Abstract

The invention relates to a method for forming package bodies open at one end from package sleeves open at both ends for the manufacture of filled packages. In order to allow packages with a cross section which is neither square nor rectangular to be formed more simply and reliably, the package sleeves are kept ready for further processing in a stack, folded flat along at least two folded edges running in the longitudinal direction of the package sleeve, the flat-folded package sleeves are transferred in succession from the stack to a forming station, the package sleeves are unfolded in a forming station and the unfolded package sleeves are, in the forming station, pushed onto a mandrel in order to close, in particular seal, a longitudinal end of the package sleeve.
