摘要：
To produce an annular metal frame having an L shaped half-section for a lipped seal, a metal strip is cut into lengths, each of these lengths is rolled up circularly until its two ends are in abutment, so as to form a cylindrical ring (7), then this ring is driven into the cavity of small thickness defined between two parallel guide surfaces (S, S'), the entrance to said cavity having a shape complementary to that of the ring and the bottom of the cavity having a shape complementary to that of the frame to be produced.
