A machine and a method for folding bottom flaps of a box after or in coordination with box loading where all of the activities take place along one axis. The arrangement of all elements along the axis provides improved accessibility to facilitate clearing and servicing the machine. Precise indexing moves the boxes with a smooth cycling transfer motion from station to station in the machine as product in the box is supported and the bottom flaps of the box are folded under the product.
The folding of the box's bottom minor trailing flap is accomplished by a three piece mechanism which supports the product in the box and closes this flap.
The in-line arrangement permits easy adjustment of the machine for different size boxes. Threaded rods which are connected by chains, chain sprockets, unit rate gear boxes, half rate gear boxes, and shafts which move relevant operating elements to easily adjust the machine's box guide dimensions.
