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 =B5m 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 ****osity
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 ****osity 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, ****osity 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 fini****ng, drilling, poli****ng, 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 DE 10.2004.012.081.1 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 tem****al 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
=B7 Micro-Laser-Lines offers total different indicators against all
other laser perforation processes
=B7 it allows a own significant product property/trademark - patent
claims
=B7 MLLl-1 perforation designs indicate a tipping paper perforation
process and supplier company
=B7 wider position ranges of laser perforation line groups as common
ventilation zone obtains a advance air stream distributions into
cigarette filters
=B7 a full perforation line guiding around the cigarette filter assure
constant ****osity results
=B7 several wave line designs for different brands are possible
=B7 number of holes per cm length are constant e.g. 10 or 20
=B7 ****osity ranges from 100 up to 1000 C.U. are possible
=B7 hole sizes from 60 - 120 =B5m
=B7 hole densities from 100.000 - 500.000 holes per Second - in total
=B7 from 1 up 6 perforation lines combines one group
=B7 perforation hole qualities and ****osities remaining in standard
ranges
=B7 other materials and products are perforate or treatable in similar
processes
Laser perforation machines/systems
=B7 existent laser perforation machines are able to modified with new
optical, mechanical and control elements
=B7 low investment of technical modifications because exchanges of
certain elements
=B7 complete MLL-1 devices are adaptable on existent offline laser
perforation machines or other systems
=B7 possibilities to adapt a MLL-1 beam divert unit at online
perforation systems at cigarette making machines
=B7 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 gl*****.
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.
