Roller flattener calibrating device, has thin metallic plate placed on contacts of bar located between lower and upper rollers, where the plate has extensometers to measure elastic deformation of the plate when pressing on roller flattener

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.
