Abstract
A cylinder head cover for a combustion engine having a cover member (2) and a seal (4) made of an elastomer, which includes a metallic stiffener (8) and which serves for sealing with respect to the cover member (2) and a cylinder head surface (12) is characterized in that the cover member (2) is made of plastics and that the cover member (2) and the seal (4) are joined to a prefabricated unit after a corona treatment of the surface (5) of the seal (4) opposite the cover member (2) and adhesion by means of an adhesive.

A method for manufacturing a cylinder head cover for a combustion engine having a cover member (2) and a seal (4) made of an elastomer (6), which includes a stiffener (8) and which serves for sealing with respect to a cylinder head surface (12), characterized by
- forming the cover member (2) of plastics,
- activating a surface (5) of the seal (4) opposite the cover member by corona treatment,
- applying an adhesive (7) onto the activated surface (5) of the seal and/or onto a counter surface (16) of the cover member (2),
- inserting the cover member (2) and the seal (4) into a heatable, preheated adhesion apparatus,
- holding the adhesion apparatus in closed condition for a predetermined period of time at a predetermined temperature and
- removing the ready cylinder head cover from the adhesion apparatus.
