Since many years dosing devices corresponding to the filling products with calibrated weighing systems have proved their function from the single scale up to the fully-automatically working packaging line. Especially developped automatic bag placers and low dust bag clamps guarantee maintenance-free filling and packaging lines, which are not harmful to the environment. The exact positioning and the re-folding of the filled bag at the spout are presuppositions for a trouble-free closing of the bag in downstream Greif-Velox bag closing systems. All kinds of closing as well as combinations are possible for multiply paper bags: welding, pin stop, sewing.
A new automatic supersonic closing system for open flat bags or gusset bags is presented for the first time at the exhibition, which replaces the conventional thermal welding procedures for open-mouth bags. Advantages of this system are welding cycles up to 2.500 units per hour. Contrary to the conventional thermal welding procedures the welding rim is capable of bearing immediately after welding, because the heat is immediately drained away over the system resp. the heat does not arise.
The Greif-Velox control is executed so that the mechanical parameters of bag size, bulk weights, etc. can be adjusted automatically by means of automatic selector switches or visualisations by PC.
The modular construction is trend-setting for the future. Automation is possible for every single station and they are expandable up to robot palletizing and pallet packages ready for dispatch.
