Abstract (en)
[origin: EP0091176A1] A method of and apparatus for extruding material, such as aluminium. The material (4) to be extruded is supplied in commercial sizes, reduced to a pre-determined length to form a billet (7, 7 min , 7 sec ), which is placed in a heating container (3), in which a ram (2) is operative to press the material present in the container (3) through a die (9) provided with at least one extrusion orifice to form extruded mouldings (10). The mouldings (10) are discharged by means of a discharge device (11). According to the invention the weight per unit length of the extruded moulding (10) is determined at least once during the extrusion of each billet (7, 7 min , 7 sec ).
