A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.

A compression load distributor includes a support layer and a heat spreading layer. The support layer includes a flexible carrier configured to distribute a load from a compression load applying device. The heat spreading layer is coupled to and carried on the support layer, the heat spreading layer comprising a heat sink configured to transfer heat throughout the compression load distributor. The heat sink is thermally conductive and electrically non-conductive.

An impulse welding bar (10) for welding plastics films is provided with a detachable non-stick coating (20) which is held on lateral flanks (24) of the impulse welding bar (10). In order to facilitate the replacement of a worn non-stick coating (20), retaining elements (22) are provided which are made of two or more parts and which act in a form-fitting manner in order to detachably fasten the non-stick coating (20) to both flanks (24) of the impulse welding bar (10), wherein first parts (26) of the retaining elements (22) are arranged on the flanks (24) of the impulse welding bar (10) and second parts (36) of the retaining elements (22) are arranged on the non-stick coating (20).

An assembly to connect together first and second sheet members. The assembly includes a pressure device that applies pressure to the sheet members while the sheet members are in an overlapping arrangement and positioned on a support platform. A sensing system that includes one or more thin film pressure sensors detects the positions of the leading and trailing edges. A connection device connects the members together in an overlapping arrangement.

A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.

A machine includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement provides air at a first pressure to inflate a first web of a first type of inflatable material, provides air at a second pressure to inflate a second web of a second type of inflatable material, receives the first and second webs, and aligns the first and second webs on the machine. The first pressure is different from the second pressure. The sealing arrangement seals the first and second types of inflatable material. The tensioning device provides a first tensioning force to the first web as the first web moves between the inflation and sealing arrangements and provides a second tensioning force to the second web as the second web moves between the inflation and sealing arrangements. The first tensioning force is different from the second tensioning force.

A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

A tooling for use in a method for electromagnetic welding of two contacted surfaces of molded parts. The tooling includes a rubber body and pressurizing means for pressurizing the rubber body and applying pressure to the contacted surfaces. The rubber body includes an embedded stiff body shaped such as to define different rubber body thicknesses in different directions, which causes a different pressure build-up in the different directions. A method for manufacturing the tooling. The tooling may be used in electromagnetic welding of two contacted surfaces of molded parts by moving a joining inductor along the contacted surfaces, generating an electromagnetic field in an induction-sensitive component of the molded parts to heat a thermally activated coupling means of the molded parts to above a melting temperature of the coupling means.

The invention is directed to a thermoforming packaging machine (1) for producing sealed packages (2) having a planar surface (3) and a shaped recess (4) comprising a sealing station (6) with a lower sealing tool (7) comprising of a first part (8) provided with a first seal seam support (8a) for supporting a first sealed seam (9) at the outer perimeter (10) of the planar surface (3) of the moulded product (2a) and a second part (11) provided with a second support (11a) provided with a seal seam support opening (12). The second support (11a) supports a second sealed seam (12a) on the planar surface (3) of the moulded product (2a) following the perimeter (13) of the shaped recess (4). The first part (8) and the second part (11) are separate parts which are detachable connected.

An impulse welding bar (10) for welding plastics films is provided with a detachable non-stick coating (20) which is held on lateral flanks (24) of the impulse welding bar (10). In order to facilitate the replacement of a worn non-stick coating (20), retaining elements (22) are provided which are made of two or more parts and which act in a form-fitting manner in order to detachably fasten the non-stick coating (20) to both flanks (24) of the impulse welding bar (10), wherein first parts (26) of the retaining elements (22) are arranged on the flanks (24) of the impulse welding bar (10) and second parts (36) of the retaining elements (22) are arranged on the non-stick coating (20).
