Dimensional accuracy of sectional doors

The individual sections of sectional doors are connected with a tongue and groove joint. For a tight and permanently flexible connection, compliance with the nominal dimensions is of decisive importance.Strong temperature differences lead to jamming and consequently to a poor fit of the doors if the dimensions are inaccurate. Therefore, precise inspection of the tongue and groove profiles is important for compliance with the manufacturing tolerances. The measurement is performed with scanCONTROL laser profile scanners. An anchor point is defined in the profile, which provides the reference for all calculations. As a result, all fluctuations within the strip process can be compensated for. These results are transmitted to the production line control room.
