ABSTRACT Apparatus is disclosed for cutting stacks of flat workpieces, particularly of making undershirt-shaped bags from stacked tubular film sections made of thermo- plastic material and formed with side gussets and with top and bottom end seam welds. The apparatus comprises a group of punch-and-die sets, which are mounted in a machine frame and include punches associated with drive means for moving said punches up and down, and die plates, which are fixed to the machine frame, and also comprises a conveyor for intermittently feeding the stacks between and for removing them from the punches and dies. At least two punch-and-die sets and the drive means associated with them are arranged in a row in a carriage, which is guided for reciprocation in the machine frame in a direction which is transverse to the direction of travel of the stacks, and said carriage is adapted to be arrested in the machine frame in two operating positions, in each of which at least one of the punch-and-die sets protrudes laterally from the machine frame.
