FOR over 70 years SAMP has been
developing and producing wire and
cable manufacturing machines, which are
synonymous with precision and quality of
the final product all around the world.
Extensive research and the continuous
improvement of existing technology
recently led to the development of
the new SAMP double-twist bunching
machine platform, which is designed for
reels with a flange diameter in the range
of 250-1,250mm and up to a total weight
of 4,500kg when filled (in case of copper
strand).
In developing the new platform, the
targets were:
• Energy consumption reduction due
to the implementation of low energy
consumption bows
• Ability to run the machine without
human intervention thanks to the
SAMP automatic traversing system,
including:
• Automatic detection of the reel
dimensions
• Automatic traversing adjust
• Programmable strand tension by load
cell dancer
• Low preventive maintenance
• Pay-off system integration with wire
break detection
• Energy efficiency architecture for high
power factor (cosφ)
• Unique drive and system control
platform for all machine types
• Integrated motor power unit installed
inside the cradle for electronic
machines
• Communication based on safety
integrated industrial wireless
technology
In the electronic series the drive system
is based on an integrated motor power
unit (IPU), installed inside the cradle. The
drive system is supplied from the outside
through a bus whereas all communications
between the external control cabinet and
the motors is based on safety integrated
industrial wireless technology.
The models BM 630 E, BM 800 E and
BM 800 C have the IPU fully integrated
in one unit (motor and drive), while
the BM 1250 adopts standard motors
with drives installed in a cabinet on the
cradle. Due to the compact structure of
the slip-ring and brush-holder system,
maintenance operations are reduced to
a minimum.
For all bunching machines, SAMP designs
its own bows which are aimed at:
• Reducing energy consumption thanks
to the aerodynamic shape
• Minimising the wear of eyelet and
wire path
• Diminishing the damage of wire
surface, important for stranding
electroplated wires (ie tinned, nickel
plated copper, etc)
• Decreasing the damage of insulated
cores surface
• Open bows are available with carbide
or ceramic eyelets or rollers for bare
and coated wire, aluminium wire, bare
strands and insulated cores
