Abstract

The tool, in particular for making a horizontal fold in bending the rim of a metal foil (1) through 180 DEG around the edge of a thin sheet (14), is characterized by a holding element (21) of U-shaped cross-section, between the arms (22, 23) of which a strip of elastomeric material (24) is laid. During folding of the foil (16) the elastomeric material (24) conforms the foil closely to the edge contour of the thin sheet. For a contoured rim around a workplace e.g. a heat shield between a catalytic converter and a car cabin, a series of such tools are provided.
