ABSTRACT:
Plastic foam insulation panels are fabricated in a continuous elongated strip by an apparatus comprising upper and lower generally horizontally extending conveyors which form a support for the foam material during the expansion and solidification thereof. The thickness of the panel is determined by the vertical spacing between adjacent runs of the respective conveyors and the panel width is determined by spaced apart longitudinally extending sideplates which, together with the upper and lower conveyor runs define the cross-sectional dimensions of the insulation panel. The sideplates are mounted on laterally extending arms secured to spaced apart support stanchions and the position of the respective sideplates may be adjusted to vary the width of the panel.
