Magnat-Fairview Inc. in Chicopee, Mass., the result of the 2005 merger of Magnat Rolls in E. Hampton, Mass., and Fairview Machine in Chicopee, is believed to be the only designer and builder of custom heating, cooling, and calendering rolls in North America that also designs and builds the roll stand. That allows MF to simulate, design, and build an entire system for tighter heat transfer and gauge tolerance, like the calender (photo) for a high-temperature, ultra-thin film, which reportedly holds gauge tolerance of 0.00005 in. MF designs and builds custom rolls and stands with a roll-bending deflection compensation system for film applications like electric-motor windings and membranes for fuel cells and rechargeable batteries. Heat-transfer rolls with double walls, spiral or laterally fluted channels, and one or two variable flow paths, reportedly can maintain ±1° F over the entire roll face.
