Erdman’s Vertical Insulating Glass Parallel Process Line derives its name from the innovation of shuttling the topping lite to a back lane. Therefore, the two glass lites run parallel to each other, leading to a significant increase in speed. Compared to traditional IG processes, the line is more ergonomic and has less wasted motion by the operator. There are no manual touches to glass after washer and no close contact between operators. It requires three to four operators, versus seven to nine on a traditional line. The line also includes auto placement of spacer location, and argon is filled and finished on the line.
