MULE. A machine employed in spinning cotton and other fibrous materials. For producing finethreads, a process analogous to that performed with carded cotton, upon a common spinning-wheel,and called stretching, is resorted to. In this operation, portions of yarn, several yards long, are forciblystretched in the direction of their length, with a view to elongate and reduce those parts of the yarnwhich have a greater diameter and are less twisted than the other parts, so that the size and twist ofthe thread may become uniform throughout.
