ABSTRACT:
Packs 12 of coffee or the like centrally disposed on a carton blank 11 are pushed down into the mouth of a holder compartment 53 by a ram sensing plate 33 under predetermined pressure, which folds up the side walls 16, 17 of the blank in a U-shape. Pivot arms 41, 42 disposed on opposite upper sides of the compartment and having vertically spaced embossing edges 38, 39 at their ends are then moved inwardly to crease the side walls at the height of the compressed packs in cooperation with sharp edges 34, 35 of the sensing plate. The latter is then withdrawn, whereafter horizontally movable folding tools 51, 52 move in laterally to bend down and overlap the upwardly extending coverwall tabs 19, 20.
