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

It met with violent opposition and he fled from Lancashire to Leeds. Though the workers thought this was a threat to their jobs, it was adopted and the pressure was on to speed up carding and spinning. The shortage of spinning capacity to feed the more efficient looms provided the motivation to develop more productive spinning techniques such as the spinning jenny, and triggered the start of the Industrial Revolution. Hargreaves kept the machine secret for some time, but
