By using a flying shuttle, a single weaver could produce a wide piece of cloth. The original shuttle contained a bobbin on to which the weft (weaving term for the crossways yarn) yarn was wound. It was normally pushed from one side of the warp (weaving term for the the series of yarns that extended lengthways in a loom) to the other side by hand. Before the flying shuttle wide looms needed two or more weavers to throw the shuttle.
The automation of making textiles (fabrics, clothing, etc) marked the beginning of the industrial revolution.
