Erhardt+Leimer will be presenting a new drop stitch matrix sensor for web guiding in conjunction with tube slitters at ITMA 2015. The FE 5204 drop stitch matrix sensor acquires the area around the drop stitch of tubular knitted fabrics. Along with single drop stitches, the sensor also detects a very wide range of different double and multiple drop stitches to be used as the guiding criterion.
Adaptive sensor with convincingly simple operation
The live image provided by the camera is displayed on the colour touch screen of the DO 40 command station.
Operation couldn’t be simpler: The operator can define the slitting position by positioning the tube material in such a way that the drop stitch is visible on the display. Afterwards, pressing only one button is sufficient to save the guiding criterion, i.e. to teach the sensor and start the guiding process. The sensor settings for different kinds of drop stitches can be saved as a recipe and recalled at a later point in time.
Infrared LED light transmitter for optimal contrasts
The drop stitch is made visible for the sensor by means of an infrared LED light transmitter operated in the transmitted light mode. As a result the contrasts are considerably better, compared to white light.
Erhardt+Leimer will present the new sensor at ITMA, which is opening its doors on November 12 in Milan. Moreover, products for the areas of web guiding, web tension control, web spreading, tenter infeed and process control will be on exhibition at the Erhardt+Leimer stand in hall 6, stand F108.
