The second generation of the most famous Acmi patent has been further improved both in terms of the programming as well as mechanical aspects. The numerous Twisterbox machines in function along with the new production and new format requests have contributed in increasing the Acmi know how in the projection and construction of the layer formation systems. When there is an idea that works, just like the Twisterbox, and it is coupled with continuous research and development of the product it is possible to supply a punctual reply to the requests of the customers. This is the reason that the Twisterbox layer formation system patented in 2002 has no rivals.

THE GRIPPING SYSTEM

As far as the selecting pliers which are the keystone of the system are concerned, Acmi has recently introduced the use of carbon. This innovation has allowed for an improved lightness in construction along with improved resistance and less overall space required for the pliers. Thanks to these characteristics the new pliers are capable of moving at a faster speed, improving the overall output of the entire machine.  Another characteristic of the second generation model is the opening and closing movement of the pliers that has changed from being asymmetrical to concentric improving the precision during the gripping phase.  Furthermore, the movement of the opening and closing may be continuous or in more than one phase in order to allow the pliers to pass with improved agility amongst the flow of packs to be palletised. Thanks to the new pliers the number of format changeovers is also reduced as the pliers are capable of handling more than one format at the same time. The Twisterbox can manipulate any type of container with any content maintaining high speeds. An example of this at the Heineken UK plant where two second generation Twisterbox machines handle 3x2 multipacks with a speed of 120.000 cans/hr each, even without over packaging.
