6.0 TAPE
SPLICING
Care
should
be taken
in splicing
tapes to help prevent
err
oneous
reading.
If
a rough
joint
is
made,
the leading edge of the tape catches
the star
wheel
(when
reading no-hole)
so
that
it starts
to roll over the splice
.
This action,
represented
in Figure 17a,
does not
produce an erroneous
reading in
itself,
but if the joint is just forward
of
a perforation,
the star wheel
,
after
r
olling over
the
rough edge, straddles the perforation as shown in
Figure 17b,
and
the
character
will not
be
read
.
