RAS DuctZipper-V 20.10 from RAS Reinhardt Maschinenbau GmbH is a high-tech electromechanical machine designed for forming and closing the longitudinal lock seam (Pittsburgh type) on small and medium-sized rectangular ducts. The “V” in the name indicates its vertical (V-shaped) construction, which ensures compactness and ergonomics. Similar to the “L” model, it replaces the traditional 2-3 steps (forming the lock, forming the flange, and closing the seam) with a single rapid pass, providing ideal seam quality and high economic efficiency.
Features and Advantages
Standard Equipment
The DuctZipper-V 20.10 comes ready to work with common duct sizes and includes:
Robust and Stable Vertical V-Frame.
Electromechanical Drive.
15-Axis Roller Set: Featuring forming and intermediate rolls for the Pittsburgh lock.
Hardened Steel Rolls: Mounted on high-quality bearings.
Shaft Seal System: Extends bearing life by preventing metal particles and zinc dust from penetrating the internal mechanisms.
Duct Support System: Typically includes three short and three long support brackets for handling small and medium-sized ducts.
Electrical Safety Systems: Including a pull-cord emergency stop switch.
Options
The following options are available for the DuctZipper-V 20.10 to enhance automation and achieve maximum airtightness:
SealJet System: Automatic injection of Mez-Bluemastic-Gel sealant directly into the seam during closure. This ensures a high airtightness class (compliant with VDI 6022 and EN 15780) and provides anti-corrosion protection.
AutoPilot: An automatic clamping system that ensures reliable 2-point pressure on the workpiece throughout the pass and guarantees a simultaneous start of the seam closure from both ends. AutoPilot models are also available for "Sliding seam / S-seam" types.
Duct Return Capability: The support system can be converted into a transport system to return the finished part to the entry zone if repeated operations are required.
