Method for the production of sheet-metal parts provided with punched-out tabs

Verfahren zum Herstellen von mit ausgestanzten Laschen versehenen Blechteilen


The roller punch has two rollers (16, 17) between which a sheet-metal material passes. On the rollers there are tools (19, 21) which produce a U-shaped cutting line (30) and a bending line (31). A tab (29) is thereby formed from the sheet-metal material in a single operation. This tab can be provided during its production with projections (32, 33). <IMAGE>
