Kevlar Fan and Trim Device for Optical Cables

      This device is capable of automatically separating the optical
fibers from the Kevlar strands while spraying and trimming the
strands to length.

                            (Image Omitted)

      The cable (1) is inserted in feed tube (2) and up into the
fanning area (3) (see Figure 1).  Pressurized air is directed through
a port in circular cutter (8) downward into plunger (7) and out
around conical end (7).  As the cable (1) is fed upward slowly into
the air flow, the strands of Kevlar are distributed uniformly out
through the gap between the conical end (7) and the counter sink (3).
Simultaneously, the more rigid optical fibers travel straight up into
the air passage (5) and become isolated from the Kevlar.  The air is
now turned off and the upper plate (9) descends allowing the
spring-loaded plunger (10) and the housing (6) to clamp the Kevlar
strands securely against the urethane pad (4).  At this point, the
circular cutter (8) is rotated and is forced down slicing through the
strands and into the urethane pad (4).  Upon completion of the cut,
(9) is retracted and the cable removed with the strands trimmed to
the specified length.
