Windak has announced that the first
of its new generation of automatic
coilers, the FC5, has been successfully
installed in Finland.
According to Urban Bollo, managing
director of Windak Sweden, the
FC5 automatic flex coiler is the
first machine Windak has introduced
as part of a new generation of
affordable automated packaging
solutions. “We understand that the
market today demands cost-effective
solutions that have a short pay-back
time with maximum flexibility and
output.”
FC5 is compact and accommodates
a wide range of cable diameters and
coil sizes. It features fully automatic
coiling with or without a strapper or
binder. Without a strapper or binder
the coil is stretch-wrapped before it
exits the coiling head.

After seven years of intensive research,
Sikora AG has further developed its Fiber
Laser 6003 for the diameter measurement
of bare fibres. Using the new measuring
principle the diameter of optical fibres
with a diameter of 50 micrometers or
more can be measured with an accuracy
of ±0.05 micrometers. This is said to be
ten times more precise than conventional
measuring systems.
Speeds of 2,500 measurements per
second allow extremely precise single
values, and highest accuracy, even at
high draw speeds. Statistical analyses
are directly taken in the gauge head.
By using an FFT-analysis the spin,
vibration frequency and position of
the fibre in the measuring field can be
accurately defined. In addition, other
randomly occurring
non-conformities dur-
ing production and/or
during coating (caused
by variations of line
speed or vibrating
fibres) are discovered
at an early stage. The
statistical distribution of
short-term variations of
the product parameters
is graphically displayed
during production on
the processor system
of the Ecocontrol series
in the form of a cloud
diagram.
The devices are
factory-calibrated and
maintain their accuracy
for the life of the gauge. The gauge
head technology ensures the quality of
the fibre and thus assists in producing
a product that provides reliable data
transfer over long distances without
data loss. The diameter sizing quality
provided by the gauge guarantees a
good connection of optical fibres. The
measuring principle is based on Sikora’s
patented laser-shadow projection
principle.
Sikora also offers the Fiber Lump 6003 T
for lump detection in the drawing tower.
