Cable Slitter

The multiple wires of flat ribbon cable can be simultaneously separated into individual insulated conductors by using a scissors-type cutter having multiple parallel blades.

The cutting device, shown at A, has an upper group of blades 1 offset from a lower group of blades 2 mounted on a common pivot shaft 3. Each blade 1 forms two cutting edges through cooperation with a mating blade 2 on either side. Blade thicknesses are varied in each group according to cable width and conductor spacing. Heavier blades 4 are used as the outer blades. The blades of each group are separated by ground washers and held in their respective groups by pins 5 for operation as units.

In operation, ribbon cable 6 is inserted between the two sets of blades, as at
B. One group, such as blades 1, is held stationary while the other group is moved. When actuated, the blades cut the insulation and concurrently bend adjacent conductor ends 7 in opposite directions. Wire ends may or may not be bared prior to cutting.
