Abstract
The wrapping of articles of indefinite length, particularly cable by locating wrapping material along and parallel to a facing surface of the article and wrapping the material around the article while substantially avoiding frictional contact between material and article. With the wrapping material loosely applied, binding material is applied to cause the wrapping material to tightly surround the article. A forming die for performing the operation, has an arcuate orifice extension connected to the die orifice for guiding an overlapping edge of wrapping material. Apparatus is included which has at least one die. Where more than one die is used, the positional relationship of the dies is determined to prevent the frictional contact between material and article during wrapping.
