On the eve of the Industrial revolution it took at least five spinners to supply one weaver. Lewis Paul and John Wyatt first worked on the problem in 1738, patenting the Roller Spinning machine and the flyer-and-bobbin system, for drawing wool to a more even thickness. Using two sets of rollers that travelled at different speeds, yarn could be twisted and spun quickly and efficiently. However, they did not have much financial success. In 1771, Richard Arkwright used waterwheels to power looms for the production of cotton cloth, his invention becoming known as the water frame.
