ABSTRACT:
In order to wrap dishes filled with fruit, meat or vegetables with a thin stretchable foil, a group of grippers carried on spaced endless chains are arranged to clamp the foil edges. The grippers are held in their foil gripping position each by a presser plate. The grippers transport the foil and hold it while the goods are raised thereagainst, stretching the foil. A cutter cuts off a foil section. It is situated in such a position that the severing operation is carried out at a position while the two foil edges are held fast by the grippers, thus facilitating the drawing forward of a foil, unwound from a supply roll.
