DEVICE AND METHOD FOR CALIBRATING A ROLLER LEVELLER MACHINE BY MEANS OF AN INSTRUMENTED BAR

摘要

The device has a rigid measuring bar (8) placed in position in a flattening direction between lower and upper rollers of a leveler. The bar has contacts (81) reproducing action and mechanical characteristics of the lower rollers when placed above the lower rollers. A thin metal plate (82) placed on the contacts has extensometers (83a, 83b) to measure elastic deformation of the plate during effected pressing on the roller-flattener. An independent claim is also included for a method of calibrating a roller flattener.
