The invention relates to a device for producing a sheet-metal blank by means of laser cutting, including a laser cutting device having a laser cutting head movable back and forth in a transport direction and in a y-direction extending vertically to the transport direction, and a stretching device for stretching a metal sheet accommodated in the laser cutting device. The device includes a first clamping device provided upstream of the laser cutting device for clampingly gripping a first portion of the metal sheet, a second clamping device provided downstream of the laser cutting device for clampingly gripping a second portion of the metal sheet, and a mechanism for changing a distance between the first and the second clamping device such that a tensile stress is exerted onto a metal sheet that is clampingly gripped therewith.

Method and apparatus for releasing a metallic binding element (10) from a sheet metal roll (1), wherein an axial sheet metal edge (8) extends axially across the envelope surface (3) of the sheet metal roll, and wherein the binding element is secured to the sheet metal roll with pre-tension. The location of said axial sheet metal edge (8) or one or more axially protruding sheet metal edges at one of the gables of the sheet metal roll and the location of the binding element are detected to thereby establishing the location of a place where the binding element projects over a sheet metal edge under the formation of a gap (13) between the binding element and the sheet metal roll. A laser beam (23) is focused onto a part (15) of the binding element located above said gap in order to locally heat this part and thereby induce breakage of the binding element.

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.

The present disclosure relates to a processing apparatus for a secondary battery current collector. The processing apparatus includes: a foil uncoiling roller; a composite current collector uncoiling roller; a welding device; a plurality of driving rollers; and a coiling roller. Both the foil uncoiling roller and the composite current collector uncoiling roller are disposed on a feeding side of the welding device. The welding device is configured to weld foil to a portion of a composite current collector. The plurality of driving rollers is respectively disposed on a feeding side and a discharging side of the welding device, and has an equal line speed. The plurality of driving rollers is configured to drive the overlapped foil and the composite current collector to downstream. The coiling roller is configured to wind up the composite current collector having the foil welded thereon.

A conveyor system for rapidly moving and simultaneously processing material sheets through several processing stations, the conveyor system including a chain that moves in an endless loop, and noncontiguous operational and standby skid sections for supporting material sheets and moving with the chain in the endless loop; wherein the conveyor indexes through the processing stations, such that, after each indexing, the conveyor has one skid section that is in operational position associated with each of the processing stations, thus allowing each of the processing stations to operate simultaneously on the associated skid section, during each time period when the conveyor is stopped, after each indexing.

A method and a device for producing a continuous strip-shaped composite material. The device has at least one first casting machine, using which a continuous strand is produced, in particular from steel, at least one rolling stand, which is arranged in line with the first casting machine and downstream thereof. A fully solidified slab of the strand produced using the first casting machine can be hot rolled, and at least one second casting machine, using which a further continuous strand is produced from metal. Between the casting machines, on the one hand, and the rolling stand, on the other hand, a merging unit is arranged, by means of which the slabs can be moved in the direction toward each other in the hot state. The rolling stand is designed as a roll-cladding unit, by which a composite formed from the merged slabs can be hot rolled.

A separator cutting device cuts a sheet-shaped separator with which at least one electrode is laminated. The separator cutting device includes a laser generator configured to emit a laser beam, a scanner configured to control an optical path of the laser beam emitted from the laser generator, and an end mirror configured to reflect the laser beam passing through the scanner toward the separator and disposed at a side of the scanner.

A butt joint deep penetration laser welding method is used for joining facing end sections of flat steel products, each having a carbon content CS<0.02%. In order to improve such a method such that an improved weld quality in terms of geometry and strength is achievable with it, at least one carbon-containing carrier material is inserted into a butt joint gap between the end sections, the carbon content of which is C.sub.T?20.Math.C.sub.S, preferably C.sub.T?100.Math.C.sub.S, and/or carbon is inserted into the butt joint gap or applied to at least one end section, such that the volume of the carbon inserted into the butt joint gap corresponds to 1% to 20% of the volume of a melt produced by a butt joint deep penetration laser welding process.

A coating composition comprising a polyester, a mixture of novolak and resole resins and a vinyl chloride polymer, and the use of these compositions to coat metal containers is disclosed.

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.
