Abstract
A molten disc (17) is applied to seal the end of a tubular element (1) and, while the disc is still in a moldable state, it is formed into a head using either a fluid pressure, a vacuum, or both on opposite sides. A sealing head (37) on an internal sealing mandrel (35) has a first shoulder (39) thereabout which is complementary with a second shoulder (73) about a mold cavity, which trap the periphery of the disc, and the head is formed in a configuration conforming to the mold cavity by fluid pressure injected through the internal sealing mandrel, through a vacuum pulled through the mold form containing the cavity, or by use of both said fluid pressure and said vacuum. <IMAGE>
