Customer requirements:
• Sealing tightness against leakage after sealing.
• Uniformed seam quality throughout 450mm length.
Challenges:
• Restoration force from pillow to impact seam open despite mechanical press.
• Several layers due to not precise stretching jig.
• No change of machine structure and other process like stretching tool.
ROPEX solution:
•CIRUS system with active cooling to help seam to be tightened quickly.
Customer benefits:
• Perfect sealing quality: no leakage despite unexpected several layer jump occurring (even 4 layers).
• No warm-up phase for the tools: Thanks to impulse technology, there is no need for a warm-up phase. This enables faster commissioning and helps to increase overall efficiency and save energy.
• One sealing condition: No need to change sealing condition everyday.
• Uniformed Seam quality: CIRUS sealing band provides uniformed sealing temperature over the active zone.
