Abstract
An improved vertically oriented machine which is capable of forming and adhering lids to open ended fiberboard containers. The improved machine includes a lower horizontal conveyor for bringing open-ended containers into the machine; a vertical lifting section including a novel elevation mechanism for lifting the containers; a lid feeding mechanism located along the path of the vertical lifting section for providing the lids to be placed onto the containers; a set of adhesive applicators; a series of adjustable spring-mounted compression shoes including a novel frictional lid holding member located along the path of the vertical lifting section above the lid feeding mechanism for deforming the sides of the lids around the container; and an ejection mechanism for removing the lidded container from the machine.
