Stripper: From bare basics to stripped metal

To most people, a stripper car is the cheapest model on the lot. No air conditioning, no power windows, no leather seats, no sound system worth hearing. It is a vehicle reduced to its essential function: four wheels, an engine, seats, and steering. The word borrows from the everyday sense of strip, to remove clothes or covering, and applies it to the removal of luxury and comfort.

On the shop floor, a stripper plate serves the opposite logic. It removes material from a workpiece, but it does so by separation rather than addition. In the stamping and die-cutting trades, a stripper plate is mounted on a punch die. After the punch descends and cuts or forms a shape into sheet metal or plastic strip, the stripper plate holds the material in place and separates it cleanly from the punch as the tool retracts. Without it, the scrap or finished part would cling to the punch and jam the machinery. The plate is not luxury removed; it is waste removed, and precision required.

Cotton growing brought another sense to the word. A cotton stripper is a mechanical harvester that removes bolls, the seedpods containing fiber, from the plant. Modern strippers use rotating spindles or other mechanisms to pull bolls from branches, ripe or unripe alike, and move them into a collecting chamber. Like the stamping plate, it performs a separation; unlike the car, it strips something that still has use and value, gathering it for later processing.

The metaphor of stripping connects all three. In each case, something is removed: luxury from a car, material waste from stamping dies, fiber pods from cotton plants. The car stripper removes what is wanted but not essential; the die stripper removes what is not wanted; the cotton stripper removes what must be harvested. All three words rest on the same physical action, separation by force or mechanism, applied to different industrial and commercial problems.
