Abstract
Curved laminated sandwich panels having a plastic foam core and surface skins are prepared by applying pressure sensitive adhesive to at least one of adjacent faces to be joined, interposing a slip sheet between adjacent surfaces of the sheets to be laminated, positioning the sheets to be laminated within a matched die mold, removing the slip sheets and passing the matched die mold through pressure rolls to deform the sheets and conform them to the shape of the mold.
