Abstract
Articles, such as glass containers, are fed continuously in end-to-end relationship through a pin spacer adapted to provide a space between adjacent rows so that cross partitions can be fed therebetween. The articles are then grouped by a pin type grouper to provide predetermined members of article rows and columns in each group. The columns of articles are then spread slightly to allow longitudinal extending partitions to be fed between adjacent columns. At the same time flat tray blanks are withdrawn from a horizontally extending magazine and provided on a lug conveyor located below the path of the grouped articles and each blank is mated with a group of articles at a load station where the blank is formed around the articles by a pocket chain conveyor and article folding means operated in conjunction with an overhead flight bar conveyor which cooperates with the trailing portion of each pocket to fold all flaps provided on the tray blank.
