Flexible Cable Surface Protector

      A design concept to eliminate wear and debris of a long flat
flexible cable that is operated in a horizontal orientation with
sliding contact between the cable surfaces.

      When a flat electrical signal cable is used in a moving
environment and the cable surfaces are in sliding contact, wear
occurs.  The wear generates debris and reduces cable reliability and
life.

      To eliminate friction and wear a material different than the
cable surface is interleaved between the contacting surfaces (i.e.,
stainless steel against nylon, polyethylene, etc.).  A stainless
steel ribbon of the same width as the flat cable is pre-stressed into
a coiled "clock spring" shape when unrestrained.  The ribbon is
attached to a cylinder that it coils or wraps around.  The cylinder
is placed inside the loop of the cable with the loose end between the
contacting cable surfaces.  With cable motion the cylinder rolls back
and forth inside the cable loop rolling up or unrolling the stainless
steel ribbon.

      The loose end of the ribbon can be secured at either the
stationary or moving end of the cable.  The stainless steel ribbon is
guided on and off of the cylinder with flanges attached onto the
cylinder sides.

If the stainless steel ribbon is attached at the stationary cable
end:

1.  and the cable unwraps (i.e., moves away from the stationary
    point), the steel ribbon is spooled off of the cylinder keeping
    the cable...
