Abstract
A process and device for manufacturing a section, in particular a hollow section, especially from light metal billets. To this end a plurality of billets is simultaneously forced through the shape-giving cross-section of a die and united to form the matrix metal for the section. For this purpose at least two bores in the container are aligned with the shape-giving cross-section of the die.
