Cut the circumferential groove at the specified position of the one side and cut it from the both sides of the cable along the cable feed line through the lateral feed of the blade base, and move the cutter head to move the lateral feed from the circumferential groove to the cable tip. A blade base that has a pair of lateral groove cutting tools that cut the groove and remove the rubber jacket on the same circumference orthogonal to the former, and before and after carrying the cable into the blade base. After entering, it is conveyed in one direction to a predetermined processing position via a feed roll, cut into a predetermined length, and a decoder and servo motor that interlock with a measuring roll that automatically controls the peeling of the required length. It is a cable stripper that is equipped with sequential automatic control of numerical control.

The vertical groove AS _{2 on the} cable C that leaves the left end of the
Direction, and then move the tool rest 10 to the machining position IV in the direction of arrow F
While moving to the left, insert the horizontal split groove BS ₂ to complete the peeling process on the left side, and the next feed drive is carried out from the carry-out side to the outside of the machine through the carry-out port, and the same machining process is repeated and automatically operated. The required number of inputs can be processed.

(Effect of the Invention) Since the present invention is configured as described above, it has the following advantages.

In other words, even a cable such as a large-sized light-duty cable that is thick and long and difficult to handle, for example, a cable with a predetermined length of 11 rice cakes and a length of 10 rice, completes a peeling process in 5 seconds. As a cable stripper that is 1/50 times less efficient than conventional technology and has labor-saving means, it can greatly contribute to streamlining computer-related manufacturing processes.
