The Flexmaster line of machines comes
complete with an innovative clamping
concept for tool free tube production. The
concept avoids tool changes and cycle time
loss, and any associated costs.
In addition, the production cell Flexistar can
change the diameter automatically without
an increase in cycle time after each rolling
and welding process.
The machine is program controlled
(within the machine parameters), and
any diameter or tube length can be rolled
and welded at a lot size of 1. This totally
eliminates tool costs and changeover
times.
The automatic diameter adjustment for
rolling and welding is the core of the
unit. The tube is guided with the help of
outside positioned, flexible clamping rails
underneath a fixed welding source, which
continuously welds.
With this unique process, the production
from blank to the finished welded tube
is completely automated. The welded
tubes can be immediately processed for
subsequent operations.
The current machine concept is designed
for diameters of 2-16″, with lengths between
10-90″, and metal gauges of 0.008″ to
0.100″. Tubes can now be continuously
produced with a total cycle time of less than
20 seconds.
Typical applications include chimney
tubes, tubes for exhaust systems, catalytic
systems and double/triple-walled tubes
such as metal bellows.

weil engineering, a leader in the
manufacture of special welding systems,
provides rolling and welding technologies
in combination with innovative control
engineering.
This technology is used for the production
of high quality, short tubular products for
the automotive, heating, ventilation and
housing industries.
The company is focused on high tech tube
production lines and laser applications. Weil
engineering especially focuses on durability
and safety, such as machine enclosures
in welding constructions, easy access and
fully automatic handling using standardized
components.
The company will introduce its
revolutionary clamping concept for thin-
walled tubes, which enables short tube
production without tool change. Over
the last couple of years Weil engineering
has developed a broad range of tube
production lines, all of which display a high
level of automation.
