Process for the production of a cover unit with a seal for vehicle roofs and cover unit for vehicle roofs

Process for the production of a cover unit with a peripheral seal for vehicle roofs, comprising the steps of:

• A) providing a mold having a mold cavity having adjoining first and second mold spaces which open into each other;
• B) placing at least one cover part and a cover support in said mold with an edge area thereof extending into said first mold space;
• C) arranging a seal-receiving part, having an outwardly directed seal receptacle in which a resiliently compressible peripheral seal is mountable, in said first mold space at a distance from said cover part and said cover support so as to leave a connection-forming gap in the mold between them and the seal-receiving part, said seal-receiving part being positioned so as to isolate said second mold space from said first mold space and being oriented with said seal receptacle facing into said second mold space;
• D) closing the mold and introducing an elastomer into the mold so as to fill the connection-forming gap and connect the cover part and cover support into a unit with the seal-receiving part, the elastomer introduced being made of a softer material than the seal-receiving part and being prevented from entering into said second mold space by said seal-receiving part;
• wherein said seal-receiving part is positionally fixed so as not to be displaced during introduction of said elastomer;
• wherein said mold has upper and lower mold parts;
• and wherein said positional fixing of the seal-receiving part is produced by an attaching projection extending from each of said mold parts into the mold cavity at the junction of said first and second mold spaces, said seal-receiving part sealingly engaging against said attaching projections during introduction of said elastomer.
