I got a question for you: The flying shuttle was one of the key developments in the industrialization of weaving during the early Industrial Revolution. It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms. The flying shuttle, which was patented by John Kay (1704 -- c. 1779) in 1733, greatly sped up the previous hand process and halved the labour force. Where a broad-cloth loom previously required a weaver on each side, it could now be worked by a single operator. Until this point the textile industry had required four spinners to service one weaver. Kay's innovation, in wide use by the 1750s, greatly increased this disparity.

Answer this question: what invention allowed a single weaver to weaver much wider fabrics?
Let's think first:
The relevant information is: It allowed a single weaver to weave much wider fabrics, and it could be mechanized, allowing for automatic machine looms.
Therefore, the answer is flying shuttle.
