Hegla has introduced the ProLam LSR laminated glass cutting system, which it says achieves 20% more throughput, without the requirement for additional operators.

While heating and separating are traditionally the most time-consuming processes during the cutting of laminate glass, Hegla adds that these can be significantly accelerated with the new laser technology in the ProLam LSR.

Following the cutting process, the surrounding glass remains cold, thus preventing subsequent delamination.

“The thicker the film and therefore the overall composite, the more time is saved,” explained Hegla’s managing director, Bernhard Hötger.

“We can cut a 10-layer film in 10 seconds and maintain the maximum quality of the composite edge, thanks to the gentle use of the laser.”

The laser diode heater is positioned above the glass, protecting it from dust, lucite, oil and glass splinters. The performance of laser diodes can also be maintained for a longer time compared to infrared radiators, according to Hegla.

An additional benefit of lasers is the localised heat input: the glass only gets warm to the touch so that subsequent cuts can be made without any cooling time.

In combination with another existing or new cutting system, the output can also be significantly increased. “The combination of smart cutting distribution, glass-friendly laser technology and just one operator achieves a throughput that meets the highest demands,” explained Bernhard.

Compared to conventional heating technology, LSR technology is also said to reduce energy consumption. The laser diode is only switched on briefly and, depending on the cutting length, is activated partially or fully.
