Abstract: A mold has outer mold parts and inserted molding material cores. Together, the parts and cores form a mold cavity. The inner cores of molding material are arranged in several layers one above the other. The inner cores are clamped in between the outer mold parts and a final covering core of mold material. A continuous clamping force is applied between the parts and cores. The mold cavity is formed by surfaces of the outer mold, surfaces of the inner cores and the covering core.

Abstract: A rigid cover for a vehicle roof opening which includes a cover plate, a peripheral edge clearance sealing strip and a gap compensating element embedded in a plastic frame moulded around the circumference of the cover plate and supporting the sealing strip. The gap compensating element includes a deformation zone that can be permanently deformed in a transverse direction to increase a transverse dimension of the cover to fit the sealing strip against an edge of the roof opening. The outer edge area of the gap compensating element projects out of the plastic frame and has fixing elements for supporting the sealing strip on its outer edge. The gap compensating element can also be entirely embedded in a sealing strip attached to the plastics frame moulded onto the cover plate.
