ABSTRACT:
An apparatus for joining and folding container sections to form a hinged container. Two container sections are transported in end-to-end relation on a conveyor and the downstream section is engaged with a stop while a pusher member is pivoted into engagement with the trailing edge of the upstream section to force the sections together and engage snap fitted hinge elements on the two sections. The hinged container is then discharged from the first conveyor onto a second conveyor located at a level beneath the first conveyor and operating at a slower speed than the first conveyor. As the leading section of the hinged container falls from the upper conveyor onto the lower conveyor the increased speed of the upper conveyor will fold the trailing section over the leading section to provide a closed hinged container. The closed container then passes under a spring loaded pressure member which ensures that locking elements on the two container sections are fully engaged.
