Spinning frame stolen from) another inventor called Thomas Highs. With the help of other local craftsmen the team produced the spinning frame, which produced a stronger thread than the spinning jenny produced by James Hargreaves. The frame employed the draw rollers invented by Lewis Paul to stretch, or attenuate, the yarn. The roller spinning process starts with a thick 'string' of loose fibres called a "roving", which is passed between three pairs of rollers, each pair rotating slightly faster than the previous one. In this way it is reduced in thickness and increased in length before a strengthening twist is added by
Hand spinning same time, Richard Arkwright and a team of craftsmen developed the spinning frame, which produced a stronger thread than the spinning jenny. Too large to be operated by hand, a spinning frame powered by a waterwheel became the water frame. In 1779, Samuel Crompton combined elements of the spinning jenny and water frame to create the spinning mule. This produced a stronger thread, and was suitable for mechanisation on a grand scale. A later development, from 1828/29, was Ring spinning. In the 20th century, new techniques including Open End spinning or rotor spinning were invented to produce yarns at rates
