Method for manufacturing e.g. prefabricated sheet that is processed to attachment for steel body of commercial vehicle, involves folding steel sheet along bending edge outside overlapping region so that edge adjoins at overlapping region
摘要
<p>The method involves roll bonding a steel sheet (3) with an aluminum sheet (4) in an overlapping region (5). The steel sheet is folded along a bending edge outside the overlapping region so that the bending edge adjoins at the overlapping region. The steel sheet is roll bonded with another aluminum sheet (7) in another overlapping region (8). The steel sheet is folded along a second bending edge outside the both overlapping regions. One of the aluminum sheets is folded along third bending edge outside the both overlapping regions.</p>
