Abstract
An automatic packaging machine can load light and fluffy particulate product without having it scattered over a large area. The system does this by using a plurality of inclined planes to cause said product to slide in successive small steps, as distinguished from simply dropping in a single fall. The system also tips a box and provides a vent to prevent air from being entrapped and compressed within a box as it is being filled.
