XL frame welder cuts
cycle time by 1/6
The latest ROWELDO XL frame welder
from Rottler & Rüdiger now makes a perfect
SWISSPACER warm edge frame in less than 25
seconds with a new robotic ‘speed-up kit’.
and sturdy 900 x 900mm frame in less than 30
seconds.
Andreas Geith, Managing Director of
SWISSPACER, says: “Until now, cycle times
for traditionally bent spacer bars and
welded SWISSPACER spacer bars have been
almost identical. The ‘speed up kit’ is a great
advancement and makes perfect welded frames
in less than 25 seconds.”

performance fully-automated welding machine
that’s ideal for large-scale sealed unit makers.
It’s cutting production cycle times by one-sixth
for Italian sealed unit manufacturer Predari
Vetri. The new robot welder with the ‘speed-up
kit’ uses four generators – two more than
previous versions - to generate more rapid
energy pulses, so corners can be welded even
faster than before. The profile feed-in has
been optimised and the milling length now
automatically adapts to the width of the spacer
bar. The results: the IGU maker achieves time
savings of around 17%. The standard sized
ROWELDO is still capable of creating a stable Daniele Predari, MD of Predari Vetri explains:
“As far as we can see, there are no faster
options on the market. Any of our orders can
include different frame sizes, spacer bar widths
or colours. That is why the quick profile change
is another advantage for us. We had reached
maximum output in terms of cycle times with
the bending machines. The increased efficiency
gained from the new Roweldo XL means
that two employees from frame production
are now free to work on different tasks. The
speed-up kit also helps us handle production
peaks. We are one of the biggest IGU
Formed in 1998 SWISSPACER is part of
the Saint-Gobain group. The company has
experienced massive growth in the UK in
recent years, and in 2011 became the No.1
warm edge spacer bar brand. Its outstanding
thermal performance and no-investment
needed price benefit has been a key advantage
that has attracted sealed unit manufacturers
and window fabricators and fuelled its growth.

bar and SWISSPACER ADVANCE gives
excellent performance at affordable prices.
All SWISSPACER spacer bars have a High
Tech Gas Barrier for long lasting results.
SWISSPACER is ideal for triple glazing and
is No.1 for Passivhaus – 85% of Passivhaus-
approved windows have SWISSPACER inside.
The manufacturing and head office is in
Switzerland, with further manufacturing facilities
established in Germany and Poland. Much
investment is taking place to expand production
manufacturers in Italy and we always want to
make the best products.”
When visiting his customers, Daniele now
always brings a ready-welded SWISSPACER
frame with him. “You can see the difference
and how much better it looks than a bent
frame immediately,” he says. “Our customers
want straight, stable profiles and a matt surface
without visible connecting points. The welded
90° corner fits perfectly. Our customers
are also able to differentiate themselves on
the market in this way. Some of them have
already asked to be supplied exclusively with
SWISSPACER.”
Andreas Geith adds: “Some customers only
compare the price per metre. What drives us,
however, is producing an overall concept of
competitive advantages for our customers –
from a good price, high quality and the best
physical properties to the fastest processing
and excellent service.”
Existing Rottler & Rüdiger machinery,
depending on the year of installation, can
be retrofitted with the speed-up kit or the
recently launched “Fill-it” technology.

capacity to ensure that SWISSPACER is able to
satisfy the dramatic ongoing growth in demand
for its high performance warm edge spacer bar
products.
SWISSPACER’s structural superiority
means it can be used in all types of insulated
glazing units. It is also suitable for use in
roof glazing or curtain wall facades. It has
been specified in many well-known buildings
including 30 St Mary Axe (the Gherkin) and
the HSBC Building in Canary Wharf.
