A system and process for fabricating components from sheet material. Various embodiments of the disclosure combine punching of components from sheet material with a scoring process that outlines the components prior to the punching operation. In addition, a system and process where the scored portion of the sheet material that includes the scored outline is subjected to a high compression flattening process prior to the punching operation is disclosed. Performing the flattening operation prior to the punching operation has the effect of streamlining the process. That is, the sheet material can be easily handled and conveyed from the scoring process, through the flattening process, and to the punching process without need for separate handling of the component.

Provided is an epoch-making method in which an original sheet is continuously fed, and a rectangular electrode sheet with a tab can be cut out from the original sheet with a normal laser beam during the continuous feeding. The original sheet 1 is continuously moved. An ear portion 1b is separated from an electrode portion 1a with a first laser beam L1 in an ear portion separating region provided in the middle of movement of the original sheet 1, is taken up at a position where the ear portion 1b is separated, in a direction separated from a running direction of the electrode portion 1a, and the laser beam L1 is moved in the ear portion separating step to cut out a tab 5 connected to the electrode portion 1a, from the ear portion 1b. Thereafter, in the next cutting region, while tension T in the running direction of the electrode portion 1a is applied to a cut portion of the electrode portion 1a, the electrode portion 1a is cut at a predetermined interval with a second laser beam L2 to continuously form an electrode sheet 3 with the tab 5. Thereafter, the electrode sheet 3 with the tab 5 and the separated ear portion 1b are collected.

A continuous feed method for friction stir processing includes continuously feeding a tubular material having a first grain microstructure from a bulk source into a processing chamber, and forcing the tubular material between a die and a textured end portion of a mandrel as the tubular material is advanced through the chamber. The continuous feed method further includes rotating the mandrel within the tubular material while forcing the tubular material across the textured end portion to friction stir process the tubular material and transform a structure of the tubular material from the first grain microstructure to a second grain microstructure. The second grain microstructure is a finer equiaxed grain microstructure than the first grain microstructure. The method further includes converting the tubular material having the second grain microstructure into a stiffened sheet form.

A metal strip and a process for manufacturing such a metal strip are disclosed. In order to be able to reproducibly manufacture a durable metal strip, it is proposed for a butt seam to extend essentially between a first cladding layer of a first strip transverse portion and a second strip transverse portion.

A device for moving at least one cutting and welding arrangement able to cut, then weld a tail of a first metal strip to a head of a second metal strip, includes at least one first carriage holding at least one welding head. The first carriage is movable over a guide path following a first course across a transverse strip region. At least one second carriage is movable separately from the first carriage and holds a cutting head. The second carriage is movable on a guide path following a second course. The welding head is used exclusively for a welding mode, the second carriage is used exclusively for a cutting mode and the two carriages have parked positions on either side of the tail and head widths of the strips. A welding method which is associated with the device is also provided.

The present disclosure relates to an electrode plate processing device. The electrode plate processing device includes: an electrode plate cutting mechanism having a cutting position; and an electrode plate rolling mechanism, through which an electrode plate passes. The electrode plate rolling mechanism includes a first roller and a second roller. The first roller has a vacuum adsorption zone for adsorbing a waste edge of the electrode plate. The cutting position is provided in upstream of the vacuum adsorption zone along a conveying direction of the electrode plate processing device.

A vehicle hood includes a unitary metallic hood frame including a plurality of embosses having respective curved surfaces and a plurality of openings. The vehicle hood includes a metallic reinforcement material welded to a subset of the respective curved surfaces of the metallic hood frame. The vehicle hood includes a hood skin attached to the hood frame. The selective placement of metallic reinforcement material may reduce deflection of the vehicle hood while reducing weight compared to metal supports or a thicker metallic hood frame.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which 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 define a perimeter of 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.
