Eurobend operates through a new state-of the-art production
facility and headquarters, and offices and service centres located
throughout the world.
The wire processing equipment lines include a complete range
of high-output programmable wire straightening and cutting
machines (type “MELC”) designed for heavy-duty continuous
operation within the wire industry. The straightening method
based on the rotor straightening principle using hyperbolically
profiled rollers was invented and introduced by Eurobend
engineers in the early 1980s, setting a standard for the wire
producing and processing industries.
All conventional straightening and cutting machines operate
using two different principles:
• Two-plane roller configuration at 90° to each other
• Conventional rotor straightening with dies
Both systems have advantages and disadvantages. The
Eurobend method is based on the rotor straightening system
but instead of dies, hyperbolically profiled steel rollers are
used. These rollers execute the two fundamental operations of
straightening and feeding simultaneously. This is achieved by
positioning the rollers at an angle to the wire axis and rotating
around it, thereby achieving feeding and straightening at the
same time.
The placement of the rollers at an angle to the wire axis results in
line contact with the wire surface and not in point contact as in
conventional rotors with dies.
When the rotor is spinning and the rollers are feeding the wire
through, there is no sliding friction, but only rolling friction, and
thus the wire surface is not damaged.
The Eurobend straightening method ensures an optimal
straightening quality and consistency without continuous wear
of dies or conventional rollers.
MELC straightening and cutting machines provide users with a
number of advantages:
• Machine downtime is minimised as continuous straightening
mechanism adjustments are not needed
• Straightening of high tensile steel (up to 1,800N/mm2 UTS)
has been achieved without the implementation of additional
apparatus
• Mechanical simplicity of machine construction due to
simultaneous feeding and straightening results in a machine
with stable, constant, efficient and reliable operation
• Cutting of the required length is achieved with flying shear
cutter, while the wire is fed without having to start and stop
or to slow down the speed of the fed wire
• The simplicity of the design allows construction of multi-line
machines depending on the productivity requirements
and the diameter ranges to be processed. Each line works
independently from the others and any combination or all of
them can work together. In addition, each line has a dedicated
collecting bin and can cut the same or different lengths
• By designing the right hyperbolic profile (curvature) of the roller,
combined with the proper surface treatment of the roller and
more rarely the proper coating, the machines can achieve the
desired surface finish on the straightening wire surface
• The different rotor sizes that are available cover diameter
ranges from 4 to 50mm of regular wire, deformed, recessed
or rebar, of any grade (high tensile or stainless steel)

Stainless steel bars price hike
Ugitech and Deutsche Edelstahlwerke, subsidiaries of Schmolz
and Bickenbach Group, have announced a price increase on
their stainless steel bars, wire rod and drawn wire products.
Price increases range up to €50 per tonne and became
effective as of January 2015.
