Method and apparatus for forming the profile of deformable materials and deformable tubular sections

摘要

An apparatus for forming the profile of deformable materials including tubular sections. The apparatus (1) includes at least two sets (4, 5) of die elements (6), each set (4,5) including a plurality of die elements (6) respectively arranged to travel along corresponding endless path. The paths each include a forming portion (9,10) in which die elements (6) of each set (4. 5) are opposed to define a forming space (11) therebetween. The forming portion (9, 10) of each path is configured so that one or more dimensions of the forming space (11) reduce along the length of the forming portion (9,10) to simultaneously apply lateral forces to material progressing through the forming portion.
