When manufacturers started demanding even higher output and speed, the company went on to the next level for further development of the system. The objective was to achieve filling performances of minimum 2,000 bags per hour for bag weights of five to 50 kilograms, making the machine attractive for mass-oriented markets and companies. Up to this point, the multispout machine had operated in intermittent mode. The new continuous operation was able to increase performance from 1,200 to more than 2,000 bags per hour. Based on components from the rotating packaging machine, Haver Roto-Packer, the engineers developed a new filling module with gross weighing for shorter filling times. The bag handling modules that place and remove the PE bags on the new filling spouts are also new. The rotating modules have two gripper units each, which ensure highly accurate transfer.

Air or turbine units can be used as filling modules. The combined control and weighing electronics MEC, an in-house development, provided for exact filling quantities; internal and external vibrating units ensured the required product compaction. Thanks to micro-vibration, the air bubbles inside the product automatically move to the top. The main advantage of this mechanical procedure is its very high availability. In contrast to vacuum systems, micro-vibration does not suck off any fine particles. The filled bags are safely sealed in low-maintenance pulse welding stations and then transported to the bag forming section.


If required, a head seam cleaning and cooling system can easily be integrated. The modular configuration of the Haver Adams makes it possible to use between one and twelve filling spouts. This significantly increases the circle of applications. All products that are filled in valve bags and have a minimum bulk density can now also be filled in PE bags.

Service has Top Priority

Apart from high performance, ease of operation and noise protection range amongst the key features of modern filling systems. The complete enclosure of the system keeps noise development at a low level, leading to high noise insulation as well as significantly reducing dust. Thanks to the Haver Service Pad (HSP), remote support is accessible at the push of a button. The system, consisting of a touchpad, integrated camera and software, enables operators, service technicians and specialist workers to directly communicate via a high-speed Internet connection. The result is short reaction times and higher machine availability.


At present, almost 60 such machines from the company are used all over the world. And recently, it has found its use in a titanium dioxide filling plant. The filling system offers optimum product protection and extended storage times, even in case of adverse weather conditions. The machine delivers resilient packaging and a clean logistics chain in all fields of application. With its compact dimensions, it is suited for all production environments. For the chemical industry this means an entirely new, yet well-tried process FFS filling of powder-type products and products with challenging flow properties into PE bags.
