Abstract
Bending a laminate having a thermo-plastic core layer and metal sheets adjoining the core layer on both sides, is performed by heating the laminate and then bending it. To allow bends of small radius to be made, heating causes softening of at least one of the boundary regions of the core layer adjoining the metal sheets, while a central region of the core layer remains unsoftened. The heat may be by inductive heating of one or both metal sheets.
