Space restrictions, a frequent concern in web installations, can often be overcome by turning the web to allow for stacked equipment. However, conventional turner bars or sweat rolls require physical contact which can damage the web surface and cause web creasing. MEGTEC offers a better solution - MEGTEC Air-turns.
MEGTEC Air-turns use a cushion of air to float the web as it is turned. No surface-to-surface contact is required. Productivity improves because marking and other contact-related defects are eliminated. Air-turns are a safe, effective and reliable method for changing web direction.
They can be designed to operate smoothly at web tensions as low as 0.25 PLI and as high as 5 PLI. The unit's lateral sectors permit selective air pressure adjustment across its entire width, allowing the air turn to compensate for cambered webs and uneven tensions. A sensor automatically adjusts supply air to maintain consistent web-to-surface clearance. The result: excellent transport with no drift or flutter.
