A method of conducting one-piece flow in a cell where machines unload parts automatically so that the operator (or operators) can carry a part directly from one machine to the next without stopping to unload the part, thus saving time and motion.

For instance, the first machine in a processing sequence automatically ejects a part as soon as its cycle is completed. The operator takes the part to the next machine in the sequence, which has just finished cycling and ejected its part. The operator loads the new part, starts the machine, and takes the ejected part to the next machine, which has just finished cycling and ejected its part and so on around the cell. The term literally means "load-load" in Japanese.
