About Arno Arnold
Arno Arnold GmbH is a family-owned company founded in 1864 in Obertshausen (Hesse) and a development partner for flexible machine protection. As the inventor of the bellows for mechanical engineering, the company manufactures bellows, protective covers, roller covers, spirals (WMB) as well as complete machine protection systems and machine protection rear walls, individually designed for installation space, movement, load and service life. The product portfolio also includes telescopic plate brands such as DUPLET (around-the-corner bellows with telescopic plates), WINGS (protection guided over radii), Strapano (dynamic protective cover without bellows), Elegano (liquid-tight, fully welded cover system) and Fix & Finish – ready-to-install complete covers including ready-to-mount sheet metal parts. Production takes place in German manufacturing (Made in Germany) from sheet steel and robust fabrics; in-house material development with approved compounds and material combinations allows tool-free joinable, modularly adaptable constructions. Customer industries include machine tools and CNC machining centers, laser and sheet metal processing systems, robotics and automation technology, medical technology, special machinery and plant engineering as well as traffic engineering/rail technology (among others traction motor ventilation bellows and ventilation ducts for rail vehicles). In the company's own technology and test center, material, flexibility, robustness and traverse speeds

Materials & Processes
Sheet steel
Base material for modern machine enclosures and telescopic plates under high coolant pressures, feed speeds and hot chips.
Robust fabric
Proven material for bellows and flexible protective covers, today combined with tool-free joinable material concepts.
In-house material development
Approved compounds and material combinations enable almost any customer requirement and modular, material-friendly adaptations.
Fully welded systems (Elegano)
Liquid-tight cover systems for CNC grinding centers and compact machine concepts.
Dynamic protective cover (Strapano)
Bellows-free solution for high speeds, high preload, strong sealing and flexible installation positions.
