发明名称 METHOD FOR BENDING A COMPOSITE SHEET AND SUCH A BENT COMPOSITE SHEET
摘要 The invention relates to a method for bending at least one edge of a composite sheet, which has at least two outer metallic layers and an inner plastic layer, in which the edge of the composite sheet is edge-bent in a first step and is bent into the finished form in at least one further method step. In addition, the invention relates to a correspondingly bent composite sheet. The object of making a method for bending a composite sheet available, in which cracks in the metallic layers of the composite sheet can be prevented and, at the same time, in which a seam can easily be provided, is achieved by using an edge-bending punch, a holding-down device and an edge-bending jaw during the edge-bending operation and by the edge-bending punch having a notch running in the bending direction below the bending edge of the edge-bending punch.
