‘An IGU in under 25 seconds’
31st July 2018

The latest ROWELDO XL frame welder from Rottler & Rüdiger now makes a Swisspacer warm edge frame in less than 25 seconds with a new robotic ‘speed-up kit’, says the spacer manufacturer.

The ROWELDO XL is a fully-automated welding machine 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 result is the IGU maker achieves time-savings of around 17 %. The standard sized Roweldo is still capable of creating a 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.”

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.

“We are one of the biggest IGU manufacturers in Italy and we always want to make the best products.”
