Cable Inspection with AI - nLine sets the standard in quality assurance

Hubert Eberle (nLine): nLine is a highly modern and innovative 360° inspection system for optical quality assurance. It was developed specifically for customers utilising continuous production processes to manufacture cylindrical products such as cables, pipes, wires, cords, or hoses. The system monitors the entire surface of the product in real time and immediately detects any abnormalities. This increases the level of quality, optimises process security, and makes the highest precision and efficiency possible.

Pascal Schwindhammer (HELUKABEL): nLine's precision and adaptability are one of a kind. For example, the system detects surface abnormalities such as scratches and tears and, with the help of AI, learns which abnormalities are tolerable and which are not. Even the most complex product surfaces, such as multicoloured, intricately woven cords, can be analysed with the highest accuracy. nLine is also able to be seamlessly integrated into existing production systems via field bus systems such as PROFIBUS or OPC UA. We are continuously developing nLine in order to flexibly react to customers' individual needs.

Eberle: In addition to the especially high-quality detection of anomalies, the system is defined by its particularly easy setup and operation. Furthermore, this inspection system is installed in the production line. The system is then taught with a so-called "Gut-Muster", or training sample, and immediately knows which specific product characteristics it needs to look for. On-site product training takes less than ten minutes, with analyses beginning immediately after. This AI-aided analysis allows data to be locally and quickly processed inside the device, which saves time, improves data security, and does not require a cloud connection.

Schwindhammer: This exact combination of AI, real-time monitoring, and flexibility allow us to detect and classify defects as early as possible, and to evaluate them according to tolerance ranges – all this before the cable even makes it to the drum. Reaching speeds of up to 500 metres per minute, nLine is also suitable for high-output production and functions with virtually no maintenance required, which is a significant advantage for users.

Eberle: Originally, nLine was a product of the company Wahtari, specialists in AI-based image recognition and automation. It was quickly clear that the quality assurance systems available at the time were not sufficiently efficient and did not offer 360° monitoring. Our vision was to develop a system together with HELUKABEL that works within the production process, is completely dependable, smart, and performs at the highest level. This is how nLine developed from a product into a company.

Does this mean that you originally worked for Wahtari, Mr Eberle?

Yes, exactly. I worked in sales at Wahtari and participated in the initial development of nLine. It was self-evident that I would take the product with me to the new company.
