Apparatus for cutting through the sheathing of a cable comprises a cutting wheel and a guide assembly including a guide box substantially enclosing the cutting wheel except for a portion extending through and beyond an end wall of the box. The box end wall abuts a plate extending perpendicular to the end wall and parallel to the cutting wheel. A slot through the plate has side and bottom walls extending parallel to the cutting wheel axle. In use, a cable in the slot extends axially towards and over the cutting wheel. A first cut is thus made in the cable in a plane perpendicular to the cable axis. By positioning the cable to extend axially parallel to the plate, an axially extending second cut is made. By extending the first cut entirely around the cable and intersecting the two cuts, a section of the cable sheathing is removed.
A method for removing a section of a sheathing from a cable having an axis of elongation comprising disposing a sheathed cable within a slot through a plate and extending in a first direction outwardly from said slot and overlying a cutting wheel spaced from said plate, said wheel extending outwardly through an opening through a mounting surface extending perpendicularly to said plate, pressing said cable inwardly of said slot and towards said mounting surface for providing a first cut in said sheathing extending in a plane perpendicular to said cutting wheel axis, and rotating said cable relative to said cable for extending said cut entirely around said cable, disposing said cable against said plate and extending in a second direction perpendicular to said first direction and overlying said cutting wheel, pressing said cable towards said cutting wheel and against said mounting surface for providing a second cut in said sheathing extending in a plane parallel to said cable axis, and moving said cable relative to said cutting wheel along said second direction for extending the length of said second cut.
Apparatus for cutting through sheathing of a cable comprising a cutting wheel mounted for rotation on an axle having an axis of elongation and a guide assembly for guiding a sheathed cable into contact with the cutting wheel for providing a controlled depth cut through the sheathing, said guide assembly including a guide box for partially enclosing said cutting wheel, said guide box including an end wall having an opening therethrough through which a segment of said wheel extends, said end wall forming, with an adjoining plate member, a pair of transverse surfaces for guiding a sheathed cable along a first direction into contact with said wheel, and a slot extending through said plate member from a first surface of said plate member facing away from said end wall to a second surface facing towards said end wall for guiding a sheathed cable along a second direction into contact with said wheel.
