- Cutting Technology
Grenzebach’s cutting and breaking technology transforms the continuous glass ribbon into the format required. It allows you to cut glass to size with very minimal product loss.
Cutting technology lies at the heart of the cold end of a float glass production line. Combined with the breaking system, the cutting heads, force-regulated controls and an intelligent optimization system form a superbly efficient unit.
Longitudinal and cross cutters with force-controlled cutting heads, which are adapted to handle thin, regular or thick glass, score the glass. Cutting pressure is applied precisely based on glass thickness and stress in the glass and by using closed-loop control.
The multi-longitudinal and cross cutters can make various formats, even with very small sheets of glass. By changing dynamically to different cutting bridges, formats are produced continuously without any interruptions.
We have a broad portfolio of solutions for cross, center or lengthwise breaks so that the edges are the best possible quality.
Defects in the glass ribbon, such as inclusions, bubbles or stones, force glass manufacturers to dispose of the cullet (waste glass) in a cullet bin. Depending on the roller pitch, the shortest cullet plate was 500 mm or 19 11/16 inches long. Thanks to Grenzebach’s short cullet plate system, this figure can be cut to 170 mm or 6 11/16 inches. This is possible because the cullet is disposed of directly after the break roller.
Combined with our digital float scan edge camera and look ahead cutting optimization system, we can offer function-rich cutting technology. All in the interests of superior precision, quality and yield.
The float scan edge system extends over the complete width of the glass ribbon - and detects with two single cameras constantly providing useful information:
FSE-d can be directly integrated into the digital system by means of the SERICY. The IIoT platform developed in-house and the supplied information are directly useful for product optimization and reporting. FSE-d provides more accurate function of the cutting technology, which is the core of the cold end of the float glass production line with numerous added values: higher yield, higher quality, easier processes, further networking and more data safety.
Our high-performance solution can plan production, manage orders and guarantee that all processes are ones that are efficient and can be counted on.
Construction and commissioning of a new glass production line is only the first stage in a good customer relationship. Professional service in daily operation is just as important: We want your investment to be profitable without any interruption – that’s why our engineers are there for you with guidance and support over the entire life cycle of the plant.
