ABSTRACT:
An apparatus for applying polymeric foam in-place to a surface comprising a movable framework which is spaced away from the surface and which forms a movable mold relative to the surface wherein a portion of the framework which is substantially parallel with the surface is comprised of a movable continuous belt located about a pressure plate being adjacent to the surface of the belt which forms a cover for the foamed surface. The continuous belt provides a non-blocking surface, i.e., one that does not hinder the movement of the framework as the foamed material rises and presses against the belt and pressure plate, since the continuous belt is rollably mounted.
