  • Patent number: 5727914
    Abstract: Apparatus for removing surface irregularities, e.g. high spots, from the outside jacket or covering of a fiber optic cable. The apparatus includes sets of alternately spaced relatively thin blades, e.g. razor blades, accurately positioned on respective movable opposing slide assemblies with the mutually facing edges of the blades including a small groove or notch machined therein so as to form a round bore having a diameter equal to or slightly greater than the outside diameter of the cable's jacket when two sets of blades on the opposing slide assemblies are brought together in meshing relationship whereupon the surface irregularities on the jacket are removed by scraping or shaving of the cable's jacket when the fiber optic cable is pulled through or otherwise passes through the bore formed between the blades.
