ABSTRACT:
The invention relates to a method of manufacturing shell-shaped packages, in particular flower sleeves, in which two superposed bands of synthetic material are supplied and machined through die cutting, in such a manner that at least one edge of each package, defining the wide opening, is formed along an ornamental line, whereafter the material bands are cut in transverse direction into separate package portions, the discrete package portions being joined together at the cut edges so as to form the package, wherein, during the die cutting of the longitudinal edges of the material bands, both material bands are perforated through and through in one die cutting operation so as to form suspension portions joined to the package portions via perforated lines extending along an ornamental contour, the suspension portion, formed by the perforation, of one of the two material bands being removed. The invention further relates to an apparatus for carrying out the method, and to the package obtained by the method.
