Substantially tubular, or sleeve-type, cartons each with an end opening
having a width less than a pitch of flight bars of a packaging machine but
having a combined end opening equal to the pitch of the packaging machine
are erected and placed between the flight bars. In one embodiment, the
cartons are detachable affixed to one another. In another embodiment, the
cartons are detachable affixed to one another in collapsed condition such
that the composite collapsed carton formed thereby has dimensions
substantially similar to a single carton loadable on the machine.
