ABSTRACT:
The invention relates to a profile for a seal comprising a metal reinforcement having a U-shaped cross-section. The reinforcement is sheathed with plastic. At least one virtually inextensible filament is embedded in the plastic in an intermediate zone between the profile and an associated sealing element in the region of the median fiber of the profile. According to the invention, the metal reinforcement is formed by bending a planar reinforcement into the shape of a U. The planar reinforcement comprises a succession of exposed rectangular elements having long sides perpendicular to the plane of symmetry of the U and short sides parallel to this plane of symmetry. The rectangular elements are joined to the contiguous elements by two spacers parallel to the plane of symmetry of the U.
