The star wheels are designed to eliminate changing the size within a certain bottle diameter range.
Instead of being characterised by the traditional pits, the size of which matches that of the bottle, such star wheels come with special grippers in highly shock-resistant non metallic material equipped with clamps which hold the bottle at three point locations, in this fashion they will always be positioned as compared to the original diameter of the star wheel.
When the bottle diameter varies, the grippers adjust although the “three contact points” remain the same.
In the case of very large diameter change in the package (exceeding 40 mm), the grippers, which are mounted on the star wheel with quickfit connections, are replaced.
This application may operate up to 60,000 BPH, and eliminates labor and downtime to change size.
