Outer Sleeving Removal (2 - 6.5mm Ø Adjustable)
The Kelvar Stripping Tool is a rugged lever-action hand tool designed to
remove any length of Kelvar reinforced protective sleeving from fibre optic
bundles. The tool comprises of two independently adjustable cutting blades
set in opposition within the jaw housing. The depth of cut is regulated by
knurled blade adjusters, situated on either side of the tool, which allows
infinitely variable blade penetration from 0-3mm. Provision has been made for
inserting sleeve guides into the top and bottom halves of the Kelvar Strip jaw;
these simply clip into position and ensure correct location of the lead
throughout the stripping operation.
Setting
l
Select pair of sleeve guides corresponding to lead diameter and locate into
upper and lower halves of tool jaw.
l
With tool in closed position adjust blade depth by turning the adjusters and
observing the gap between the cutters. Note that the blades should NOT
cut all the way through the outside insulation, so as to ensure no damage
to the optical leads inside.
l
Make a trial cut by inserting the lead into the front entry slot of the tool,
depress handle, and pull the tool to the end of the lead maintaining an even
pressure on the tool handle.
l
Remove lead, inspect result and make final adjustments to cutting depth if
necessary.
Operation
l
Insert lead into side entry slot of the tool. (Figure 2)
l
Depress handle and rotate the Kevlar Strip back and forth over the
protective sleeving, release handle and remove lead. (Figure 3)
l
Insert lead into front entry slot ensuring blades come together at the point
of the circular incision. Depress handle and pull the Kevlar Strip along the
full length of sleeving. (Figure 4 and 5) This creates two longitudinal cuts
allowing the Kevlar reinforced protective sleeve to be split and removed
with ease. The remaining strands of Kevlar may be trimmed using a pair of
precision cutting nippers.
Cutting Blade Replacement:
l
To replace both upper and lower blade cartridges remove upper and lower
sleeve guides.
l
Release blade captivating screws, and turn each blade adjuster clockwise.
The blades may be prevented from rotating by using finger pressure or a
small spanner if necessary.
l
Insert new blade cartridges and re-assemble
Note: Do not overtighten blade captivating screws as these also serve to
centralise the blade in the jaw housing.
Stripping of Optical Fibres
Capacity: All fibre optic leads from 15-1000 microns. P.T.F.E. coated wires
0.5-3.0mm O.D.
The optical fibre stripper comprises two blades mounted on spring-loaded
tensioning arms which are in turn fixed on either side of a hollow spindle. The
depth of cut is regulated by the conical adjusting nut situated behind the
blades. The blade adjuster is equipped with a retention screw so that once set
the cutting depth may be permanently locked in position. Provision is made
for inserting a guide bush into the barrel of the tool, directly behind the blades
and also one immediately in front of the cutters. This ensures that the fibre
optic lead is correctly held in position throughout the stripping operation.
Setting
1. Select correct pair of guide bushes corresponding to lead diameter. Fit the
internal guide bush by depressing the tension arms an inserting into the
opening directly behind the cutting blades.

2. Set cutting depth approximately by turning the blade adjuster and
observing the gap between the cutters. Slip external guide bush over the
blade assembly.
3. Open the blades by depressing the tensioning arms, insert the fibre optic
lead, release tensioning arms and take a trial cut by spinning the handle.
Remove lead and inspect result.
4. Make final adjustment to cutting depth and lock blade adjuster in position.
Operation
To operate simply depress tensioning arms, insert lead, (Fig.7), release
tension, spin handle and pull off the sheathing (Fig 8).
The stripped slug is cleared via the hollow spindle of the optic-strip through
the rear of the barrel. Optics of 15 microns or less do not require rotation of
the tool when stripping.
Internal Guide Bush Extraction
Remove external guide bush and insert extractor (supplied) through the rear
of the barrel. Depress blade tensioning arms and eject internal guide bush
through the front of the tool.
Silicon Stripping
Once the P.T.F.E. fibre coating has been removed as above, a thin coating of
primary silicone has to be removed from the optical fibres. The silicon
stripping tool (fig. 9) is a fast effective method of achieving this.
Operation
Light pressure to the spring loaded handles, whilst gently pulling along the
length of the bare fibre, smoothly removes the silicone coating.
Setting
The stripping blades are made of Delrin and are permanently set at an angle
which causes no damage to the light guide even when excessive pressure is
applied during the stripping operation.
Cutting Blade Replacement
Undo blade retaining screws, remove worn blades and replace.

Entfernung der Außenummantelung
(Für Leiterstärken von 2 - 6,5mm Ø Durchmesser)
Die Kelvar-Abisolierzange ist ein robustes Handwerkzeug mit
Hebelbetätigung, mit dem die Kelvar-verstärkte Außenummantelung der
Lichtleitbündel in beliebiger Länge entfernt werden kann. Das Werkzeug
besteht aus zwei einzeln verstellbaren Klingen, die innerhalb des
Backenrahmens einander gegenüberliegen. Die Schnitttiefe (zwischen 0 und
3mm) wird über die gerändelten Stellschrauben auf beiden Seiten des
Werkzeugs eingestellt. Durch das Einlegen von Hülsenführungen in die obere
und untere Hälfte der Kelvar-Abisolierbacken wird das Kabel während des
Abisolierens sicher gehalten.
Einstellung
●
Wählen Sie ein Paar Hülsenführungen aus, die dem Kabeldurchmesser
entsprechen, und legen Sie diese in die obere und untere Hälfte der
Werkzeugbacken ein.
