A method and apparatus for making bags from a film that follows a film path through a bag machine includes an input section located on the film path, a sealing section located on the film path down stream of the input section, an output section located on the film path downstream of the sealing section, and a controller, connected to control the sealing section. The sealing section includes a sealer that includes a heater block and a manifold. There is an air flow path from the heater block to the manifold. Air is heated in the heater block in response to a control signal provided by the controller to the heater block. The heated air is provided through the air path to the manifold. A temperature sensor is disposed in at least one of the air path and the manifold.

A system and method for thermoplastic composite welding comprising a cooling means and a heat source. The cooling means cools a heat-side laminate so as to create a thermal gradient in the heat-side laminate. The heat source heats the heat-side laminate after the cooling step is initiated but before the thermal gradient dissipates so that a first side of the heat-side laminate closer to the heat source does not deform as faying surfaces of the heat-side laminate and another laminate farther away from the heat source are welded together.

The invention relates to a high-strength and permanently elastic curable adhesive for bonding at least two surfaces, of which at least one surface is a surface of a permanently elastic plastic, wherein the adhesive is an adhesive that cures in at least two different hardening mechanisms, wherein the first hardening mechanism comprises a chemical reaction to form a chemical bond including a sulphur atom, and the second hardening mechanism comprises the formation of crystalline structures from amorphous polymers. The invention also relates to a method for high-strength and permanently elastic bonding of at least two surfaces to one another, of which at least one surface is that of a permanently elastic plastic, by means of such an adhesive, said method comprising the steps of: applying the adhesive to at least a first of the surfaces to be connected, ensuring conditions under which at least the first hardening mechanism of the adhesive can take place, bringing the first surface into contact with the second surface, and ensuring conditions under which the second hardening mechanism of the adhesive can take place.

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.

An electrode package includes an electrode pad to be attached to a subject, the electrode pad having a gel layer, a lead wire having one end electrically coupled to the gel layer, and a packaging cover having an opening portion, the opening portion being sealed such that the electrode pad and a part of the lead wire are housed inside the packaging cover. A sealing width in at least a part of a section where the packaging cover is sealed together with the lead wire is narrower than a sealing width in a section where only the packaging cover is sealed. A sealing apparatus is configured to seal the packaging cover.

The invention relates to a method for assembling a first metal part with a second part made of a composite material comprising at least one matrix and fibers arranged inside the matrix. The method comprises at least: a step of forming the first part, consisting in producing a plurality of teeth projecting from a contact face of the first part, two adjacent teeth being separated from each other by an interstitial space, the teeth having an end protuberance; and a step of pressing the second part against the first part, in such a way that the fibers of the composite material can penetrate inside the interstitial space defined between adjacent teeth and that the fibers are retained by the end protuberances of the teeth.

A co-consolidation tool, including a heating assembly to receive one or more thermoplastic parts and to apply a consolidation temperature to the one or more thermoplastic parts, a pressure bladder to apply a consolidation pressure to the one or more thermoplastic parts, and a support insert shaped and configured to support and at least partially surround at least one of the one or more thermoplastic parts, wherein at least one of heating assembly and the pressure bladder is shaped to receive and support the support insert.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool.
