A sealing element for sealing a package, the sealing element being configured for cooperation with an abutment for engaging the package for providing a seal to the package and a device for sealing a package, the sealing element includes a sealing element, an abutment and a base, wherein the sealing element is releasably supported by the base, and wherein at least one of the base and the abutment is moveably arranged for engagement with the package from opposing sides for providing a seal to the package.

The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.

An inventive through transmission connecting device for connecting a first component made of a light absorbing material to a second component made of a light transmissive material by means of a light transmission bonding technology. The connecting device includes a first tool mounted to a first support retaining the first component and a second tool mounted to a second support retaining the second component. The first tool and the second tool are movable with respect to each other and the first tool is at least partly made of or includes a layer of a thermal isolator having a high thermal resistance.

Multi-layered articles or products comprising layers of filled polymer compositions, methods of making and applications or uses thereof.

A heating block assembly including one or more configurable insulator segments and a heater block having a first surface configured to removably receive the one or more configurable insulator segments, in which each of the one or more configurable insulator segments covers only a portion of the first surface. A method for sealing at least one portion of a package using such a heating block assembly is also disclosed.

Provided are a welding device and a welding method that can realize efficient welding in terms of time and in terms of energy. The embodiment includes: a first graphite heater 110 and a second graphite heater 120 that come into contact with a first member 210 and a second member 220; and a first die 130 and a second die 140 that interpose the first and second graphite heaters 110, 120 between each of the first and second members 210, 220 and each die. The first and second graphite heaters 110, 120 have graphite sheets 114, 124 that generate heat by electric power, insulating materials 113, 123, outer covers 111, 121, and inner covers 112, 122 and are configured such that structures of the graphite sheets 114, 124 and the insulating materials 113, 123 interposing the graphite sheets are interposed between outer covers 111, 121 and inner covers 112, 122.

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

An example apparatus for fabrication of a co-cured composite assembly includes a layup tool body with a cavity, a thermal expansion insert inserted into the cavity of the layup tool body and a first uncured composite part of the composite assembly is positioned onto the thermal expansion insert, and a solid internal mandrel configured for insertion onto the first uncured composite part. During curing, the first uncured composite part compacts and reduces in thickness while the solid internal mandrel and the thermal expansion insert each increase in size to apply pressure to the first uncured composite part.
