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.
