RAS DuctZipper-L 20.10-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

Feature Advantage
One-Pass Technology Maximum Efficiency — forming and closing the lock occurs in a single pass, replacing 2-3 traditional operations.
L-Shaped Design Space Saving — requires 40-50% less space and can be installed directly against a wall, ideal for smaller workshops.
High Processing Speed (15 m/min) Increased Productivity — doubles the workflow speed compared to manual methods, ensuring rapid fulfillment of large orders.
Duct Support System Labor Minimization — the support system holds the weight of large ducts during the pass, often allowing one operator to work instead of two.
Improved Guide Rail Seam Precision — the extended guide rail ensures accurate sheet feeding to the first forming rolls, preventing duct distortion.
SealJet Integration Super Airtightness — optional sealant injection system for the highest airtightness classes required for high-efficiency ventilation.

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.
