Removable Pocket Star Change Part

Customer Challenge

Customer wanted a more robust and cost-effective solution to their existing expensive crowner star assemblies for their high-speed, glass bottle packaging line.

Existing crowner star assemblies were causing declines in productivity and performance due to excessive wear, water absorption and glass damage.

About the Customer

Large multi-national brewery operating high speed bottling lines around the clock.


Septimatech developed a new ‘modular’ star design with a stainless steel skeleton and nylon pocket inserts that could be easily removed and changed in a couple minutes when damaged or worn.
