New Hudson introduced the Metal Donut Roller in 1986 in response to the industry’s 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 Corporation began manufacturing Stainless Steel Lehr Rollers over 52 years ago. Since that time NHC has produced thousands for over (215) float lines worldwide, using our expertise in Design, Engineering and “Know How”.
Stainless Rollers are typically made in 305, 216 and 203mm diameters and in 25/20, 25/12, 18/8 and 25/4 Chrome/Nickel alloys.
New Hudson introduced the Freedom Coat™ Roller back in 1997 as a solution for Sodium Sulfate and Tin Oxide build-up occurring on the surface of Stainless Steel Rollers. Today, the Freedom Coat Plus™ Roller is the preferred option for Ultra Thin and High Quality Automotive glass production. The result is an extremely smooth and hard polished roller surface. A surface that can be easily and effectively cleaned either in the plant without special equipment or in the lehr at operating temperature. The hard ceramic surface can withstand aggressive cleaning methods without damaging the roller surface. Additionally, the thermal barrier characteristics of the various ceramic coating options reduce heat transfer between the glass and the lehr roller. And no, the ceramic coating will not spall off due to thermal shock. Please contact us to discuss how Freedom Coat™ might benefit your float glass operation.
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.
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.
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 Tenmat’s 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.
