범퍼 빔은, 이 범퍼 빔이 본질적으로 수평한 분할 벽(14)에 의해 분리되는 2 개 이상의 폐쇄 챔버들(15, 16)을 가지는 일정한 횡단면을, 길이를 따라, 갖는 폐쇄된 횡단면을 가지도록, 롤 성형된다. 각각의 챔버는 차량으로부터 멀어지게 회전되는 측면(19) 및 차량을 향하는 일 측면(24)을 가지며, 이 때 하나 이상의 길이방향 오목한 부분(20, 21; 22, 23)은 전체 길이를 따라 연장하며, 이 때 하나 이상의 길이방향 볼록한 부분(25, 26; 27, 28)은 전체 길이를 따라 연장한다. 롤 성형 후에, 횡단면의 일부 부분들(32)이 변형 특성들을 적응하기 위해, 수직으로 또는 수평으로 함께 가압된다.

    A bumper beam is roll formed so that it gets a closed cross section with, along the length, constant cross section having at least two closed chambers (15, 16) separated by an essentially horizontal partition wall (14). Each chamber has a side (19), which is turned away from the vehicle, with at least one longitudinal concave portion (20, 21; 22, 23) extending along the entire length and one side (24), which is facing the vehicle, with at least one longitudinal convex portion (25, 26; 27, 28) extending along the entire length. After the roll forming, some portions (32) of the cross section are pressed together vertically or horizontally in order to adapt the deformation properties.
