Abstract: 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.

Abstract: The present invention describes a roll for use in glass manufacture, especially non-dusting TFT glass. The roll may include a hollow fused silica cylinder. 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 roll may be reinforced with an internal metal rod that is secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion.

Abstract: A refractory roll cover is described that reduces the amount of noxious dust during the production of glass sheet. The roll cover comprises a plurality of segments, including low dusting millboard segments mechanically supported by highly rigidized compressed fiber segments. The millboard segments are adapted to contact the glass sheet. The millboard is chosen so that any dust produced has little affinity for the glass sheet or is not easily fluidized by convective currents. The highly rigidized compressed fiber has a fused surface that releases little dust. The resultant roll cover substantially eliminates dusting while providing a mechanically superior roll cover.
