Abstract: The assembly performs the method of handling packages having a panel extending outwardly from one side of the package and along one edge thereof. A plurality of such contiguously nested packages is provided with the extending panel of each package disposed in the same direction and overlapping the side of the next adjacent juxtaposed package. The end package of the plurality of nested packages has its extending panel directed outwardly from the plurality and is rotated to cause the extending panel thereof to be placed in an overlapping relationship with respect to the next adjacent juxtaposed package. The plurality of packages being fed to the work station of the end package rotation process is acted upon in a particular manner to cause them to shift with respect to each other to produce a substantially uniform overlapping disposition of the outwardly extending panels with respect to the side of the next adjacent juxtaposed panel.
