Method and Device for Forming Package Bodies Open on One Side from Package Sleeves Open on Both Sides

Abstract

Described and depicted is a method for forming package bodies open on one side from package sleeves open on both sides for the manufacture of filled packages, in which the package sleeves are folded flat and held ready for further processing in a stack around at least two folding edges running in the longitudinal direction of the package sleeves, in which the flat-folded package sleeves are transferred successively from the stack to a forming station, in which the package sleeves are unfolded in the forming station, in which the package sleeves are pulled in the forming station through a channel coming into contact with the two opposite folding edges of the package sleeve and tapering transversely to the package sleeve and/or the package sleeves are positioned in the forming station between at least two form halves of a form and unfolded by closing the form, and in which the unfolded package sleeves are slid from the forming station onto a mandrel for closing, in particular sealing, a longitudinal end of the package sleeve.
