Rolling (metalworking) Wikipedia
Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

Troubleshooting Hydraulic Pumps
If the oil level is low, determine where the leak is in the system. Leaks can be difficult to find. A pressroll hydraulic system at a paper mill in South Carolina had a continual problem with low oil levels, but the leak could not be found. The hydraulic unit was in the basement, and the piping ran up through the deck to the roll upstairs.
