In a welded film laminate 1, a second protective layer 14 of a first film substrate 2 and a third protective layer 22 of a second film substrate 3 are welded and fixed to each other by an adhesive layer melted out from at least one of a first adhesive layer 11 to a fourth adhesive layer 27 via a first melted penetration portion 6a of the second protective layer 14 and/or a second melted penetration portion 6b of the third protective layer 22. A welding fixed portion 6c is surrounded in a plan view by a first welded portion 33 in which the first adhesive layer 11 and a second adhesive layer 15 of the first film substrate 2 are welded to each other and/or a second welded portion 35 in which a third adhesive layer 23 and the fourth adhesive layer 27 of the second film substrate 3 are welded to each other.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.

In the present invention, a through-hole (2) and a compression periphery part (3a) at which the core of the resin foam (1c) is compressed are provided in a fastening part of a resin-foam core composite plate (1). A cylindrical part (11a) of a metallic fastening member (11) is inserted into the through-hole (2) from the proximal end side of a wall part (4). The fastening member (11) is crimped to the distal end of the wall part (4) via an eyelet member (12) placed on the outside of the wall part (4) so as to forcibly spread the cylindrical part (11a). The fastening member (11) and a counterpart member (A) are fastened together by tightening a nut (14) onto a bolt (13) inserted into the cylindrical part (11a).

Aspects of the present invention are directed to a heat sealed packaging wherein the heat seal is along a curved surface. Additional aspects of the present invention are directed to a device for heat sealing a package on a surface that is curved along the direction of force.

A process for joining fiber composite materials using self-piercing rivets. The process includes contacting first and second panels. The second panel is a fiber composite material. The process further includes elevating a temperature of only a fastening portion of the second panel. The process also includes placing the first and second panels on a die and joining the first and second panels with one or more rivets while the fastening portion is at an elevated temperature.

A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

Provided is a bonding method capable of bonding with an inexpensive structure while avoiding an increase in the overall size of the device. The bonding method comprises: an arrangement step for locating a cylindrical body between two sheet-shaped members; a cylindrical body bonding step for applying an ultrasonic wave from the outer surface of a first sheet-shaped member through a horn part and applying heat from the outer surface of a second sheet-shaped member through an anvil part, in a state in which the cylindrical body is arranged between the two sheet-shaped members; and a shoulder part bonding step for directly bonding, through a pair of heating parts, the two sheet-shaped members to each other while the two sheet-shaped members are interposed between the pair of heating parts.

Machine for welding workpieces made of plastic materials of the type comprising: two workpiece-carrying fixtures each provided with a template having a recess adapted to accommodate a respective plastic workpiece to be welded; a moving assembly adapted to selectively couple and press the two workpiece-carrying fixtures to/against each other, so as to tighten the plastic workpieces housed in the templates one against the other; a vibrating member which is adapted to vibrate on command a first workpiece-carrying fixture; automatic piece locking means adapted to selectively lock/immobilise the plastic workpiece to be welded inside the template of the first workpiece-carrying fixture; and an electronic control unit adapted to drive/control said automatic piece locking means.

A welding device (10a; 10b) for welding an outlet element (12a; 12b) to a packaging material (14a; 14b) has at least one anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, has a holding element (20a; 20b) which the anvil (16a; 16b) is arranged on, and at least one welding die (22a; 22b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one support unit (24a; 24b) for supporting the anvil (16a; 16b), comprising at least one movably supported support element (26a; 26b), which is configured to exert a holding force onto the anvil (16a; 16b) in a welding operation state of the welding die (22a; 22b).
