PRODUCTION OF COLLAPSIBLE POUCHES

The present invention relates to a production machine for the production of collapsible pouches, which comprises an impulse sealing device with a first jaw and a second jaw for contacting bottom regions of walls of the pouches. Each jaw comprises a susceptor element comprising electrically conductive material, having a front surface that is at least shaped as an inverted T for sealing side edges and at least a portion of bottom edges of two adjacent interconnected pouches. Each jaw comprises an inductor which is electrically insulated from the respective susceptor element. The machine comprises a high frequency electric current source, which is connected to the inductors. At least one of the jaws comprises a cooling device for cooling down the respective inductor and susceptor element. The machine is configured so that, in an impulse sealing cycle for sealing the bottom regions of the pouch walls, the electric current source is operated to temporarily feed a high frequency electric current to the inductors, thereby generating a high frequency electromagnetic field with the inductors. 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 impulses of heat seal the bottom regions of the pouch walls to each other.
