A composite sandwich panel includes a first composite part and a second composite part. A plurality of stiffeners extend between the first and second composite parts. A fiberglass composite perimeter edge closeout is positioned along one or more edges of the first and second composite parts. The fiberglass composite perimeter edge closeout controls a magnetic flux to bond the first and second composite parts to the plurality of stiffeners.

A method for simple and economical positioning of two work pieces with one another wherein the pieces are welded using induction heating to melt a polymer in a composite wherein air can be blown on the surface to limit the welding to an area close to the mating surface of the work pieces and to prevent melting of the outer surface which would deteriorate the quality of the outer surface.

A device and method for inductively heating package sleeves including: at least one unit for producing an alternating current, at least one inductor having at least one effective section, and a holding unit having a front holding area and a rear holding area for mounting the inductor, wherein the inductor is connected to the unit for producing an alternating current, and wherein the holding areas arranged in such a way that a gap is formed between the front holding area and the rear holding area, the longitudinal direction of which gap corresponds to the conveying direction of the package sleeves. The effective sections of the at least one inductor may be at least in sections arranged asymmetrically to one another in relation to a center plane lying in the gap.

Provided is a soft container in which a tip portion of a body portion can be blocked with one member. The tip portion of a flexible body portion 10 of a soft container 1 is blocked by a tip sheet member 20. The tip sheet member 20 integrally has a circumferential side portion 21, a shoulder portion 22, and a top portion 23. The tip sheet member 20 is constituted by a self-supporting film molded body 28 having a uniform thickness. The tubular circumferential side portion 21 and the body portion 10 are joined to each other. The shoulder portion 22 is reduced in diameter in a tapered shape from the circumferential side portion 21 toward the tip side. The top portion 23 blocks the tip portion of the shoulder portion 22.

A welding promoting element for an opening device is insertable into a lid (25) of said opening device to connect said lid (25) to a closing element (10) closing a pouring opening (14) of said opening device; the welding promoting element comprises a sheet element (31) provided with a layer (32) of electrically conductive material, with a first layer (33) of heat-sealable plastic material and with a second layer (34) of heat-sealable plastic material arranged on opposite sides of said layer (32), said layer (32) having a thickness comprised in the range 5-15 m and each of said first layer (33) and second layer (34) having a thickness comprised in the range 10-50 m.

An inductor for induction welding of a packaging material having at least one layer of metal foil is disclosed. The inductor comprises a welding surface configured to be arranged opposite the packaging material for heating thereof, and at least one spacing element arranged to protrude from the welding surface in a first direction towards the packaging material, when the packaging material is arranged opposite the welding surface, whereupon the least one spacing element separates the packaging material from the welding surface by an off-set distance. A sealing machine for sealing packaging material and a method of welding a packaging material is also disclosed.

An end effector for welding composite components includes an end effector housing and a welding member mounted to the end effector housing. The end effector further includes a leading roller mounted to the end effector housing forward of the welding member and at least one follower roller mounted to the end effector housing aft of the welding member. The end effector further includes at least one first cooling air jet positioned to direct a first stream of cooling air toward the at least one follower roller.

A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

A device for electromagnetic spot welding of moulded parts includes a pressurizing body, first displacing means configured for moving a pressurizing surface of the pressurizing body against the moulded parts or vice versa to join contact surfaces of the moulded parts to be fused by welding under pressure, an inductor provided in the pressurizing body and configured to generate an electromagnetic field in at least the contact surfaces of the moulded parts, and a mechanical fastener configured to be heated by the electromagnetic field generated by the inductor, or by other means. Second displacing means are configured for moving the mechanical fastener towards the moulded parts and drive the heated mechanical fastener into the joined moulded parts to a position further than the contact surfaces of the moulded parts. A method for electromagnetic welding of moulded parts using the device.
