APPARATUS FOR MEASURING ROLLED SHEET METAL BY CORRECTION

摘要

For cutting metal plate with curved edges so that the transverse cuts are perpendicular to the chord of the curve, the leading plate end is laterally located against an abutment close to the cutter, and the plate is swivelled about the abutment until the plate edge at the position of the trailing end cut is in a position corresponding to the leading end at the abutment. The plate edge position is monitored by extensible feelers which also measure the curvature of the plate edge.
