Claim 14:
15. Method for the production of collapsible pouches, wherein use is made of a production machine according to claim 1, the method comprising the steps of:
bringing the first and second jaws into the clamped position with the actuator device, so that—in the bottom regions—the first and second walls are clamped against one another by the front surfaces of the first and second jaws,
in the clamped position, operating the electric current source to temporarily feed a high frequency electric current to the one or more inductors, thereby generating a high frequency electromagnetic field with the one or more inductors, wherein the high frequency electromagnetic field induces eddy currents in the respective susceptor element generating an impulse of heat that is emitted by the susceptor element, which one or more impulses of heat seal the bottom regions of the pouches,
establishing a continuous circulation of liquid coolant through the one or more cooling ducts, to cool down the first and second jaws, at least the one or more impulse heatable members thereof, after termination of the energizing assisted, and
moving the first and second jaws into the opened position with the actuator device after the one or more impulse heatable members have cooled down.
