Abstract
A compound sheet with a welded seam is arranged on a table (2) of the device (1). By lowering a cutting and bending punch (4), a cutout is cut from the compound sheet and bent downwards. A pulling device is arranged inside the device (1) underneath the table (2) to seize the downwardly bent cutout and tear it off the compound sheet. The quality of the weld can be evaluated by visual inspection of the appearance of the rupture point, in a known manner. In this way, tear test specimens of consistent quality and informativeness can be prepared very quickly and easily.
