The spinning frame is an Industrial Revolution invention for spinning thread or yarn from fibers such as wool or cotton in a mechanized way. It was developed in 18th-century Britain by Richard Arkwright and John Kay. The spinning frame is an Industrial Revolution invention for spinning thread or yarn from fibers such as wool or cotton in a mechanized way. It was developed in 18th-century Britain by Richard Arkwright and John Kay. Richard Arkwright employed John Kay to produce a new spinning machine that Kay had worked on with (or possibly 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 byLewis Paul to stretch, or attenuate, the yarn. A thick 'string' of cotton roving was passed between three sets of rollers, each set rotating faster than the previous one. In this way it was reduced in thickness and increased in length before a strengthening twist was added by a bobbin-and-flyer mechanism. Too large to be operated by hand, the spinning frame needed a new source of power. Arkwright at first experimented with horses, but decided to employ the power of the water wheel, which gave the invention the name 'water frame'. For some time, the stronger yarn produced by the spinning frame was used in looms for the lengthwise "warp" threads that bound cloth together, while hand powered jennies provided the weaker yarn used for the horizontal filler "weft" threads. The jennies required skill but was inexpensive and could be used in a home. The spinning frames required significant capital but required little skill. It can also be used for many purposes for weaving.
