Sheet material to be laminated to a substructure is presented in a stretched out condition for enclosing between upper and lower laminating tools. For this purpose a sheet material transport mechanism such as a tentering frame is movable back and forth between the laminating station and a sheet receiving position. The sheet margins around outer and inner edges of the laminated work piece are then trimmed and bent over inwardly. These operations are performed while keeping the work piece on the same lower tool or mold during all operations. The lower tools are moved from laminating to trimming and vice versa on a turntable.
