摘要

The device for producing one or more extruded profiles with variable cross-sections in the press direction comprises a holed press bar (5) with an axially displaceably mandrel (11) with varying cross-sections (13) in the end area (12), functioning with a press plunger (3), a press plate (4) and au upper part (7) of a chamber tool as far as the area of a shaping matrix (8). The end area of the mandrel extends into the matrix (8), leaving free a ring gap (14).
