New camera system and IIoT Application Server increase the yield in float glass production.
By means of the camera system Float Scan Edge-digital (FSE-d) Grenzebach launches a new version of the well-proven FSE camera system into the market, which will increase yield in the cold end of the flat glass production. The system supplies fundamentally important information for the optimized cutting to size of the glass ribbon. This system is available as new device as well as add-on kit for equipment already installed. The cutting equipment allows even more accurate adjustment, so that a bigger portion of the available glass ribbon can be used. In the case of schedule preventive maintenance, the maintenance staff gets significant support through new assistance systems. The further development is based on 30 years of experience with the manufacturing of corresponding camera systems. FSE-d can be directly integrated into the digital system by means of the Grenzebach Application Server. 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 values adds; higher yield, higher quality, easier processes, further networking and more data safety.
Precision for the cut-to-size optimization system
The Float Scan Edge system extends over the complete width of the glass ribbon - and detects with two single cameras constantly providing useful information: The system detects the accurate position of the glass ribbon on the conveyor system two outer edges of the glass ribbon and more precise position of the so-called knurl marks on the glass ribbon. The limits of the glass ribbon can now be detected with even more precision. “This helps to precisely calculate the maximum useful width of the available glass ribbon and to transfer it to the cut-to-size optimization system. The core piece at the cold end of the float line works even more effectively and the net width of the glass ribbon rises. By means of integration of all supplied information via the Grenzebach Application Server, the data can be interconnected and analyzed in the overall inspection. Concrete factors for further optimization are still available”, explains Peter Seidl, Product Manager Business Unit Glass at Grenzebach.
The developed camera system includes three decades of experience regarding this task. Especially as the position of the knurl mark can be determined even more accurately and more reliably, it is possible to come closer to the knurl marks when cutting. The rejects produced are minimized and the net glass ribbon gets wider. In short: The new camera brings more square meters of glass and the yield rises.
The new Float Scan Edge-digital can be used for glass ribbon widths of 1700 to 6900 mm; and can also be used for color glass with hardly distinguishable features in the glass.
The system supplies the following information:

“The software tools for picture processing allow among other things an automatic calibration of the system. This allows to significantly support the maintenance staff by means of the assistance system in the case of recurring tasks”, adds Peter Seidl. The system detects increasing pollution and provides hints to maintenance at an early stage. Besides electronics, the mechanical system was significantly improved as well. For this reason the optical path for the detection procedure was changed and the camera directly faces onto the glass surface. Adjustment and cleaning of deflecting mirrors are no longer necessary; another significant plus in the maintenance comfort.
FSE – decisive for the cutting result
The use of Float Scan Edge digital is a concrete support in process inspection for production and cutting technology and supplies important information for product and process supervision, quality control and back-tracking of sequences and settings. Seidl: “Offering a hand-tight value added for our customers – that is the most important motivation with the development of product up-dates. The Float Scan Edge contributes to more yield, higher qualities and resource saving for new and existing equipment.”
Gathering, analyzing and the usage of data
For the experts of production and processing technology, the new camera system is also a constituent module for further networking in the digital glass production. “The Float Scan Edge clearly contributes to gather, use and analyze information and data, created in the value-added chain of glass production.” Of course, the FSE-d can be integrated into the IIoT (Industrial Internet of Things), in order to digitally show the complete process of production for the warehouse down to the user. For this purpose, a local IIoT platform, the Grenzebach Application Server, was developed in-house for all industrial applications - with continuous expandability to Cloud Computing.
Simple up-grading to the digital system
“To be a strong partner to our customers over the complete life cycle also means to us to take the situation of the existing equipment into consideration with every new development”, says Florian Nagler, Head of Global Service Sales at Grenzebach. It goes without saying that the advantages and possibilities of FSE-d are also available to those customers, working with the well-proven analogous predecessor model for already many years. The solution: an uncomplicated service up-date kit, including all components required for the up-grade from analog to digital. The housing of the camera system is conserved, only the electronic components and the software are replaced. This allows to the existing customer to also profit from the new highly efficient and long-lived illumination.
Remote capacity down to the separate camera
Make production technology as long-lived as possible and support with hand-tight service: FSE-d offers remote access down to the single camera. This is available, lived service according to the understanding of Grenzebach. “We develop service upon the principles of classic product management – in order to extend our customers' equipment operating lifetime, to generate additional value and to implement suggestions and needs of our customers at an early stage by means of intensive exchange.” For this purpose, hardware, software and communication inseparably interact. For the communication and collaboration with the customers, Grenzebach pulls out all the digital stops - and besides every equipment operator has a central contact person in service.
The Float Scan Edge system extends over the complete width of the glass ribbon - and detects with two single cameras constantly useful information: This way it detects the accurate position of the glass ribbon on the conveyor system, the two outer edges of the glass ribbon and further more the precise position of the so-called knurl marks on the glass ribbon.
Here, the cutting technology is shown, working on the basis of the previous camera system. On the left side, you can see the gross cutting tool and on the right side the cutting tool for the net cut. The distance between the net cut tool and the knurl mark seems to be comparatively quite big. By means of the Float Scan Edge-digital, users can completely use this optimization potential: By means of the cutting tool, they get very close to the top roller trace and the net glass ribbon gets wider.
International premiere in Düsseldorf: At the glasstec the new FSE-d (Float Scan Edge-digital) was pre-sented for the first time. On the left side in the picture, you see the new version of the camera system, by means of which the position of the top roller trace can now be determined even more exactly and reliably. This leads to more square meters in glass and the yield rises.
On the right side in the picture you see the well-proven analogous predecessor model, which can be equipped with an uncomplicated service up-date kit. The housing of the camera system is conserved, only the electronic components and the software are replaced. And immediately, all functionalities of the development are completely available.

- Glass ribbon drift and wander
- Inner and outer edge position of the knurl marks
- Evaluation of the knurl mark width
- Evaluation of the gross and net glass ribbon width
- Optical distortion in position and expansion of the top roller and edge
- The work with the most recent digital cameras doubled the resolution with 1920x per detection width.
- The temperature range is significantly extended.
- Communication is now possible via network via GigaEthernet – over large distances.
