Arno Arnold GmbH

The basis is an ARNO ARNOLD bellows. With our patented fastening system, telescopic panels are either hinged or rigidly connected to the bellows by means of special fastening clamps, depending on the requirements and space available. The telescopic plates are made of stainless steel and are shaped in such a way that they also have a strong wiping effect.
The Duplet brand includes venetian blinds with movable telescopic plates, bellows with 3-sided telescopic plates and box bellows with all-round protection.

As it is particularly important that the panels close perfectly on the front, the contact pressure of the telescopic panels can be increased even further by using our patented system of rear clamping elements "Outside-in & Inside-out", which are fitted without tools using the QuickStep system, which is also patented. The system of rear telescopic sheets creates a counter-torque in each fold, which enables gap-free pressure to be applied to the sheets on the side under chip impact. Even roof covers made of bellows with sheets can be produced without gaps.

• Reliable combination of quilted or liquid-tight welded bellows and stainless telescopic sheets
• Wide selection of innovative, technical outer materials with application-specific coatings
• Wide variety of shapes (louvres, box shape, angles, etc.) and design solutions (hinged or rigidly connected sheets) - depending on requirements and space conditions

• Proven millions of times over, robust machine protection system that can be tailored to the customer's needs in every respect
• "Duplicated protection" against dust, dirt, heat, chips and liquids - even in the most complex shapes
• Extension limitation thanks to the patented "QuickStep" system and increased contact pressure of the telescopic plates thanks to the patented system for increasing the preload
