New generation of conveying technology

"The most important thing for us has always been to transport glass gently and safely through the cutting and stacking processes in order to help you achieve the maximum yields. We have taken a big step into the future with our next generation of conveyors."

Markus Schmid, Senior Manager Mechanical Concept Engineering at Grenzebach Maschinenbau GmbH


Conveying technology: even more dynamic, even more robust


With a new generation of conveyor technology Grenzebach makes it possible to further increase the availability of float glass plants. Transporting glass gently, carefully and safely has always been one of Grenzebach's top priorities. The specially developed drive train without cardan shafts represents a major step forward. The number of components in the drive has been significantly reduced - cardan shafts and belts are a thing of the past. This now results in even greater dynamics, less maintenance work and a lower spare parts inventory. The new drive train also offers the possibility of connecting all engines directly, which ensures smoother running and higher positioning accuracy. Gentle glass transport all along the line! Thanks to its new design, compact construction and transparent covers, the new conveyor technology generation also provides a clear view of key components and fast access for maintenance work. Of course, existing systems can be equipped with the new conveyor technology so that everyone can benefit from the advantages.



CNUD EFCO GFT & Grenzebach: From Hot to Cold - Integrated Solutions for Flat Glass Manufacturers


Markus Gruber
Tuesday, October 20
from 1.40 - 2.10 pm

Hot to cold, the joint mission of Grenzebach and CNUD EFCO GFT. From the tin bath to the annealing lehr and the cold end, from coating to transporting the final product to the warehouse – all from one single source. How will you benefit from this? Find out in our webinar "CNUD EFCO GFT & Grenzebach: From Hot to Cold – Integrated Solutions for Flat Glass Manufacturers" with Markus Gruber, Vice President Sales Business Unit Glass on October 20, 2020 at 1.40 pm.


Collaboration App: Next Level Service Support


Florian Nagler
Wednesday, October 21
from 1.40 - 2.10 pm

Florian Nagler, Head of Global Service Sales at Grenzebach, will show how the Collaboration App makes remote support even more powerful. In a production environment managed by SERICY, cross-company collaboration is possible at any time. Maintenance staff and production planners can plan maintenance together; tasks can be distributed and photos and videos can be shared via the integrated chat. "Via a live video stream, our service specialists can provide customers with concrete support and instructions for work on the system - bringing us as a partner much closer again". Florian Nagler emphasizes: "Being close to our customers throughout the entire life cycle of a production line is an important core of our corporate and service philosophy. Wherever the individual participants are located. The Collaboration App is another important step forward - crisis-proof even against events like the COVID 19 pandemic. Through the app, we and our customers can share our wealth of experience with one another."


Coating Technology: Increases the value of the glass


Dr. Jens Ellrich
Thursday, October 22
from 10 to 10.30 am

Healthy indoor climate, ideal lighting conditions and energy efficiency of residential and office complexes. Coated glass has a lot to contribute to this. Glass is becoming increasingly important as a construction element - after all, we spend 80 percent of our time in buildings. And as urbanization continues, coated glass can play a key role in energy-efficient and intelligent buildings and mobility. Further improving product properties and setting new trends with innovations - this is what drives manufacturers of architectural glass; and Grenzebach supports with technology tailored to individual requirements. The spectrum ranges from fully automatic PVD coating systems for glass panes up to 3.4 meters wide, to which all relevant layers for high-end products can be applied. The coating processes are optimized and layer structures are developed in our own laboratory coater.

Digitalization of Glass Production - Added value for all users

Peter Seidl & Maximilian Ocker
October 22
from 12 to 12.30 pm


A huge amount of data is generated in the various stages of the glass value chain. Securing, integrating and analyzing this data and generating added value from it is a central task for a sustainable glass industry. With the SERICY platform, Grenzebach has created a platform for a correspondingly efficient ecosystem. By providing glass products with information on the traceability of the production process, for example, their value can be increased. This is just one example. The benchmark for digital solutions must be that actual added value is created - higher quality, more output and/or reduced use of resources. In the presentation in the digital conference area at Messe Dusseldorf, both Grenzebach experts will show how digital solutions create added value for users throughout the value network. In order to enable digital added value, a transformation of the sales and development process in the glass and mechanical engineering industry is necessary to implement concrete use cases.

“Climate protection and energy efficiency are huge issues for the glass industry and gaining momentum due to legislation and companies’ own targets. Waste heat recovery can be implemented today, even if the whole plant is operated with hydrogen in the future. We’re developing agile solutions for the real world each and every day.”

Dennis Schattauer, Managing Director at German Floatglass Technology GmbH


Waste Heat Recovery


Energy efficiency is a topic that Grenzebach and CNUD EFCO GFT are jointly focusing on intensively. With a Waste Heat Recovery (WHR) system, there is already a concrete solution that meets the major challenges facing the glass industry: achieving climate targets, resource conservation and cost efficiency. As one of the few solutions available on the market, the WHR system from CNUD EFCO GFT achieves all three goals in harmony. In flat glass production process, the starting point is the relatively inefficient glass melting process with a relatively low energy efficiency. A large part of the energy loss is contained in the waste gas from the glass melting tanks. "Our WHR system uses the waste heat from glass melting plants to generate electrical energy and heat and cooling energy for process and air conditioning purposes - and does so with considerable efficiency," says Dennis Schattauer, Managing Director of GFT GmbH. The effect: a significant increase in energy efficiency, improved climate balance because CO2 emissions are avoided, considerable cost savings because less electricity and fossil fuels have to be purchased.
