Abstract
An improved cable having a cable core received in an outside jacket characterized by a wax layer being deposited on the outside jacket to improve the gliding properties of the jacket. The wax layer can be provided from either a solution of the wax or from melted wax in container and preferably is applied subsequent to the extrusion of the outside jacket onto the cable core.
Claims16
In a cable having an outside jacket, the improvement comprising layer means for reducing the friction on the surface of the outside jacket, said layer means consisting of a wax layer having a good adhesion to the outside jacket, said wax layer having a thickness of only a few .mu.m and being formed from a wax solution.
A method of providing an outside cable jacket of a cable with a thin wax layer comprising the steps of extruding the outside jacket onto the cable core to form the cable and subsequently applying the wax layer onto the extruded outside jacket, said wax layer being a thin layer with a thickness of a few .mu.m.
In a cable having an outside jacket of a single layer, the improvment comprising layer means for reducing the friction on the surface of the outside jacket, said layer means consisting of a wax layer having a good adhesion to the outside jacket, said wax layer being formed from a wax solution and having a thickness of only a few .mu.m.
