The sidewall surrounds a cavity and includes a border defining externally a cutting edge. A die support is provided such as to have a lower side substantially adhering to the upper side of the web and having an opening aligned with and complementary to the punching member, such as to permit the insertion thereof through the opening and the punching out of one package from the web during the raising movement of the punching member from the lowered position to the raised position. A second stem is slidably guided parallel to the first stem and is provided at the top with a plate receivable in the cavity. The stem is driven between a position wherein the plate underlies the web and a position wherein the plate overlies the web after the package punching has been completed. A stacking magazine is provided for the raised packages. The stacking magazine is located above the die and is inclusive of a retaining means such that for each raised package there occurs a raising of the packages previously introduced in the magazine and the resting of the package last introduced on the retaining means.</p> |
