Anti counterfeiting, indicators or special product designs with laser perforation technology

Laser perforation in general
Possible to perforate by pulsed or enlarged and focused laser beams are holes sizes from 60 to 200 µm at density of holes of typical 10 to 30 holes per cm, holes sequences from 100.000 to 500.000 holes per second at a maximal of 16 punctured rows by laser distributed over the width of the web with traditional systems or machine. Their porosity levels range from 100 to 3000 C. U., normally with web widths from 100 to 500 mm at web speeds of up to 600 m/min, depending on porosity and material consistency in relation to its ability to perforate.

IPM’s Laser perforation technology
IPM owns development of LASER PERFORATION technology LPM-1 is patent grant by DE 102004001327 and operates with quadruple beam inputs up to 8 KW to a high power CO2 laser beam multiplexer to generate up to 200 individual laser perforation rows across the web, combines automatic positioned laser perforation heads, focus setting, web speeds up to 400 m/min, web widths up to 2000 mm, up to 2,000.000 holes per second, jumbo-roll-by-roll production, optical online permeability/perforation line positioning control, porosity feedback, high automation grad and other features. Each laser perforation lines are archive able from 100 up to 1000 C.U.

The conception of high-power laser beam multiplexers enable many possibilities in other industry application fields as cutting, cut-offs, welding, surface finishing, drilling, polishing, forming, surface treatment, roughness improvement, etc. Each of the 200 single perforation head can be positioned across the running web or static positioned material. The automatic processes, equipments and devises opening completely new possibilities in industry, science, military or space laser application.

Working principle of MLL-1 Micro-Laser-Line perforation
As known OFFLINE laser perforation machines or processes generating strait holes lines in web direction of the running tipping or other material sheets. Excluding spray laser designs which looks similar as random holes into certain zone areas as electro static perforation.
The world-wide new and patent pending DE102004012081 Micro-Laser-Line technology generating SINUS, WAVES, ZIG-ZAG, CRYPTOGRAMS, LOGO, HOLOGRAMS, BRAND SIGNS or other kind of perforation hole lines in web direction which looks as a package design of micro laser lines.

Concerned tipping paper it means NON COAXIAL around the cigarette filter.

New beam divert moving, scanning, flipping elements steering each single laser perforation line in across direction which are precise focused for small holes to the fast running paper or other material webs.

Technical solutions
Technologically this is performed by means of Piezo oscillators, ultra fast mini scanner etc. for laser beam deflections, as actuators with added metal optics or asymmetrically, rotary reflection cones, whose function and temporal operational sequences are coupled with the path speed of web material.

The points of envelope curves of the selected perforation form are calculated and computed before for the single holes and holes groups implemented and supervised during current perforation procedure by programmable control system PLC.

Product and process advantages
• Micro-Laser-Lines offers total different indicators against all other laser perforation processes
• it allows a own significant product property/trademark – patent claims
• MLLl-1 perforation designs indicate a tipping paper perforation process and supplier company
• wider position ranges of laser perforation line groups as common ventilation zone obtains a advance air stream distributions into cigarette filters
• a full perforation line guiding around the cigarette filter assure constant porosity results
• several wave line designs for different brands are possible
• number of holes per cm length are constant e.g. 10 or 20
• porosity ranges from 100 up to 1000 C.U. are possible
• hole sizes from 60 - 120 µm
• hole densities from 100.000 - 500.000 holes per Second – in total
• from 1 up 6 perforation lines combines one group
• perforation hole qualities and porosities remaining in standard ranges
• other materials and products are perforate or treatable in similar processes

Laser perforation machines/systems
• existent laser perforation machines are able to modified with new optical, mechanical and control elements
• low investment of technical modifications because exchanges of certain elements
• complete MLL-1 devices are adaptable on existent offline laser perforation machines or other systems
• possibilities to adapt a MLL-1 beam divert unit at online perforation systems at cigarette making machines
• perforation power and production outputs remains as before

Applications
The Micro-Laser-Line perforation MLL-1 for web or sheet materials as like any kind of paper, metal, isolation, plastic, leather, etc. materials enables now large degrees and freedom of hole positioning by different perforation designs of wave, zigzag, cryptograms, etc. lines or other designs which generating e.g. optimized air distribution characteristics in cigarette filters or other additional product advantages.

The special remarks of the MLL-1 create fundamentally new product properties, e.g. as final products for mouthpieces with tipping paper at cigarette filters or other products of this kind which completely specific a indicated brand name and is recognizable for everyone – if the holes are visible or to see with magnified glasses.
Just as like a perforation cryptogram.

Summary
The MLL-1 micro laser line process allows many NEW applications with certain beam diverts in horizontal or vertical positions. Using of new beam diverts elements allows easy and low budget modifications on existent laser systems.
