Hegla offers a neat trim

During lamination glass manufacturing, the PVB product often overlaps the glass edge which in turn causes quality issues during production. With a long-established history in glass machinery manufacturing, HEGLA has developed a fully automated, in-line, blade trimming system that provides greater accuracy and speed.

This HEGLA system is flexible and is particularly useful for architectural applications where multi PVB layers are used. Previously PVB overlapping problems could only be addressed by removing the excess by hand on LES sized glass - a time consuming job that is completely impractical when it comes to Jumbo applications.

The HEGLA PVB trimming system offers a simple, fully automated in-line operation that does not effect output and greatly improves positioning accuracy on the cutting table. The glass can be delivered by any automated loading system and trimmed in just one movement. 

Due to the front and leading edges of the glass being automatically trimmed of excess PVB, manufacturers gain considerable the benefits. This not only precisely brings the glass to the automatic positioning stops, but also the PVB removal improves the transportation of these two edges along the insulating glass line, as they rely on the flat bottom edge of the glass to remain on the vertical conveyors. 

For Jumbo cutting applications even a small inaccuracy at the positioning stops will be magnified greatly over a full sheet of glass. When manufacturing laminated insulating glass the greater the accuracy of cut the easier the assembly of the sealed unit.   

For over 35 years, the HEGLA group has worked diligently to provide the glass industry with technical solutions that provide real-time benefits. The unique fully automatic PVB trimming system has been carefully designed to provide a positive impact on production line efficiency through precision engineering.
