u The packaging machine has a cachet device with a cover foil (1) that is connectable to a court (2a) with a base foil (2) beneath a heat supply and pressure operation. The cachet device has an automatic feed roller (3) with a cachet roller (4) opposite it and between which the foils (1, 2) are located such that they are transportable perpendicular to the roller axis. The pressure operation achieved is dependent on the foil position which may be specified by means of a rotary position transducer (6). There may be an element (7, 8) provided to exert a variable force on the automatic feed roller. There may be a storage element in which the course of the pressure impacts is contained. There may be an electro-motor element (6) with a force regulator that operates as an overload protector for the cachet roller against foreign bodies.
