Abstract
A protective foam cushion-making apparatus dispenses reactive foam components into an interior space between two panels of plastic film to form protective foam cushions. The apparatus includes a supply of plastic film and a film driving assembly. A foam component dispensing assembly is interposed between the film panels and injects two reactive foam components into the interior space where they are mixed together to form a mass of expandable foam. The plastic film forms a flexible mixing chamber in the area between the two pliable rollers in which the reactive foam components are mixed together after they are dispensed from the foam dispensing assembly. The foam component dispensing assembly includes two foam component dispensing tubes that are oriented at an angle to each other. One of the dispensing tubes includes a diverter assembly attached to it that provides a reaction surface that directs the flow of one foam component into the flow of the other foam component.
