摘要:
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 Psoll being maintained at all times.
摘要:
Cutting systems and methods capable of performing a variable cutting operation on a continuous web. The system includes a first cutting apparatus configured to receive the web and perform a cutting operation thereon to produce unfinished documents, and a second cutting apparatus configured to subsequently perform a trim cutting operation thereon to produce finished documents of selectively defined finished lengths, wherein the second cutting apparatus has a feed direction that is perpendicular to a feed direction of the first cutting apparatus. The system includes a conveyor system configured to receive the unfinished documents from the first cutting apparatus, arrange the unfinished documents into a stream of shingled documents traveling in the feed direction of the first cutting apparatus, and turn the unfinished documents at a right angle to travel in the feed direction of the second cutting apparatus without changing their orientation.
摘要:
A parallel belt system for a laser cutter module and a method or non-transitory computer readable medium for transporting a cut sheet of media through a laser cutter in a printer is disclosed. For example, the parallel belt system includes a rotating shaft, a plurality of pairs of o-rings movably coupled to the rotating shaft, a plurality of belts for receiving a cut sheet of media, a guide for each one of the plurality of belts for holding a respective one of the plurality of belts rigid, a laser cutter for cutting a portion of the cut sheet of media and a collection module coupled below the plurality of belts for collecting the portion of the cut sheet of media that is cut by the laser cutter.
摘要:
Method and design of a pressure vessel having an internal supportive structure that reduces pressure forces applied to the external shell of the vessel by distributing such forces via internal bonds mostly connected to a central supporting element. The method and design allow making much lighter and stronger pressure vessels and containers using additive manufacturing technology, known as 3D printing.

摘要:
Providing a method of manufacturing a laser processed part by using a protective sheet for laser processing capable of effectively suppressing contamination of surface of workpiece by decomposition product, and processing at high precision, when processing the workpiece by optical absorption ablation of laser beam. It is also an object to present a protective sheet for laser processing for use in the manufacturing method of laser processed part.
摘要:
The present invention includes methods for treating laser-processed materials having an odor generated during the laser processing. The present method includes treating the laser-processed materials with heat to dissipate the odor from the material. The laser processed material may be secured to avoid curling during the heating process. The method can also include a cooling step after heating of the laser-processed material. Multiple cycles of heating and cooling may also be performed to substantially reduce or eliminate the odor from the laser-processed material. The invention also includes articles made according to the method and apparatus for producing laser processed materials having substantially reduced odor.
摘要:
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.
摘要:
A system includes a cutting station having a laser cutter for cutting surface marks, score lines, holes, slots, flaps, panels, etc. into a selected substrate, an image capture device for capturing digital image data associated with the selected substrate, and a computing system for controlling the cutting process. The computing system 32 initiates a calibration test cycle that 1) cuts a test pattern into the selected substrate; and 2) analyzes the test pattern that was cut into the selected substrate. Based on the results of the analysis of the captured image, the system adjusts the operational parameters of the laser cutter during a subsequent packaging production run utilizing the same substrate type.
