the.com/assembly line

means A manufacturing setup where a product moves step-by-step past stationary workers or machines, each adding one piece or task, until it emerges finished at the other end.

from The phrase joins 'assembly' (the gathering of parts into a whole) with 'line,' meaning the fixed path of sequential stations workers stand along. The concept is often tied to Henry Ford's Highland Park plant, where moving assembly lines were put to dramatic use for car production, slashing the time to build a Model T — but the underlying idea had roots earlier, including in meatpacking 'disassembly lines' where carcasses moved past workers each doing one cut. Ford's innovation was less inventing the line than perfecting its speed and continuity, turning a factory floor into a single synchronized machine.
