ABSTRACT:
An object having a top and sides is wrapped by first covering it with a hood-shaped foil such that excess-foil projections are formed that project from the top of the object past the sides of the object. Then the foil is pulled adjacent the projections out of contact with the object to form an empty space adjacent each projection between the foil and the object. The excess-foil projections are then tucked into the respective empty spaces, normally on the sides of the object.
