Ultrasonic sealing machine
with rolling sonotrode

• Amplitude or power, speed and pressure are controlled electronically
• 100% reproducibility of the welding process
• Most of thermoplastic sheets, laminates, textiles and non-wovens are weldable
• Equipped with differential feed; separate drive for sonotrode and anvil wheel; that means smooth, non-distorted seams or the possibility of adding a some fullness
• Process reliability through monitoring of welding parameters with integrated device for the control of the amplitude (so that reliable processing is possible even when sewing over cross seams)
• High production speed
• Touch screen: Simple handling with
  pictograms
• Process reliability by monitoring of welding parameters (constant performance)
• No compressed air required
• 8311 CS: Cut & Seal
• 8311 CS dual: Cut the edges, seal the them and seam a second weld seam  
• New: PFAFF 8311 with long arm
