Electromechanical Seam Closing Machine RAS 25.15

Features and Advantages

Feature	Advantage
Quick Seam Change	Reconfiguring for internal or external seams takes only a few seconds by swapping the lower roll and shifting the upper roll.
Hydraulic Clamping	The upper roll clamps the workpiece hydraulically (controlled via foot pedal), ensuring reliable fixation and a high-strength, airtight seam.
Automatic Opening	The roll opens automatically upon completion of the seam (triggered by a limit switch), simplifying tube unloading and improving safety.
Doubling Work Length	The 1520 mm mandrel length can be effectively doubled to 3040 mm by flipping the tube, allowing for the processing of ducts up to 3 meters long.
Seam Versatility	The machine operates with the two most common seam sizes: 10 mm and 13 mm.

Design Features

Forming Rolls: Manufactured from hardened steel and mounted on roller bearings to ensure high precision and wear resistance.
Upper Roll: Driven by a powerful geared motor and features knurling (ribbing) for reliable and safe transport of the tube along the mandrel.
Upper Roll Positioning: The roll can be manually shifted into one of three fixed operating positions (for external 10 mm, internal 10 or 13 mm, or external 13 mm) with a simple finger press.
Mandrel (Console): Robust and rigid, providing stability during the seam closing process over the entire length.
