In a method for manufacturing blown film web on a blown film line, film is heated above the takeoff device and then treated mechanically. This allows the film to be brought from initial heat to an easy-to-process temperature level with little energy. A horizontally oriented treatment roll path is provided between the takeoff and a reversing device is arranged above the takeoff. In both aspects, controlling is performed to achieve a uniform film gauge after stretching. |
