected to the two supporting stands, and the supporting shaft is located above the transmission shaft. The first rollers are fixed at intervals on the transmission shaft and rotate with the transmission shaft to convey a substrate placed thereon. The second rollers are rotatably connected to the supporting shaft and are in contact with an upper surface of the substrate, such that the substrate is conveyed and sandwiched between the first rollers and the second rollers.

Pulling rolls (13) for glass ribbons (11) and methods for manufacturing such rolls are provided. The rolls include a shaft (17), a plurality of heat-resistant discs (15) mounted on the shaft in face-to-face contact, and a pair of fittings (25 or 25,31) affixed to the shaft which apply an axial compressive force to the discs. The magnitude of the axial compressive force is adjusted so that the portions (27) of the roll surface (33) which contact the glass ribbon during use have a Shore D hardness at room temperature of between 30 and 55. The rolls achieve a long service life without applying excessive force to the glass ribbon or generating high levels of particulate contamination.

This invention relates to forming a complex shape glass (10) by bending a horizontal sheet glass (21) in a longitudinal direction and a cross direction. As a heated sheet glass pinched by multiple straight rollers (30, 30) consisting of upper-lower pairs disposed on a curved conveying path is carried in a downstream direction the sheet glass is bent along the curved conveying path. In a next step, the sheet glass curved in the conveying direction is bent in the conveying direction and in a direction perpendicular to the conveying direction by a convex forming roller with its center bulging in a curve (33, 35, 83) and a concave forming roller with its center waisted in a curve (34, 36, 82), and a complex shape glass is obtained.

A heat-resistant pipe is arranged so as to traverse below a glass ribbon in a float bath of molten tin, and bubbles emanate from the heat-resistant pipe, thereby making the bottom surface (which is in contact with the tin) uneven. Alternatively, the bottom surface is made uneven with a roller for lifting the glass ribbon out of the float bath into an annealing furnace. In addition to these operations for making the glass surface uneven, a film can be applied to the top face of the glass ribbon (i.e. the surface that is not in contact with the tin) by CVD, supplying a mixed gas of raw material from coaters. Thus, the invention makes it possible to manufacture a glass sheet having an uneven surface efficiently, using a technique for processing the surface of a glass sheet that is suitable for a production line for float glass.

A glass sheet 18 is heated to a forming temperature in a heating furnace 16, the heated glass sheet is conveyed along a conveying plane defined by a plurality of rollers of a roller conveyer 13, and is moved up and down on the rollers 12A to 12M according to the position of the glass sheet 18 to curve a part of the conveying plane with respect to the glass sheet conveying direction to bend the glass sheet 18 to have a desired curvature by its own weight. The rollers 12A to 12M are curved rollers.
