The ShapeScan is the ideal option when it comes to detecting a particular curvature and warping as a defect. The cupping can also be optionally measured. The ShapeScan T can calculate the curvature or warping via sensors in the cross conveyor. In contrast, the ShapeScan L measures these values in the longitudinal throughfeed. This data is forwarded to the optimization to observe a maximum bending limit per product, for example. The ShapeScan can also be used as a single machine for sorting the curvature.
