Machine Description
The Bellow Rolling SPM is a specially designed machine
used to secure and press stainless steel braid over
formed bellows, ensuring a tight, uniform fit and proper
alignment. This process is crucial for maintaining the
structural integrity, flexibility, and leak-proof performance
of automotive exhaust bellows, EGR tubes, and
flexible connectors. The machine uses a powered rolling
mechanism to press the braid onto the bellow surface
without damaging the underlying convolutions.
Features
• Specifically built for pressing SS wire braid over metallic bellows
• Uniform and consistent rolling pressure for secure braid fitment
• Suitable for SS304, SS316, and Inconel braided sleeves
• Adjustable rollers for different diameters and bellow lengths
• Smooth operation prevents braid slippage or damage
• Semi-automatic control with foot pedal or HMI (optional)
• Heavy-duty frame for vibration-free precision pressing
• Fast setup and changeover for different bellow models
