In 2008 Vesuvius, a producer of fused silica glass tempering rolls used in the production of flat and curved safety glass, pioneered the all-mechanical endcap, using no glue or resins to connect the ceramic to the endcaps. This product, known as Smartly Driven™ endcaps, was designed to withstand the high temperatures needed to produce tempered, low-E glass. The glue was always the weakest point, and failure would cause significant downtime for machinery operators when it failed, according to the company.
Vesuvius’ latest innovation is called Smartly Driven™ Plus Rolls. The new design of glass tempering roll brings greater accuracy, tighter tolerances, is much stronger and somewhat lighter than the existing designs, according to the company.
