A Multi Bladder Air Adaptor is used along with an air shaft to handle different core sizes without changing the entire shaft. It is especially useful in slitting and rewinding operations where job requirements change frequently, such as in BOPP film, paper, foil, and flexible packaging industries.
The adaptor is fitted over the air shaft and comes with multiple air bladders distributed along its length. When air is supplied, these bladders expand uniformly and grip the core from inside, ensuring proper holding across the full width. This uniform expansion helps avoid issues like uneven tension, core slipping, or vibration during machine operation.
In practical use, a multi bladder adaptor allows operators to convert a standard shaft size into a different core size quickly. For example, a larger shaft can be adapted to run smaller ID cores without needing a separate shaft. This saves cost and reduces setup time, especially in plants where multiple core sizes are used regularly.
Operation is simple—mount the adaptor on the shaft, insert the core, and apply air pressure. The adaptor expands and locks the core securely. Releasing air makes removal quick and easy, which helps reduce downtime during roll changes.
Overall, a multi bladder air adaptor is a flexible and practical solution for converters who want better machine utilization, uniform gripping, and quick size changeover without investing in multiple shafts.
