(under subclass 700) Apparatus including means to enclose an inner part of indeterminate length with a separate, coextensive, hollow, outer, tubular part.
(1) Note. The inner part may be hollow or may be made of multiple parts.
(2) Note. The product of this apparatus may be "armored cable".
(3) Note. This subclass includes apparatus which would be classified in the class for Textiles: Spinning, Twisting, and Twining, except that the apparatus herein includes means to perform a "setting" operation. "Setting" denotes a mechanical operation such as interlocking or deformation, other than the
mere application, which causes the sheath to stay put. See the Search NOtes below.
