Abstract
A method of impacting a flow of fluid, preferably water, onto a cable which comprises an outer jacket and a plurality of coverings on metal wires therewithin, to simultaneously remove a substantial majority of the outer jacket, and at least some of at least one of the coverings, on the metal wires.
Claims17
A method of simultaneously removing an outer jacket, and a substantial majority of at least two coverings, on at least two of a plurality of covered metal wires contained there within, comprising:
- A) providing a system for use in simultaneously removing an outer jacket and coverings on a plurality of metal wires contained there within, comprising:
- a) source of water pressurized to at least 4,000 psi;
- b) at least one nozzle for expelling water in a jet, and means for orienting said at least one nozzle;
- c) means for positioning a length cable which comprises an outer jacket and a plurality of coverings on a plurality of metal wires;
- B) causing a length of cable to be positioned in said means for positioning a length of cable in a manner which allows it to be slid through said means;
- C) while causing said length of cable to be slid through said means for positioning a length of cable, causing said at least one nozzle to be oriented so that water ejected therefrom impinges upon said length of cable, and causing water to be ejected from said nozzle as a jet;
- such that, in use, water provided from said source of pressurized water is expelled at a pressure of at least 4,000 psi from said at least one nozzle as a jet and is directed to impinge onto said length of cable at an acute angle of incidence thereto, while said length of cable is secured in said means for positioning a length of cable, said acute angle-of-incidence being effected by orienting said at least one nozzle;
- wherein the impact of said water with said outer jacket and said plurality of coverings on said plurality of wires simultaneously causes a substantial majority of said outer jacket and said coverings on at least two of a plurality of covered metal wires contained there within to be simultaneously removed from said underlying metal, at or near the location at which it impinges onto said cable, by a wedging action between said covering and said underlying metal.

- A) providing a system for use in simultaneously removing an outer jacket and coverings on a plurality of metal wires contained therewithin, comprising:
- a) source of fluid pressurized to at least 4,000 psi;
- b) at least one nozzle for expelling fluid in a jet having an elongated major and shorter minor axis lengths, and means for orienting said at least one nozzle;
- c) means for positioning a length cable which comprises an outer jacket and a plurality of coverings on a plurality of metal wires;
- such that in use fluid provided from said source of pressurized fluid is expelled at least 4,000 psi from said at least one nozzle as a fan shaped jet and is directed to impinge onto said length of cable at an acute angle of incidence thereto, while said length of cable is secured in said means for positioning a length of cable, said acute angle-of-incidence being effected by orienting said at least one nozzle;
- such that impact of said fluid with said outer jacket and plurality of coverings on said plurality of wires simultaneously causes a substantial majority of said outer jacket and of at least two coverings on at least two of a plurality of covered metal wires contained therewithin to be stripped from said underlying metal, at or near the location at which it impinges onto said cable;
- B) causing a length of cable to be positioned in said means for positioning a length of cable in a manner which allows it to be slid therethrough;
- C) while causing said length of cable to be slid through said means for positioning a length of cable causing said at least one nozzle to be oriented so that fluid ejected therefrom impinges upon said length of cable, and causing fluid to be ejected from said nozzle as a fan shaped jet;
- such that interaction between said ejected fluid and said outer jacket simultaneously causes a substantial majority thereof, of at least two coverings on at least two of said plurality of metal wires to be removed from said underlying metal, by a wedging action between said covering and said underlying metal.
