System information

Function

Two point-type laser sensors synchronously traverse the running product (tread, side wall, inner liner, cord) and measure its external contours. The granite frame, on which the precise linear guides are mounted, ensures highly accurate profile measurements thanks to its high temperature stability and reduced vibrations.

Area of use

The high-accuracy online profile measurement system is used primarily in extrusion systems for the inspection of treads and sidewalls as well as inner liners. In hot areas, the profile measurement is used for process control in order to detect deviations from the specification as early as possible and alert the PLC. In cold areas, the profile measurement system is used for quality control and documentation.

Application

The E+L TRISCAN TR system for profile measurement is used in the extrusion line immediately after the extruder (for process control) and/or preferably at the end of the cooling line (for quality assurance). It can also be used for thickness measurements in roller head calenders. The granite frame reduces the thermally induced expansion many times over.
