The device has an area with variable cross-section and a unit for changing the area of variable cross-section (1). The coiled flat material (2) forms a closed volume, which is wound at two loops (3,4). The former loop is partially wound to guide and form plastic profile. Two guide rod pairs are arranged at the latter loop. An independent claim is also included for a method for guiding and forming the plastic profiles, particularly plastic pipes. |
