One of the products showcased by Erhardt+Leimer at ITMA ASIA + CITME 2020 in Shanghai was the new ELMETA MDA1005 / MDA1006 metal detector with increased accuracy: It reliably detects even very small metal particles across the entire width of the web. Signal LEDs on the sensor indicate the position of the metal particle in the web. The integrated segment-wise evaluation as well as the gain setting and a reset button ensure straightforward commissioning. The device detects metal particles at production speeds from 2 to 500 m/min (depending on the size and material of the particles). The special scanning surface and the aluminum housing prevent damp webs or electromagnetic interference affecting the detection result. The device can be used for dry and damp textiles and for non-woven fabrics. It can be installed in any orientation in any production machine. The only requirement is that there must not be any moving parts, e.g., rollers, installed within an area of 500 mm.
By detecting even very small metal particles, the MDA1005/1006 can prevent extremely costly damage that may occur on the downstream calendar rollers and shearing tools. Furthermore, the risk of catalytic reactions in wet finishing is minimized.
Apart from the metal detector, Erhardt+Leimer also exhibited the ELCUT cutting systems, the ELSMART web guiding and spreading system, the ELSTRAIGHT weft straightening system, the ELFEED tenter guider, ELTENS equipment for web tension measurement and control and the camera-based ELCOUNT pick and course counter.
