AGNORA has installed a new double-edger machine that officials claim to be one of North America’s largest. AGNORA’s marketing manager, Adam Mitchell, says the machine can process up to 3,000 mm by 4,600 mm of glass at 19 mm thick. In comparison, the world’s largest double-edger at the time, sold to Saint-Gobain in 1996, could process glass sheets sized 2,200 mm by 4,800 mm at 20 mm thick, weighing 1,433 pounds. C.M.B. Costruzioni Meccaniche Besana S.r.l. provided that machine.
AGNORA is known for its massive insulating glass units (IGU). In fact, it recently fabricated one of its largest IGUs, measuring 100 inches by 299 inches, for Steelworks. The company can fabricate, polish, edge, laminate, insulate, heat and digitally print glass up to 130 inches by 300 inches.
The company’s new double-edger, supplied by Intermac, enables the company to increase capacity for several volume units and offers better precision and speed since workers don’t have to handle the glass multiple times. Mitchell says AGNORA purchased the equipment to optimize efficiency at the Collingwood, Ontario, plant.
“The double edger allows us to better prep edges for tempering or final polishing without manipulating the glass several times,” he says. “It also frees time on other equipment, allowing for more capacity to be reached.”
Mitchell explains that double-edgers allow for edge sealing for heat-treated products. This includes products that require polish that are typically exposed edge glass structures, such as stairway stringers, treads, balustrades, bridges and fins.
Installing the new double-edger is just one step among others that AGNORA has taken to optimize production. The company recently custom-designed its own seaming line inspection station. Officials say the new seaming line design, one of the first stops in the company’s quality control process, limits background visual clutter. Officials explain that the station’s lighting is angled against a neutral background so that light does not shine directly at the operator and provides a higher contrast to see glass imperfections.
