Abstract
A method and machine for sealing at least one cut edge of a foam board is disclosed. The foam board has a top surface, a bottom surface and at least one cut edge extending between the top surface and the bottom surface. The cut edge is passed over a heated roller to soften the edge and then passed over a second roller having a temperature that is lower than the temperature of the first roller which seals the edge. The cut edge may be milled to square the edge relative to the top and bottom of the board before the cut edge is passed over the heated roller. Additional pairs of rollers may be provided to seal the top surface and the bottom surface of the foam board.
