- Function drawing
Two synchronized cameras record the ends of the cut product (tread, side wall). The edges are detected in the image with the aid of a special algorithm. After prior calibration of the two cameras to each other, the length measurement system can finally determine the length of the measured tread.
Area of use
The length measurement system is used at the end of the extrusion line for quality documentation and for sorting out material that is outside the tolerance limits.
The EL-Length length measurement system is installed after the skiver. Due to material shrinkage, it is recommended that the measurements are taken as close as possible before the booking station. Only at this point has the tread almost reached its final length.
