The company’s strip joiners are designed
to provide fast and reliable automated
joining of steel coils, and are built
with ample engineering safety factors
and precision-machined components.
Covering a range from 30mm to 1,010mm
wide and 0.3mm to 16mm thick metal
strip, the joiners offer convenient
solutions to numerous tube manufacturing
applications.
The main line of automatic machines (GG)
is provided with control of strip end position,
feed into the clamps, trim of strip ends, weld
cycle, bead milling, and release. Almost all
functions are automated and integrated in
the machine PLC. Machine layout simplifies
weld inspection by the operator, and all strip
joiners are designed to withstand years of
use in the most demanding applications,
with minimal maintenance.
Mill speed can depend on the ability to
store strip in order to feed a constantly
running tube mill during the stop required
for joining of coil ends. Although speed
and accumulation capacity are essential
parameters to measure an accumulator,
quality materials also require careful strip
handling.
Oto produces space-saving vertical
accumulators, including free-loop types
and the FBS range of machines for soft
handling of light gauges, and a complete
line of horizontal accumulators to satisfy
very large capacity requirements.
Oto’s tube mills are available with wide
range, depth and choice of components,
such as driven or side idle stands. The
company also manufactures quick-change
systems, including the RTC (rapid tool
change) mill and the sophisticated high
precision machine for applications requiring
exact control of mechanical components,
setting repeatability and automatic process
control.
The company’s range of tube mills covers
the production of tubes from 10mm to
219mm diameter. Full integration with other
tube mill components, special designs,
accessories and safety features are also
available.
Oto also offers a range of more than twenty
different models of flying cut-off, including
heavy-duty friction saw cut-offs, cold saw
cut-offs for tubes from 4mm to 220mm
diameter, double shear cut-offs, rotary
double cold saw cut-offs for stainless steel
tubes up to 168mm diameter, shear cut-
offs, and machines for special profiles.
The machines are designed to achieve
higher cutting speed using all currently
available cold saw blades (HSS, coated,
TCT, etc).
Most current and customised software can
be used, enabling setting and recording of
all key cutting and statistical parameters.
