The invention relates to an automatic cutting device for printed graphic substrates. The device has a working plane configured to allow passage of a printed graphic substrate along a longitudinal direction (L) and a transverse cutting unit arranged at a slit of the working plane extending in a transverse direction (T) perpendicular to the longitudinal direction (L). The transverse cutting unit is movable along the slit in the transverse direction (T), and has a pair of uprights on which two pairs of counter-rotating blades are respectively mounted, the uprights being spaced apart in the longitudinal direction (L).

A cable stripper is provided which has an adjustable bushing which can be adjusted to accept a variety of differently size cables. The cable stripper is rotated around the cable to strip the insulation from a cable. The cable stripper can be attached to an existing tool to impact rotation of the cable stripper around the cable. The cable stripper includes a bushing having an axial passageway and a plurality of spaced slots which are in communication with the passageway, a plurality of cable retention blocks attached to the bushing, and a blade member mounted on the bushing, the blade member being seated within the passageway. The cable retention blocks are moveable relative to the bushing to pass through the slots and into the passageway to engage the cable mounted within the passageway. A retaining assembly is mounted on the bushing and fixes the position of the cable retention blocks relative to the bushing.
