Curvature sensor arrangement for bending parts, computes workpiece curvature measured from converted and measured displacement of sensing rollers resulting from curvature

摘要

The sensor arrangement computes the workpiece curvature to be measured from the converted and measured displacement of sensing rollers resulting from the curvature. The conversion of the roller displacement is performed using either a string and several pulleys or two series of rollers joined together like segments of a chain.
