Euroalpha technical team has been the first to introduce the multi-

motor technology on rod breakdown machines for non-ferrous wi-

res, in order to achieve LIMITED-SLIP operations and exceed the

performance of conventional slip-type drawing machines.

Euroalpha opted for low-inertia a.c. motors and state-of-the-art vec-

tor inverter drives, to secure best precision speed control through a

maintenance-free system.

Improved algorithm to synchronize motors and minimize slip has

been set up thanks to 16-years continuous research and testing

onto limited-slip technology.

Euroalpha design positively affects operations and maintenance,

improves wire quality and it also brings a significant contribution to

running costs savings:

• energy consumption substantially reduced;

• working lifespam of drawing capstans and annealer’s contact ban-

ds largely extended;

• maintenance operations extremely simplified and less expensive;

• low noise level without any sound-proof cabinet;

• superior quality of finished wires;

• great operational flexibility, to set up the “best” drawing process

for any type of material.

High precision design and manufacturing of mechanical parts, com-

bined with a large use of standard commercial components from

best manufacturers, make Euroalpha equipment a benchmark as

overall reliability and user-friendly approach for operators and main-

tenance engineers.

Continuous and effective operations are guaranteed by our After-

Sales Service well experienced team, and on-site assistance can be

even further strenghtened thanks to the vast and capillary worldwide

presence of our OEMs.

EUROALPHA ROD BREAKDOWN LINES: MILESTONES IN TECHNOLOGY

R1 can be combined with any model of pay-off and take up belonging to the Euroalpha complete and flexible sy-stem. Available versions for special alloys as well as welding wire.

R1 is an innovative compact rod breakdown machine to cope

with space shortage often present in drawing plants: 5 mt long

only.

Capstans are arranged onto two superimposed rows, and they

are all individually motor-driven to perform limited-slip drawing.

Submerged lubrication on the lower row of capstans, and ex-

clusive spray lubrication on the upper row.

Skin-pass and wire polishing module available as optional.

Built-in dancer prevents from any misalignment during

installation, and reduces the total length of the line.

Thanks to its intelligent design R1 provides performance and

wire quality absolutely comparable with the ones of conventio-

nal rod breakdown machines, with capstans arranged onto a

single straight-line and submerged into the drawing lubricant.

But against lower operational costs.

R1 does represent the most cost-effective solution to draw

copper rod, as for capital investment and operational expen-

ses.

R3 can be combined with any model of pay-off and take up belonging to the Euroalpha complete and flexible system.Available versions for special alloys as well as welding wire.

R3 is a very high-performance rod breakdown machine with

capstans arranged onto one single row, which overall project

stands out for ergonomic design, solid construction and flexi-

bility of use. It can be manufactured for drawing 1 or 2 wires

simultaneously, to meet even the most consistent require-

ments in terms of productivity. A special twin-wire execution

for drawing two different finished sizes at different speeds is

also available, in order to enhance the overall flexibility and

productivity of the line.

Skin-pass and wire polishing module available as optional.

Submerged lubrication with fully watertight operations is com-

bined with easy access to capstans and dies during string-up

thanks to a sliding steel bulkhead in front of the capstans, mo-

ving downwards and upwards for string-up and drawing re-

spectively. The entire drawing section is closed by a steel front

door with innovative round design.

Low operational costs are guaranteed by limited-slip technolo-

gy and the clever design of the machine.
