New Hudson introduced the Metal Donut Roller in 1986 in response to the industrys interest in having only metal rollers in the annealing lehr. Several hundred Metal Donut Rollers are now operating successfully in float glass lines worldwide.
New Hudson was a pioneer in the development of Non-Asbestos covered lehr rollers back in 1979. Since then this Mineral Fiberboard has been chosen by glassmakers in more than (90) float lines globally. FF800 (MB800) Covered lehr rollers are very common in the flat glass industry typically used in B, C, D, and RET zones of the annealing lehr. The most frequently used material is Tenmats MB800 introduced back in 1981. This material designed as alternative to asbestos materials. Covered rollers are non-marking, have less of an affinity for sodium sulfate and dross deposits and provide excellent dimensional stability in the lehr. The primary disadvantage of covered rollers is the occurrence of embedded cullet and vulnerability to cullet damage.
New Hudson Corporation introduced the HTC™ High Temperature Composite Ringed Roller to the float glass industry in 1991. By the end of this year, over 2500 rollers will be operating successfully in (80) float lines worldwide. Today, the HTC™ Roller is the preferred option for the production of Ultra Thin and High Quality Automotive glass. The HTC™ roller eliminates embedded cullet, which can become embedded in the surface of a covered roller and also roll mark problems in the cold end of the lehr. The HTC™ roller is intended for use in lehr zones with circulating air.
