An apparatus and method for manufacturing glass include a heat extractor configured to extract heat from molten glass. The heat extractor includes a first conduit and at least one second conduit which may include a plurality of second conduits circumferentially surrounding the first conduit. The first conduit and the at least one second conduit are configured to flow a fluid therethrough.

A hot glass sheet processing system includes a roller conveyor (22) having sintered bonded fused silica rollers (24) and a roller support structure (34) located within a heated location (32) together with an elongated cooling unit (36) having a housing (38) defining a cooling chamber (40) that receives and has bearings (42) that rotatably support an aligned set of roller ends (30) having end caps (86) adhesively bonded to the roller ends. The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).

Device for manipulating the edge of a ribbon of glass comprising a wheel, and float glass installation comprising such a device. A device for manipulating the edge of a ribbon of pasty glass travelling on a bath of liquid in a float chamber, comprising a wheel (1) positioned at a distal end of a barrel (2), the wheel (1) being turned about its own axis, this axis being concurrent with the longitudinal geometric axis of the barrel and making therewith a permanent fix angle determined by design, the barrel (2) having a possibility for adjustment in rotation about its longitudinal axis, and installation comprising such a device.

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).

A roll for use in glass manufacture, such as in the production of non-dusting TFT glass, includes a hollow silica cylinder. A rod extends through the interior of the silica cylinder. A cooling volume is contained within the cylinder and extends around the rod. End caps are mechanically fixed to the roll. Pulling flats are fixed in place by inner and outer end plates. A compression fitting secures at least the outer end plate to the roll. The rod may serve to reinforce the roll and may be secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion.
