RAS DuctZipper-L 20.12-L is a high-performance electromechanical machine from RAS Reinhardt Maschinenbau GmbH, specifically designed for large and bulky rectangular ductwork. The “L” in the name refers to its L-shaped configuration, which allows for processing U-shaped workpieces and closing the longitudinal lock seam (Pittsburgh type) along the entire length in a single pass. This machine simplifies the traditional three-stage seam-closing process into one, significantly increasing speed and reducing labor requirements.
Features and Advantages
Standard Equipment
Robust Steel Body: L-shaped design for space-efficient installation against a wall.
Powerful Electromechanical Drive.
15-Axis Set: Featuring forming rolls and 9 additional intermediate rolls for seam formation and closure.
Removable Guide Profiles: Located on the entry table for easy workpiece loading.
Extended Guide Rail: For high-precision sheet guidance.
Shaft Seals: Protects bearings from zinc particle penetration (galvanized coating debris).
Electrical Connection: 400 V, 50 Hz, 3-phase with a 5 m cable and CEE plug.
Emergency Cable Switch: Pull-cord safety stop across the working area.
Options
To maximize quality and automation, the following key options are available:
SealJet System: Automatic injection of Mez-Bluemastic sealant directly into the seam during closure. Guarantees corrosion protection and airtightness up to Class D.
AutoPilot: Ensures the seam closing begins simultaneously at both ends of the duct and securely clamps the workpieces during the pass for increased accuracy.
Duct Return System: A conveyor system that returns the finished duct to the entry zone, useful if multiple seams need to be processed on a single workpiece.
