Krones subsidiary Kosme, Roverbella, has unveiled an innovative concept of a block configuration available in two different variants, for PET and for HDPE containers.

The 3Bloc for PET comprises three concatenated machines: blow-moulder, filler and labeller. The particular version of the Flexa labeller can vary, either featuring pressure-sensitive labelling with a Flexa Sensicol station or wrap-around labelling with a roll-feed capability. This version is suitable both for cylindrical and square PET bottles and also for containers with special shapes. The maximum speed is 16,000 bottles per hour.

In the case of HDPE containers, the blow-moulder is replaced by an unscrambler for erecting them as they are fed in. This 3Bloc variant is able to handle up to 25,000 bottles per hour.

A spokesperson for Krones said: “The 3Bloc’s technically sound design concept scores particularly well with its significantly reduced energy consumption compared to individual machines, and also with its higher efficiency and enhanced operator-friendliness, thanks to the Human Machine Interface (HMI). The block configuration, likewise, benefits the footprint of the machinery layout, plus the capital investment and operating costs. For example, intermediate conveyors are no longer needed, and the times required for changeovers and maintenance work are shortened as well.”
