optical Inline Measurement of Sheet Geometry

The system imess S4 offers 100% inline control of the sheet geometry in cut-to-length lines. The lengths of the diagonals are subtracted to calculate the rectangularity. The measurement is conducted behind the cut.

Detection of all sheet corners for geometry measurement

[/ultimate_heading]

The system consists of a fixed and a traversing portal with two cameras each. The sheet edges are recorded after the trigger signal release. The construction covers flexible sheet lengths and widths.

Measurement of each sheet

The system checks the dimension of each individual sheet even at high belt speeds of up to 240 meters per minute. Also, large sheets of 2100 mm width and 8000 mm length are reliably detected and inspected by the system.

Complete documentation

The measurement characteristics of each sheet are fully recorded. The measurement log can be exported and saved for internal documentation.

Construction in steel or granite

The system operates reliably and with high accuracy even in rough environmental conditions. The construction can be either in steel or granite. Granite provides better accuracy, but is only used for small installations.
