Twin/Multi-Line Separation

Cut Hose to Length –
Press
the multi-line hose assembly
firmly and flat against the work
surface with your free hand so
that it does not move. Using a
sharp utility knife, carefully draw
the knife toward you with con-
stant light to moderate pressure,
and a smooth stroke. Multiple
strokes will be necessary to
separate the hoses.
Note
It is important that the knife
blade be perpendicular to the
hose during this procedure so
that the blade cuts only the cen-
ter line of the web. Extreme care
must be taken to avoid cutting
through the cover of the hoses
and thereby exposing the hose
reinforcement. If this occurs, the
hose assembly must be discarded
(
See Figure 1). If the separa-
tion length is greater than that
which can be accomplished
with one continuous, smooth
stroke, then the procedure
should be repeated over shorter
distances always cutting toward
the free end of the hoses.
Measure Separation –
It is
suggested that the separation
length be sufficiently long so
that the swaging or crimping
operation can be accomplished
without risk of kinking the hoses
or tearing the web which could
result in exposure of the hose
reinforcement (See Figure 2).

Apply Tape –
At the option of
the assembler, as dictated by
the installation, a nylon lashing
strap or tape may be applied at
the termination of the separated
length to provide protection
against tearing of the web or
hose covers.

INCORRECT HANDLING
Figure 1
–
Extreme care must
be taken to avoid cutting
through the cover of the hoses
and thereby exposing the hose
reinforcement. If this occurs,
the hose assembly must be
discarded.
Figure 2
–
The separation
length must allow for the
swaging or crimping operation
without damaging the hose.
