Claim Text:
1. A method for applying a sealing compound to a surface, wherein a ring-shaped structure is formed from a plasticized sealing compound and subsequently deposited on the surface, wherein: the plasticized sealing compound is annularly brought into a temperature-controlled annular gap having a variable gap width, said annular gap being disposed between an inner stamp and an outer stamp, said inner stamp having a lower flange and said outer stamp having a lower surface, said lower surface being constructed and arranged to mate with said lower flange, the sealing compound is completely squeezed out of the annular gap by fast reduction of the annular gap width to zero, and is formed to the ring-shaped structure and laid down on the surface thereafter, wherein the annular gap width is reduced with such a great velocity and the sealing compound is squeezed out with such a high velocity that any adherence of the melt on gap edges, as well as on surfaces neighboring to the annular gap, is avoided.
