Abstract: Described are a machine and a method for forming containers from blanks, including a plurality of shaping hoppers, an endless conveyor which defines a feed path and on which the hoppers are mounted in succession and a plurality of pushing elements which are movable in such a way as to follow the respective shaping hoppers along at least a stretch of the feed path and which have a to-and-fro operating movement towards and away from the respective hopper along a direction transverse, preferably perpendicular, to the feed path. The machine also includes folding means disposed along the feed path downstream of the pushing elements and configured to produce, respectively, a top closure and/or a bottom closure of the tubular blank.

Abstract: A device for feeding charges of non-homogeneous infusion material to a packaging machine includes a metering device for the charges and transfer system for the charges which is positioned downstream of the metering device and which feeds the charges to the packaging machine. The transfer system includes a charge adjustment system equipped with a drum which is rotatable about its own axis A and at least one roller which is rotatable about its own axis B and which is located upstream of the drum. The drum includes a chamber for receiving the charge from the roller. During adjustment of the charge, the chamber is variable between a maximum value coinciding with the receiving step and a minimum value when the charge has been adjusted.
