INNOVATIONS AT GLASSTEC

A diamond cutting head that reduces micro-cracks to a minimum,

new systems to measure – among other things – the tension of thin

glass, and a machine concept for tempering of bottles. According to

the German Engineering Federation (VDMA), those are just some of the

highlights with which Germany’s glass machine manufacturers will be

showing their innovative strength at the industry’s leading trade show

glasstec in Düsseldorf from 21 to 24 October.

Every penny counts when a company makes bottles, particularly for the beverage industry. The thinner the bottle, the less material is used, and the lower the expenses. Moreover, the breaking resistance needs to be the same or – preferably – high-er. German company JSJ Jodeit, which supplies glass melting fur-naces and special glass machin-ery, has now developed a concept for a thermal tempering unit that

can be integrated into existing bottle production lines. Its main feature is that it will be installed directly after the IS-machine, at a point where the bottles are still hot, as they have only just left the machine. This means that to reach the temperature required for tempering purposes, much of the heating process can be omit-ted. This, of course, saves energy, while also being more eco-friendly.

The hot bottles are fed from the IS machine into a unit where they are first heated up to the needed temperature for thermal temper-ing. At this stage they are also homogenised. The second step in the process involves the sud-den and abrupt cooling of the bottles. The tempered bottles are then transported to the existing annealing lehr where they undergo further cooling. According to the owner of JSJ Jodeit, Harald Jodeit, Ph.D., there are plans to realise the concept as a pilot plant in close collaboration with an IS machine and container glass manufacturer.

CONSTANT PRESSURE AT ALL TIMES

Another highlight will be offered by German glass machine manu-facturer Grenzebach. This com-pany has developed a new cutting head, designed specially for thin glass and minimising the number of micro-cracks that may occur during the cutting process. The benefit is achieved through special controls which keep the pressure of the cutting tool on the glass at a constant level at all times. “More features in less space,” says Roland

Jennings, Head of Development at Grenzebach. This is appar-ently all that needs to be said. However, he adds that the new cutting head will be compatible with current tools, so that it can be retrofitted into existing machinery.

But Grenzebach also has a lot to offer in matters of measure-ment engineering. Since the inte-gration of Dr. Schwab Inspection Technology GmbH, a company specialising in image process-ing and surface inspections, Grenzebach has been marketing a range of measuring machines for surface tension, glass thick-ness and defect analysis. Franz Krommer, Sales Manager at Dr. Schwab, says: “We have, among other things, a system that permits reliable and usable tension measurement for sheet glass,” an innovation which he describes as “hitherto unparal-leled”. Several units are already in use, and the response has appar-ently been consistently positive. They will be presented at glasstec.

A GLOBALLY UNIQUE SELLING POINT

Another company worth visit-ing will be Bystronic glass. Its new product, called speed’line, can produce triple-glazing in the same amount of time taken by con-ventional lines for double-glazing. Bystronic will also be presenting a new technique that allows the filling of both spaces between panes with inert gas at the same time. “This,” says Product Manager Tobias Neff: “gives us a globally unique selling point in the industry.”

Symposium on quality, monitoring- and process control

On 22 October the German Engineering Federation (VDMA) e.V. will be inviting experts to a high-calibre symposium boa-sting 10 top-notch speakers. This will form part of the “glass technology live” special show during glasstec. Featured on the agenda are themes such as quality control, monitoring and process control.

The morning session will be hosted by Dr. Helmut Weinläder from the Bavarian Centre for Applied Energy Research (ZAE). The series of lectures will be opened by Rainer Feuster from Viprotron GmbH, who will speak about the various possibilities of scanner-based inspection during IGU production. Klaus Puschmann of Bystronic glass will then explain how automation can avoid defects in IGU production

as well as solutions for inline quality assurance and process control, are the topics covered in the lecture by Dr. Helmut Weinläder from ZAE. He will present the latest research results and technologies.

Ulrich Bauereiß from Dr. Schenk GmbH will explain how a single intelligent inspection system can detect both smaller local defects such as inclusions, impurities or glass breakage

glass production. The morning session will close with a lecture by Jens Kayser from Isra Vision on the topic of ‘Inline inspec-tion for every process step within the automotive glazing pro-duction as clear competitive edge’.

After lunch, Andreas Mader from Lisec Austria GmbH will resume with a lecture revolving around the research project ‘Membranes for Windows’ (MEM4WIN) involving 12 industry and research representatives.

The aim is to develop quadruple-glazing from ultra-thin glass, into which organic PV, solar thermal segments and even OLEDs can be integrated in addition to a light-directing and shading system made up of micro mirrors. Mader will parti-cularly focus on the technologies for manufacturing quadru-ple IGUs from thin glass that were developed as part of this project. These help to achieve weight reductions of over 50 per cent and cost reductions of up to 20 per cent.

MEM4WIN will also be a subject covered in the talks delive-red by Hermann Issa from Belectric OPV GmbH and by Mirco Franke from Energy Glas GmbH. Issa will explain technologies for integrating organic PV and solar thermal elements in qua-druple IGUs and Franke, whose company is to take on pro-duction of this glass, will present the product quadruple IGU

Immo Trübger from JSJ Jodeit GmbH will then share a pro-cess for continuous chemical glass tempering developed by his company with the audience. The line is fed continuously and – unlike conventional methods – the manufacturing pro-cess is not intermittent. Even large-format custom products are fast and easy to temper this way.

Dr. Jens Ellrich from Grenzebach Maschinenbau GmbH will conclude the event. He will show new trends and perspectives

-cient ways.

The host for the afternoon session will be Dr. Martin Kilo of the Fraunhofer Institute for Silicate Research ISC.
