Cut and strip machine for producing cable-sections
A cut and strip machine ( 1 ) for producing cable-sections by processing a passing cable, especially coaxial or optical cable ( 2 ). Cable-sections are cut off from the cable, and on both ends of each cable-section at least one insulating layer can be notched/cut and stripped off. The machine comprises at least one cable feeding device ( 3, 4 ), and a cable processing unit, preferably cutting unit ( 6 ) arranged adjustably transverse to a cable axis, as well as a first cable guiding unit arranged—in a feeding direction ( 5 ) of the cable ( 2 )—in front of said cable processing unit ( 6 ). A second cable guiding unit is arranged behind said cable processing unit ( 6 ). These first and second cable guiding units may be formed as fixed, non-rotating first and second cable centering units ( 7, 8 ). These are arranged in the immediate vicinity of the cable processing unit ( 6 ), and are suitable for centering, preferably straight-line centering, of the cable ( 2 ) on both its sides. At least one of the cable centering units ( 8 ) can be adjusted transversely to the cable axis for effecting its adjustment to the current diameter of the cable to be processed.
