Abstract:
Process for the manufacture of a cover unit of a vehicle roof, which can be opened, and which has a cover plate, a reinforcing frame arranged therebelow, and a rigid seal-receiving frame injection molded around an outer periphery of the cover plate and reinforcing frame, the seal-receiving frame having an encircling groove on an outer periphery thereof for receiving a resiliently deformable peripheral seal, comprising the steps of:a. placing the cover plate onto the reinforcing frame and placing the cover plate and the reinforcing frame into the center of a mold so that the mold peripherally surrounds the reinforcing frame and cover plate at a distance therefrom;b. inserting said resiliently deformable peripheral seal into the mold so that an encircling edge gap sealing profile of the seal extends along an inner edge of the mold while leaving an interspace between peripheral seal and both the cover plate and reinforcing frame;c. closing the mold and injecting a synthetic plastic material into the interspace so as to mold the rigid seal-receiving frame connecting the cover plate and reinforcing frame and simultaneously forming said encircling groove in the seal-receiving frame by surrounding an inwardly directed part of the peripheral seal with said plastic material and using said inwardly directed part as a core for directly forming said encircling groove in the seal-receiving frame; andd. opening the mold and removing a finished cover unit.
