ABSTRACT:
A roller chute apparatus for packaging a flexible plastic bag filled with liquid in a box has four stacks of rotatably supported vertically spaced rollers. The four stacks extend a substantial depth into the box around the inside of the box sidewalls forming two pair of mutually opposing stacks. A first pair extends above the open top of the box and cooperates with the second pair in guiding the bag into the box. The second pair extends above the top of the box with opposing stacks being mutually spaced a greater distance than opposing sidewalls of the box, thereby forming a funnel-like opening with the first pair. A driver roller is substantially located above and adjacent to the top of the box forming an angular transition between each of the portions of the second pair extending above and below the top of the box.
