    Abstract: The invention relates to a method for extruding a profile or a similar billet (50) from a bolt or bar (30, 30a) that is guided in a recipient bore (16) of a recipient (14) and that is extruded by means of an extrusion die (10) through a shaping section (46) of a shaping tool (38). Once the front face (34a) of the bar (30) is placed on the rear surface (33a) of a preceding bar (30a), air or similar flowing agents present on said surfaces (33a, 34a) are discharged during pressure build-up in an approximately radial relation together with the contaminations that are present in detached form on the transversal bur surface. During pressure build-up, parts of the transversal burs are radially displaced; the displaced parts of the transversal bur surface are discharged on the periphery in an approximately radial relation before the bar enters the shaping tool (38). To achieve this, a welding chamber or pre-chamber (70) is disposed in the direction of extrusion (x) in a gap that can be adjusted between the recipient (14) and the shaping tool (38). Said chamber is provided with at least one lateral opening or discharge channel (72) through which the displaced parts of the transversal bur are discharged.
