Erhardt+Leimer presents two new inspection technologies at ITM 2022

At ITM the Erhardt+Leimer group will present, along with its proven systems and devices for web automation, two new inspection technologies, a seam sensor and a metal detector, for the detection of cross-seams and pieces of metal in the web. With these devices, production processes can be optimized and made more reliable.

New inspection technologies for improved

Sensor acquires cross-seams as reliably as the human eye

The seam sensor marketed with the identifier SI 1001 detects, optically and therefore without contact, any type of seam on printed or single-color fabrics. New software algorithms make it possible for the first time to acquire cross-seams at the level of human perception. Along with a light transmitter and a matrix camera with lens, the sensor also includes a WLAN card for reliable communication with a smartphone, tablet or any other mobile terminal device. A dedicated app is also available using which, for instance, special seams can be tested offline. If a cross-seam is detected, a digital output in the sensor is switched so that, depending on the machine, for example the calender rollers can be opened, the shearing blade raised briefly or the seam left to run through the digital printing press without printing. The seam sensor can also be used to calculate the running meters per batch.

Metal detector with segment-by-segment evaluation

During the production of textiles, small metal particles find their way into the web due to the various processing steps. If these particles are not all detected, extremely costly damage may occur on the downstream calender rollers and shearing tools. In addition, there is also a risk of catalytic reactions in wet finishing. As a result, whole web sections are often converted into scrap. The metal detector ELMETA MDA 1005 / 1006 reliably and accurately detects the smallest metal particles over the entire width of the web. Per segment ?(300 mm) a signal LED on the sensor indicates the position of the metal particle in the web. The metal detector can be used for dry and damp web textiles, non-woven fabrics and carpets. Its function is assured at production speeds from 2 to 500 m/min.

Web cleaning for various application areas

ELCLEAN is a modular web cleaning system for the removal of dust and similar soiling in production lines where there is only little space. The system consists of components such as brushes and fabric rollers, as well as components that operate without contact such as powerful fans and a highly efficient vacuum system. The system is equipped with all components or only with certain components depending on the application. Suitable filter systems make possible straightforward, reliable disposal of the soiling. The system is available in both a cantilever version for narrow webs and with support on both sides for wide webs. It can be integrated into production lines or operated as a standalone machine.
