When bending takes place, three stages are involved; there are the thirty, seventy five and ninety degree angles created. The structure of the surface remains undamaged. The machine is automatically adapted to take up different thicknesses of the sheets. The TRUMPF seam locker is made to lock Pittsburgh seams which are self powered and also silent rolled in the gliding process. The preparation of this type of locker is usually done by the use of a stationary machine. It then forms the required edges needed in the sheet metal part. In the end, a vertical seam part is always placed onto the Pittsburgh seam which allows two or even more work pieces to be joined together into one piece.
