Abstract:
A method of combining groups of articles to form packaging units includes wrapping a packaging unit along a running direction thereof on a transporting path with a sheet material, concurrently with the wrapping, forming a sheet-material overlap and folding flaps that each project beyond the packaging unit along transverse peripheries thereof, positioning the folding flaps against the packaging unit as the packaging unit passes through a folding unit, and fixing the folding flaps to each other, thereby forming a sheet-material wrapper that is closed on all sides.
