A power loom is a mechanized loom that automates the weaving of cloth through leveraging mechanical power. It interlaces warp and weft threads via mechanisms like cams, gears, levers, and pulleys, replicating motions previously done manually. The mechanization of weaving dramatically increased production efficiency, contributing to the rise of large-scale textile factories during the Industrial Revolution.
Though the idea is older and experimentation predates him, Edmund Cartwright is credited with initiating power loom development with his 1785 patent. His initial versions were rudimentary but they pioneered automated weaving and laid the groundwork for factory-based production. By the early 19th century, improvements had made power looms reliable and widely adopted across Europe and North America, ushering in a new era of textile manufacturing. Cartwrightβs invention marked the beginning of mechanized weaving, drastically reducing reliance on skilled handweavers.
