Abstract
A method for producing a trim strip comprising an extended portion (20) and a bent portion (19) which has a sharp edge (21) comprising the following steps: i) providing a blank with a material thickness and a shaped end cap contour (27); ii) bending the cap contour (27); iii) forming a sharp edge (21) along the bent portion (19), wherein a punch (31) for the edge-forming process, comprising a side surface (33, 37) which is stepped so as to correspond substantially to the material thickness and which faces the die (30) and counter die (32), is guided along the side surfaces (52, 35) of the counter die (32) and die (30) such that the step (34) of the punch (31) engages with the marginal edge (56) and displaces the material of the folded portion (19) towards the edge portion (21), thereby forming a sharp edge.
