Abstract
Abstract Rectangularly shaped container are stacked within each other and advanced along a horizontal path through a treating station where changes are effected along two of the opposing sides of each container in the stack. The stack is then pivoted 90o in a special manner while remaining seated on the surface of a conveyor by means of an obstruction in the path of travel and a guiding surface mounted at an angle to the path, whereupon the stack is then advanced further in the same direction through another treating station to effect changes along the other two opposing sides of each container in the stack.
