The embodiment provides a heat-sealing apparatus and a method of accurately controlling heat sealing temperature by measuring the temperature using a heat-sealing apparatus which heat-seals a pair of heat seal materials by nipping them between a pair of heating bodies. The method of heat-sealing includes mounting a cover material on the surface of at least one of the heating bodies to be in contact with the heat seal material, attaching a minute temperature sensor to the surface of the cover material on the side to be in contact with the heat seal material, and controlling temperature of welding face by the temperature detected by the minute temperature sensor, and an apparatus therefor.

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.

Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A welding apparatus (1) for radio-frequency, RF, welding, comprises: a clamp (10) having two electrodes (100, 101; 100′, 101′) being movable with respect to one another for clamping one or more items (2; 2′) therebetween for a welding process; and an RF power supply (11) for providing an RF welding current to the electrodes (100, 101; 100′, 101′) of the clamp (10), the RF power supply being adapted to change the frequency of the RF welding current during the welding process.

A method for producing elastic laminates includes gripping first and second continuous elastic films in respective gripping zones by respective first and second stretching members, transversely stretching the first and second continuous elastic films by rotating said first and second stretching members about respective first and second axes of rotation inclined with respect to each other, and releasing the transversely stretched first and second continuous elastic films from the respective first and second stretching members in respective release zones aligned along a common transverse release line.

Riveted assemblies are provided that can include a substrate extending between two ends to define opposing substrate surfaces having a first opening extending between the opposing substrate surfaces; a metal-comprising substrate extending between two ends to define opposing metal-comprising substrate surfaces having a second opening extending between the opposing metal-comprising substrate surfaces. The riveted assemblies can further provide that the first and second openings complement one another when the substrate and metal-comprising substrate are engaged; and a rivet shaft extends through the openings and engages the substrate with the rivet head and the metal-comprising substrate with the rivet stop head, at least a portion of the stop head being mixed with, and forming a metallurgical bond with the metal-comprising substrate. Assemblies are provided that can include a rivet stop head mixed with, and metallurgically bonded with a metal-comprising substrate. Methods for affixing substrates to one another are also provided. The methods can include providing a substrate defining an opening configured to receive a rivet shaft; providing a metal-comprising substrate defining a complimentary opening; operatively engaging the substrates with the rivet shaft; and forming a stop head from the rivet shaft to affix the substrates. The method further includes that the stop head mixes with, and forms a metallurgical bond with the metal-comprising substrate. Methods for mixing materials to form a metallurgical bond are also provided. The methods can include forming a metallurgical bond between a stop head of a rivet and a metal-comprising substrate.
