The present invention relates to a composite container which has a bottom film layer and a top film layer at least partially adhered on its lower surface to the upper surface of the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab continuous with the resealable flap, wherein the resealable flap is resealably adhered to the bottom film layer and the pull tab is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to form at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A system and method of performing an operation on a continuous sheet of stock material is provided. More specifically, the present invention relates to a system and method used to perform an operation on a continuous sheet of stock material in a high speed manufacturing system. The continuous sheet of stock material can subsequently be received by a second system that performs a different operation on the continuous sheet of stock material. In one embodiment, the second system forms the continuous sheet of stock material into tabs for container end closures. The system can include an infeed accumulation device and an outfeed accumulation device. The infeed and outfeed accumulation devices enable the system to operate at a variable rate and out of phase with a high speed, coil fed manufacturing system to which the system may be removably integrated. The system can determine if the operation has been performed in at a predetermined location of a portion of the continuous sheet of stock material.

A method and an arrangement for finishing a steel strip including the texturing of the steel strip wherein a texture is applied to the surface of a moving steel strip by means of a single laser beam or a plurality of laser beams directed at the surface of a moving steel strip, and wherein the single laser beam or the plurality of laser beams are position controlled to apply a predetermined texture pattern on the surface of the moving steel strip.

Adaptive smart textiles that facilitate reduced energy consumption are described. In one implementation, a dual pane fabric arrangement includes a first pane of fabric and a second pane of fabric separated by an intra-layer gap, and an insert layer disposed in the intra-layer gap, wherein the insert layer causes a thickness of the intra-layer gap to change responsive to changes in ambient temperature.

The present invention includes an electrode assembly support roller, and a laser irradiation device.

The electrode assembly support roller includes two or more cylindrical roller segments, the two or more cylindrical roller segments are coupled to one shaft for fixation in a spaced-apart manner with a adjacent roller segment, and the laser irradiation device is located to be able to irradiate a separated space formed between the cylindrical roller segments with a laser beam.

A dual pass seam welding method for steels having a Ceq of greater than about 0.45. The first pass welds the immediately anneals the weld. On the second pass, the welder is disengaged, and the weld is subjected to a second anneal.

A method of manufacturing a tubular member for an automotive application that includes providing a flat workpiece of a material; forming at least one lance in the flat workpiece; roll-forming the flat workpiece into a tubular configuration; induction welding a seam of the tubular workpiece after the roll-forming; and trimming the tubular workpiece through the lance after welding the seam.

Provided is an apparatus for forming a tab from a moving original sheet with a laser beam. This apparatus is a tab forming apparatus in a tabbed electrode sheet producing apparatus (100) for moving, in one direction, an original sheet (1) including an electrode portion (1a) obtained by applying an active material layer to a long metal foil (4) and an ear portion (1b). This tab forming apparatus includes: a laser emission device (50) configured to apply a laser beam (L1) to the moving ear portion (1b) to cut out a tab (5) connected to the electrode portion (1a); an ear portion separating portion (70) provided at a position above or below a moving plane on which the electrode portion (1a) moves, on a downstream side of an irradiation point (Pm) of the laser beam (L1), so as to cause a take-up angle () to occur at the irradiation point (Pm) between the ear portion (1b) from which the tab (5) has been cut out and die moving plane; and an ear portion collection portion (80) configured to collect the ear portion (1b) in synchronization with the movement of the original sheet (1), while applying tension to the ear portion (1b) from which the tab (5) has been cut out with the laser beam L1.

A capacitor and methods of processing an anode metal foil are presented. The capacitor includes a housing, one or more anodes disposed within the housing, one or more cathodes disposed within the housing, one or more separators disposed between an adjacent anode and cathode, and an electrolyte disposed around the one or more anodes, one or more cathodes, and one or more separators within the housing.
