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.

The following simplified summary is provided in order to provide a basic understanding of some aspects of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later. In certain embodiments a system for opening packages is provided comprising a conveyer for supporting or conveying a package, wherein the package comprises a surface material and a measurement zone wherein the package is inspected and measured for a cutting operation to thereby determine a process location comprising a location on the package for introduction of a cut to the surface material.

A laser marking system for marking a length of material includes a laser device for emitting a marking beam. A motor moves the length of material relative to the laser device. A sensing system detects a predetermined movement of the length of the material and provides a speed signal and a distance signal, and a controller is provided in operative communication with the sensing system and the laser device for receiving the speed signal and the distance signal and responsively directing the marking beam of the laser system onto the length of material in a predetermined pattern.

A transporting system, for laser processing a workpiece. The system uses a metal belt, formed of a metal material. The belt is formed into a continuously moving conveyor that has plural holes therein that are between 0.005 in diameter and 0.025 inches in diameter, and are spaced 10 mm but 5 mm from one another. The holes are beveled in cross-section at an angle between 40 degrees and 60 degrees to form a smaller hole size at the outer surface and a larger hole size at the inner surface. A vacuum source is connected to apply vacuum to the inner surface of the belt, to each of the larger size sections of the plural holes. A vacuum source is connected to apply vacuum to the inner surface of the belt, to each of the plural holes. A laser system, directs its output beam towards a laser processing area in an area of the belt on the outer surface to process the workpiece.

A method and device for the plasma perforation of tipping paper, wherein a low temperature plasma is generated on the surface of the tipping paper by briefly ionizing a gas mixture using an energy source that is as close in form to a point as possible, wherein the ionizable gas mixture is locally restricted to a very small surface region of the tipping paper.

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.

A method for producing a diffusion-optimized tipping paper for tobacco products, especially filter cigarettes, by plasma perforation of the web of tipping paper for the purpose of maximum carbon monoxide reduction, wherein the diffusivity and the permeability P of the perforated tipping paper are measured in-line and diffusivity is maximized by controlling the perforation parameters, the definable target permeability P.sub.soll being maintained at all times.

In an apparatus (1) and a method for creasing and cutting sheets of material for packaging or display, or corrugated carton structure material such as cardboard or corrugated cardboard, a sheet S.sub.x to be processed is fed sequentially through an optical station (100), a creasing module (200) and a laser cutting module (300) for being sequentially creased and cut, and wherein the creasing and cutting status work profiles are input by a programming logic controller (PLC) by way of a Job Processor, and wherein the speeds of the conveyor belts that convey the sheets, are adjusted automatically by a processing unit based on parameters of the creasing and cutting operations.

A re-closable container 1 comprises a container body 5 having an opening at an upper end for receiving and retrieving at least part of a content of the container body 5 and a zipper 3 for selectively closing and releasing the opening. The zipper 3 has a zipper line 11 along which the zipper extends from a first side 13 to a second side 15 of the container body 5. A notch 17 is arranged underneath the zipper line 11 and at the first 13 or/and at the second side 15 of the container body 5, wherein the notch 17 is configured to remove the zipper 3 by tearing off the zipper 3 from the container body 5 along a tearing line 19.
