Abstract: A first method of forming an object (400) includes wrapping foil around a preform (305) to provide a multi-layered structure including a plurality of layers of wrapped foil, and diffusion bonding the plurality of layers and the preform (305) together to form the object (400). A second method of forming an object includes wrapping foil around a preform (305) to provide a multi-layered structure comprising a plurality of layers of wrapped foil, removing the preform (305) from the multi-layered structure, and diffusion bonding the plurality of layers together to form the object (400). A third method of forming an object includes stacking a plurality of layers of foil to provide a multi-layered structure, diffusion bonding the plurality of layers together, and shaping the diffusion bonded multi-layered structure to form the object (400).

Abstract: A laser cutting machine includes at least one galvo having a galvo field of view in which the galvo can cut a material moving with a speed past the galvo. A display in the machine provides an image of at least one pattern to be cut from a material, the pattern comprising of a plurality of objects with each object having a position on the material and each object comprising at least one cut. An optimizer in the machine receives the position on the material of each object of the pattern and assigns a start locations for each cut of each object and a trigger distance for each object to maximize the speed at which the material moves past the galvo while ensuring that each object is cut by the galvo at the object's respective position on the material.

Abstract: 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.

Abstract: A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line. A perforation machine in the line is controlled to define a perforation line between the adjacent lottery tickets. The controlling process includes inputting control variables into a controller associated with the perforation machine, the control variables relating to conditions that determine a desired perforation profile of the perforation line. The controller programs the perforation machine with a specific perforation profile for the perforation line that is generated based on the entered control variables, and changes the perforation profile upon inputting of different values for the control variables. The perforation profile is specifically tailored to the control variables between different ticket production runs, or between tickets in the same ticket production run.
