Identifying with a symbol or a reference mark has been the most frequent request which has motivated Nortan company to evolve its centring cards.
Now we are able to detect any colour without setting the photocell every time.
A brushless motor will position the bottle by centring the capsule mark with the folds.
For the White & Mackay company, Nortan is using the new UV ray photocell that is able to detect a particular background that is invisible to the human eye and therefore able to decorate the entire capsule circumference.
Furthermore, several machines for small and large productions have been made with the possibility to centre the symbol on the bottle with the capsule brand.
