The crankshaft 41 is released in practice, so that the next time the sheet metal is pre-cut, the main crankshaft, which also actuates the pivoting thrust of the seam strips, the scissor opening of the bar knife carrier 12.

Beim Rückgang sowohl des Messerträgers 12 als auch des Schwenkhebels 24 überholt das obere Quermesser 15 das obere Langmesser 13 wegen der erheblich größeren Exzentrizität des Exzenters 42 der Schrottmesser-Anordnung gegenüber dem nicht dargeslellten Exzenter des Besäummesser-Antriebes. Hierdurch gelangt das obere Quermesser 15 schnell in eine obere Totpunktlage, in der der an dem Blech 30 hängende Saumstreifen 31, obwohl er etwa in die Höhe des Bleches 30 zurückgefedert ist, nicht behindert ist.

When both the knife carrier 12 and the pivot lever 24 decrease the upper transverse knife 15 overtakes the upper long knife 13 because of the considerably greater eccentricity of the eccentric 42 of the scrap knife arrangement compared to the not shown eccentric of the trimming knife drive. This will get the upper one Cross knife 15 quickly in an upper dead center position, in which the hem strip 31 hanging on the sheet metal 30, although it is sprung back approximately to the level of the plate 30, it is not hindered. When a feed step is ended, the pivot lever 24 has already passed through its top dead center position and approaches the shown gate position.
