In the actuation of sealing jaws (12) for sealing of folding flaps of packages in conjunction with packaging machines, an active period of the sealing jaws independent of the working speed (rate of cycling) of the packaging machine is obtained by an actuating means (cam rocker 16), which is set off during each operating cycle of the packaging machine by a driving means with an accurately defined driving phase (stepping motor 23).
