Abstract:
A laminating machine and the method incorporated therein includes a pair of opposing and substantially parallel cylindrical steel rollers defining a continuous pressure line between the outer cylindrical surfaces thereof. A sheet is fed between the rollers in a first direction substantially transverse to the pressure line, and a film to be laminated is fed onto the sheet surface and with the sheet in the first direction. A fluid pressure cylinder-lever arm arrangement is provided with one of the rollers for applying relative pressure between the two rollers along the pressure line during passage of the film-sheet combination therebetween, the pressure being in an amount sufficient to compress the sheet to effect complete bonding of the film to the sheet surface, but in an amount less than that which causes structural damage to the sheet. The outer surface of one of the rollers is heated during the laminating process.
