Abstract: A method and apparatus for packaging flat or stacked cylindrical article groups into a packaging unit such as a paperboard carton wherein at least one stream of cylindrical articles are conveyed single file in parallel lanes into a staging area where the lanes terminate, thereby directing the articles into a closest packing formation. Articles are moved in closest packing formation through the staging area over a deadplate toward one of a plurality of containers moving in a generally linear direction parallel to a carton line. An angle of approximately 60.degree. between the staging area and a container in position for receiving articles orients a row of articles in closest packing formation parallel with the open front end of that container. As articles enter the container, each row of articles rolls over the previous row, causing articles to be arranged in a rectangular array in the container.

Abstract: An apparatus for controlling the input of articles at the start-up phase of a packaging machine of the type having at least one article conveyance lane and an article grouping mechanism constructed and arranged to meter articles moving in the conveyance lane into predetermined groups, comprising:(a) at least one stop post aligned for extension into the conveyance lane, the stop post further being disposed at an infeed end of the article grouping mechanism;(b) means to actuate the stop post, whereby the stop post is extendible and retractable in the article conveyance lane, the stop post impeding travel of articles in the lane when extended and permitting travel of articles in the lane when retracted; and(c) means to coordinate actuation of the means to actuate with operation of the article grouping mechanism.
