ABSTRACT:
A stack of object is wrapped by first transversely outwardly stretching a tube having open ends and then pulling the transversely outwardly stretched tube over the stack to a position with the tube extending generally a full length of the stack and one open end of the tube projecting past an end of the stack. Then the tube is released such that it retracts into engagement with sides of the stack and the one open tube end bears on the end of the stack at least adjacent edges of the end of the stack.
