Abstract: A cable separator including a pair of slotted rolls that define uniformly spaced apart slitting or shearing sites which are spaced from one another by a distance corresponding to the conductor spacing of a flat cable. A guiding structure at the inlet of the slitting sites for guiding the flat cable thereinto at a proper transverse position to assure that slitting takes place between adjacent conductors. The guiding structure has a plurality of longitudinally extending spring loaded ribs that are spaced from one another by an integral multiple of the interconductor spacing of the cable. A pivotal clamping frame mounted at the inlet of the guiding structure and a mechanism for adjusting the clamping frame to adjust the distance over which the cable conductors are separated by the apparatus.
