Straightening & Finishing
CARTACCI Ltd offers complete finishing
lines, andcurrentlyhas inproductiontwo lines
designed for an important Italian customer.
Increased efficiency through innovation
One line is to be used for the production of
cylinders with diameters up to 235mm, and
the other line is for the production of shock
absorbers with diameters up to 70mm. Both
lines include pointing machine, drawing,
straightening, cutting, chamfering, control,
bundling, drainage, weighing and automatic
wrapping systems.
The equipment has been designed to
limit handling and storage, both to ensure
high productivity and quality of surface finish
and to limit the use of manual intervention of
operators thanks to its entirely computer-
based systems.
Cartacci has also introduced its
straightening equipment to Canada. The
straightening machine and its handling
equipment were designed for welded tubes
with upset ends, with a straightening process
in hot conditions (up to 650°C). Operation of
the straightener is based upon sophisticated
logic and advanced technological solutions.

SHUSTER-METTLER Corp, USA, is a
manufacturer of tube, wire and shaped
stock straighteners. The company has
developed a series of self-feeding, high
speed straighteners for use in the tubing
industry, to straighten tubing in-line or from
coils.
The Shuster models 2GRS, 3GRS,
4GRS and 5GRS gear driven tube
and bar straigheners do not rotate
the material during the straightening
process, but use eight vertical rolls and
eight horizontal rolls to straighten and
feed the tubing. The four models of
powered straighteners cover thin wall
tubing in sizes from 3.2 to 76mm (0.125"
to 3") outside diameter. Straightening
rolls are precision ground to size, in
order to avoid deforming the tubing
during the straightening process.
The straighteners can be manufactured
for speed ranges to meet the user’s
requirements, up to a maximum production
rate of 300m/min (1,000ft/min). Machines
can also be manufactured to customer-
specified pass-line height.
For continuous straightening, a single
motor and an AC inverter drive is used on
all GRS machines. A servo drive is also
available on these machines, for feeding
precise lengths into a press or other inline
Straightening and finishing machinery and techniques
equipment. The company also manufactures
a complete line of non-powered two-plane
roll type Shuster tube straighteners. 21
models are available, covering thin wall
tubing sizes from 1.1 to 47.7mm (0.045" to
1.875") OD.
Where straightness tolerances are closer
and when feeding smaller tubing sizes from
coils, the company offers rotary type tube
straighteners.
