Method for producing a seal, device for producing a seal and seal, in particular for sealing off a closing element of a motor vehicle

摘要

The method involves extending a seal (10) in a longitudinal direction. A foaming mass in a hollow chamber (18) is injected in a section of the seal along the longitudinal direction such that the foaming mass includes a variable pre-determined cross-sectional shape along the longitudinal direction. The hollow chamber is filled completely with the foaming mass in a transverse direction running perpendicular to the longitudinal direction. The seal is formed of thermoplastic elastomer. Independent claims are also included for the following: (1) a device for producing a seal of a motor vehicle (2) a seal for sealing a closure element of a motor vehicle.
