Abstract: 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.

Abstract: A sealing system for heat sealing superimposed walls of heat-sealable film material, e.g. in the production of pouches. The sealing section comprises two or more sealing stations arranged in series along a linear path for the superimposed walls dispensed from an infeed section. Each sealing station comprises a sealing device with first and second jaws and an actuator device to move the jaws between an opened position and a clamped position. Each sealing device comprises a motion device that is configured to move the first and second jaws in synchronicity with the superimposed walls when clamped between the first and second jaws. Each sealing station has a cooling device that is configured to continuously cool at least one of the jaws. At least each first jaw comprises at the respective front surface thereof at least one impulse heatable member embodied as a susceptor element that extends along the respective front surface.

Abstract: A pouch handling machine comprises and a series of pouch related process stations. A reciprocating beams conveyor advances pouches intermittently along the stations. The conveyor comprises a left-hand side and a right-hand side elongated reciprocating beams, each provided along the length thereof with pouch retention members. A left-hand side and a right-hand side support member, each support reciprocating beams and form a linear guide of the reciprocating beams. A left-hand side and a right-hand side electromagnetic linear actuator are provided, each being mounted between the respective reciprocating beams and the respective support member to cause an intermittent reciprocating motion of the reciprocating beams in the longitudinal direction thereof. These actuators are linked to an electronic controller that is adapted to synchronize the motions of the actuators.

Abstract: The invention relates to a method for producing flexible containers comprising a dispensing valve, said method including: vertically forming a tubular body (2) by means of vertically displacing and longitudinally folding a heat-sealable film (1); longitudinally welding two vertical ends (11, 12) of the heat-sealable film (1); producing, from the tubular body (2), independent flexible envelopes (3) provided with a closed bottom and an open upper mouth (33), by means of carrying out successive transverse weldings (32) and transverse cuts in said tubular body; and horizontally moving the successive flexible envelopes (3) through a series of working stations wherein the product to be packaged is dosed, a dispensing valve (4) is placed in the upper mouth (33) of the flexible containers (3), and the upper mouth (33) is welded (34), securing the dispensing valve (4).
