Device for separating the core and the sheath of a cable and method for separating the core and the sheath of a cable

Device for separating a core and a sheath of a cable, comprising:

• an apparatus configured to feed the cable along a feed axis parallel to a longitudinal axis of the cable up to an outlet passing between at least two knives,
• the at least two knives being configured to cut the sheath over its whole thickness and to form at least two portions of the sheath mechanically dissociated from one another, each knife comprising a cutting front extending in a first radial direction with respect to the longitudinal axis of the cable to cut the sheath,
• at least two ramps extending from the at least two knives, the at least two ramps being configured to maintain the separation between the at least two portions of the sheath and to mechanically separate the sheath and the core up to the outlet by modifying the movement path of the at least two portions of the sheath differently with respect to the feed axis, and
• at least two deflectors arranged down-line from the at least two ramps to receive the portions of the sheath, the at least two deflectors having an outer surface modifying the direction of movement of the portions of the sheath perpendicularly to the longitudinal axis of the core.

Method for separating a core and a sheath of a cable successively comprising:

• providing a cable provided with a sheath surrounding a core, the cable running along a feed axis parallel to a longitudinal axis of the cable and with a feed direction,
• cutting the sheath over its whole thickness by means of at least two knives to form at least two portions of the sheath mechanically dissociated from one another, the two knives extending in a first radial direction with respect to the longitudinal axis of the cable,
• making each portion of the sheath slide on at least one ramp extending from the at least two knives to keep the portions of the sheath separated from one another and to strip the sheath from the core, and to secure the core along the cable feed axis, the at least one ramp having an outer surface extending away from the cable feed axis in the feed direction of the cable to separate the core and the portion of the sheath when the cable runs along the feed axis,
• making each portion of the sheath slide on a deflector to move the portions of the sheath in a second direction perpendicular to the first direction and to the cable feed axis, the core passing on one side of the deflector and the sheath on the other side of the deflector.
