EFAF heads out East
After the successful launch of the new
automatic coiling line from EFAF in
Europe, the first one has been delivered
to the Far East – to the Yazaki Group in
Bangkok, Thailand.
The coiling line works in-line with
the extruder and is composed of a
horizontal accumulator, the coiler
model Mautomatic 300 Evolution, two
trolleys for the manipulation of the
coils, two automatic toroidal strapping
machines and one coil accumulation
rolling device.
The coiling line has been optimised,
not only mechanically and electrically
(it is possible to control the traction
on the cable with an accuracy of
0.1-0.2kg), but the encumbrance has
also been reconstructed, and this
coiling plant needs only 6.3 x 4m for a
height of 3.3m.
This machine can process cable with
minimum cross section of 0.5mm2 up
to a maximum of 6mm2 .
The cable in Yazaki’s case passes
directly through the towing device
of the extruder in the accumulator
of the coiling line, by excluding the
accumulator of the extrusion line
resulting in a reduction of effort and
cost.
At the exit of the accumulator, the
cable enters the coiler which is
composed of the length measuring
device, coiling head, traversing group,
cutting group and spark tester (it is
possible to add other quality control
devices as well, such as lump and
neck down detector).
If the spark tester detects a fault in the
cable, it generates an alarm that allows
the machine to reject that coil without
stopping the cycle.
The customer can manage the size
of the coils as he prefers because it
is possible to change the height and
external diameter as usual, in addition
to the internal diameter of the coil.
After the coiler, a double turning
manipulator transfers the coils from
the coiling head to the first or second
strapping machine alternatively.
The customer opted for the toroidal
strapping machines. These devices
package coils of different heights
and internal and outside diameters
without the necessity of equipping or
preparing. The number of straps is up
to the customer: in this case there are
3 straps at 120° but it is also possible
to have 4 straps at 90° or only two
straps at 180°.
These strapping machines are also
equipped with a control system on
the bobbin on which the PP-Band
is wound. When the strap is almost
exhausted, an alarm warns the
operator that the roll must be replaced,
avoiding stopping the extrusion line.
This example is only one of the
possibilities that EFAF can offer to
customers.

Horizontal accumulator ▲
Single blade stripper
Using a single blade in centrifugal
motion, Eraser’s Model C100S rotary
blade wire stripper will strip film
insulations up to 11 /2" (38mm) from
solid and stranded wires, Teflon, PTFE,
PVC, nylon, KEL-F, and many more.
Strip length and blade depth
adjustments must be made while the
machine is running. The C100S can
be used to remove insulation slugs
and twist together strands of stranded
conductors. The C100S is CE marked
and meets EU safety standards.
