Device for cutting a web of material
A device for cutting a web of material comprises movement means for moving a web of material to be cut, defining a feed path for the web at least partly rotatable about a central axis and equipped with at least one conveyor mounted around the central axis, at least one cutting head equipped with a laser source and an optical system configured to direct the laser beam towards a cutting zone, where the optical system of the cutting head comprises at least one directing member located inside the conveyor to direct the laser beam away from the central axis towards the cutting zone.
ENGRAVING IN A COMPUTER NUMERICALLY CONTROLLED MACHINE
A method for dithering can include receiving, at a computer numerically controlled machine comprising a laser, a motion plan corresponding to a first image. The output of the laser can be dithered, in accordance with the motion plan, to effect a change in a material within an interior space of the computer numerically controlled machine. The change can substantially reproduce at least a portion of the first image on the material. The dithering can include providing laser energy to the material at a native resolution based at least on a spot size of the laser. The spot size can be determined based at least on one or more parameters of the computer numerically controlled machine and/or one or more properties of the material. The laser energy can be delivered at locations separated by a distance no less than the spot size.

A METHOD AND AN APPARATUS FOR PRODUCING A RADIO-FREQUENCY IDENTIFICATION TRANSPONDER
Method and apparatus for producing RFID transponders (400) arranged on a carrying substrate, comprising:providing a first substrate (100), the first substrate having at least one antenna element (101) arranged thereon, and preferably several antenna elements arranged sequentially thereon along a longitudinal extension of the first substrate, each antenna element being formed by an electrically conductive pattern; providing a second substrate (200), the second substrate (200) having at least one RFID strap, each RFID strap comprising an IC (202) and at least one contact pad (201) coupled to the IC, and preferably several RFID straps being arranged sequentially along a longitudinal extension of the second substrate; and electrically connecting an antenna element (101) on the first substrate to the at least one contact pad on the second substrate by bringing said first and second substrates together, thereby bringing said antenna element in mechanical contact with said at least one contact pad, and heating the contact pad(s) to a temperature at least equal to a characteristic melting point of said at least contact pads, thereby electrically connecting the antenna element to said at least one contact pad.
Method for producing packaging, and packaging machine
The invention relates to a method for producing packaging (18) from paper material (5), in particular paper, cardboard or paperboard, said method comprising the following steps: forming packaging (18) from a blank (19) made of paper material (5), which paper material overlaps at at least one joining site (21); positioning the at least one joining site (21) between a sonotrode (2) and an anvil (3); applying the joining site (21) with a joining force in a joining force direction (6); and making the sonotrode (2) ultrasonically vibrate in order to ultrasonically weld the paper material (5) at the joining site (21), which method is characterised in that the paper material (5) is moistened, preferably on the inner sides of the joining sites (21), before forming the packaging (18) and/or while forming the packaging (18) and/or after forming the packaging (18) and/or during the ultrasonic welding.
Label imaging and cutting
The present invention discloses a method and apparatus for imaging and cutting a label from a linerless label substrate 6, the substrate 6 comprising: a paper or polymeric film base layer; a colour change layer, incorporating a colour change compound operable to change colour in response to illumination by a laser 1; an adhesive layer; and a release layer adapted to have low adherence to the adhesive layer. The label substrate 6 is transported from a storage reel to an imaging area. At the imaging area, the label substrate 6 is selectively illuminated by laser 1 to form an image in the colour change layer. Subsequently, further laser illumination is used to cut the label substrate 6 thereby providing a single label for application to an object. The invention is characterised in that the laser spot size is varied for imaging and cutting.
Methods and apparatus for laser cleaning of fabric Materials
Disclosed are methods and apparatus for cleaning a substrate, such as a fabric material, involving the application of optical energy to the substrate, typically in the form of a beam of light, where the energy of the beam causes removal of the contaminant from substrate, such as from the fibres of a fabric material. The cleaning may occur via any mechanism, including one or more of, alone or in any combination, ablation, melting, heating or reaction with the substrate or contaminant or agent introduced to aid in the cleaning. The optical energy is typically applied to a selected area of the substrate (e.g., as a beam), and the substrate and beam or optical energy source moved relative to one another so as to clean a larger area of the substrate, either by moving the substrate or the beam, or both. Movement of the beam with respect to the substrate can be attained through a beam scanning mechanism or through movement of the optical source itself.
Support needles for laser cutting of paperboard
A support system for holding a sheet of material being cut by a laser has a base and a number of needles extending upwardly from the base. A vacuum generator or suction mechanism is in communication with a lumen in each needle to hold the sheet atop the bed of needles and spaced from the base so as to avoid scorching the sheet by the laser.
System and method for variable perforation profiles in a stack of lottery tickets
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.
Method for Producing Corrugated Cardboard Blanks, and Device
The invention relates to a method for producing blanks from paper, cardboard, paperboard, corrugated cardboard, or plastic. The method according to the invention does not process panels or sheets into blanks in a multistage process but rather produces the blanks directly from the material web i.e. the corrugated cardboard web or from the paper, paperboard, plastic or cardboard web. The machining process is scalable. Advantageously, the method according to the invention can be adjusted in terms of the required production or packaging quantity by the juxtaposition of additional processing centers in terms of production speed and quantity.
