ABSTRACT:
A process for the production of a cover unit with a seal for vehicle roofs in which a cover part, such as a glass cover part, a cover support and a profile part, having a replacement seal receptacle are inserted in a mold having an upper part and a lower part. The profile part is spaced from the cover part and the support leaving edge gaps which are filled by introducing an elastomer therein to connect this assembly to a cover unit. The profile part is attached and aligned, in a preferred embodiment, by attaching projections on the upper part and/or lower part of the mold depending on its position in the production of the cover unit. A peripheral seal can be molded on the profile part.
This peripheral seal can be removed from the profile part, so that the seal receptacle of the profile part can be used to insert a replacement seal. Also, a resulting cover unit for vehicle roofs comprises a cover part, a cover support and a profile part with a replacement seal receptacle and an, optionally, molded-on peripheral seal. The cover part and cover support are connected to the profile part by an elastomer to form a cover unit.
