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
Spinning wheel fibers, which is necessary in the short draw spinning technique, which is often used on this type of wheel. The old-fashioned pointed driven spindle is not a common feature of the treadle wheel. Instead, most modern wheels employ a flyer-and-bobbin system which twists the yarn and winds it onto a spool simultaneously. These wheels can be single- or double-treadle; which is a matter of preference and does not affect the operation of the wheel. The double drive wheel is named after its drive band, which goes around the spinning wheel twice. The drive band turns the flyer, which is the
