Twisted wire brush and method of making

Abstract

A twisted wire brush comprises a twisted wire core, and first and second lengths of spring coil. The twisted wire core comprises a first core wire intertwined with a second core wire. The first and second lengths of spring coil extend about the first core wire, and the second length of spring coil extends about the first length of spring coil. The first and second lengths of spring coil are pressed between the first core wire and the second core wire. In another embodiment, a method of making a twisted wire brush comprises providing a first and a second core wire, positioning a first length of spring coil to extend inside a second length of spring coil, and the first and second lengths of spring coil to extend about the first core wire, and twisting the first core wire and the second core wire about a core axis.
