ROLLER LEVELING MACHINE |
| abstract |
Metal strip straightening machine includes an ultrasonic roll so that a dynamic high-frequency stress on the strip is superimposed on a static tension or flexure. The roll vibrates radially at ultrasonic frequency; its dia. and wall thickness are so designed that a bell mode of resonance which smoothens and flattens the strip. |
