Automatic Insulation Stripping Device for Miniature Coaxial Cable
having a Groundwire with a Special Shielding

      This article describes an automatic wire stripper for miniature
coaxial cables having a ground wire with a shielding consisting of an
aluminum-coated polyester foil.  This foil is pulled off by a special
set of grippers (Z1 through Z5) after cutting the outer jacket with a
CO[2]  laser.

      Cutting into lengths, stripping of both ends as well as cable
feeding and storage proceed automatically.

The process is described with reference to the Figure.

      In a first step, the cable is fed into Z2 and Z3 by feeding
unit Z1.  Then Z2 and Z3 are closed, the cable feeder is driven back,
and the first laser cut takes place.

      Subsequently, the outer jacket and the aluminum overcoat are
stripped by Z3.  The slug is blown out, and a second laser cut for
the inner dielectricum occurs.

When the front end is prepared, Z2 and Z3 will open and Z1 can feed
the wire into Z4.

Z4, driven by a motor-controlled linear axis, pulls the wire out to
the desired length.

      When Z4 has reached the desired length, Z2 and Z3 will close.
A mechanical cutting unit moves between Z2 and Z3 and cuts the wire
to length.

Subsequently Z2 will open, and Z1 pulls the wire out of Z2.

      Z2 moves to the laser position and is closed, now the first
laser cut at the back end of the wire takes place.

      Next, the insulation as well as the aluminum is...
