Abstract
A method and apparatus for refinishing or recutting grooves formed on the outside of rollers, especially rollers employed in paper making machines. The grooves are provided to facilitate drainage of water from a watery web carried by a felt entrained about the grooved roller. The grooves in such rollers can become obstructed by foreign matter and can decrease in depth as the roller wears and must occasionally be refinished or recut to provide for maximum water drainage.
