Laser perforation in general
Possible to perforate by pulsed or enlarged and focused laser beams are holes sizes from 60 to 200 microns at density of holes of typical 10 to 30 holes per cm, holes sequences from 100.000 to 400.000 holes per second at a maximal of 16 punctured rows by laser distributed over the material web width with traditional systems or machines.
Means in cigarette, tipping, plug-wrap, filter, packaging, packs, tear tape, plastic, film, foil and other material webs. With porosity levels from 100 to 3000 C. U., normally in 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 patent grant and applied laser cluster perforation technology
IPM developments of laser cluster perforation technology LPM-1 is patent grant by DE102004001327 and operates with quadruple beam inputs up to 8 KW to a high power twin level 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 2,500.000 holes per second, jumbo roll-by-roll production, optical online permeability and perforation line position control, porosity feedback, high automation level and other features. Each laser perforation lines are archive able from 100 up to 1000 C.U.
The conception of high power twin level laser beam multiplexer enables plenty capabilities in other industry applications field as cutting, cut-off, welding, surface finishing, drilling, ablation, micromachining, polishing, forming, melting, surface treatment, roughness improvement, etc. Each of 200 single perforation heads can positioned across the through running web or static positioned material.
The fully automatic processes, equipments and devices open outstanding possibilities in industry, domestic, tobacco product, paper converting, manufacturing, refiner, gift material, printing, labeling, laminating, plastic, film, foil, tear tape, gluing tapes, packaging, medical, hygienic, biological, wall covering, security cards, bank notes, house building, construction, food, fruit, agriculture, bioengineering applications and markets.
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 electrostatic perforation.
The world-wide new and patent pending DE102004012081 Micro-Laser-Line technology generating cluster pattern, micro holes, sinus, waves, zigzag, cryptograms, logos, holograms, brand names or other kind of perforation designs in web direction which can looks like as a group of micro laser lines.
Concerned tipping paper means: non coaxial circumference at the cigarette filter.
New beam divert moving, scanning, flipping elements control each single laser perforation lines in across material direction which are precise focused for micro holes in ranges from 50 up to 120 micron.
Technical solutions
Technologically this is performed by means of Piezo oscillators, ultra fast mini scanner, laser beam deflection, actuator with metal optics or asymmetrically, rotary reflection cones, which function and operational sequences is precise synchronize with the speed of web material.
Envelope curves of the selected perforation pattern are storage and calculated by PLC control before single holes and holes groups supervised during production processes.
Product and process advantages
Micro-Laser-Lines enables total different product indicators against all other laser perforation processes
it allows significant product property and trademark indications, patent claims
MLL-1 perforation design indicates unique the company which had generate the micro perforation in tipping, packaging or other material webs
wide range of laser perforation groups as common active ventilation zone to obtain several advances in air stream distributions into cigarette filter
fully perforation line guiding around the cigarette filter assure constant porosity results
several pattern or wave line designs for different brands are possible
number of holes per cm length are constant e.g. 10 or 20
porosity range from 100 up to 1000 C.U.
hole sizes from 50-120 micron
hole densities from 100.000-500.000 holes per Second in total
from 1 up 6 perforation pattern or lines can combines one group
perforation hole quality and porosity remains in standard levels
many other web material, substrate or products are treatable in similar processes
Laser perforation machines and 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
capability to adapt MLL-1 beam divert devices/unit at online perforation system at cigarette making machine
perforation power and production output remains as before
Applications
The MLL-1 Micro-Laser-Line perforation for web or sheet material as paper, metal, isolation, plastic, film, foil, leather, textile material enables now large number of possibilities for hole positioning with different perforation pattern, design, wave, zigzag, cryptograms, scripts, etc. lines or others which generates e.g. optimized air distribution characteristics in cigarette filter, unique anti counterfeiting indications and 100 other product advantages.
Special remark of MLL-1 creates fundamentally new product properties, e.g. as final products for mouthpieces with tipping paper at cigarette filter or other tobacco, packaging or security products.
Specific indication of brand names which is recognizable for everyone and product buyer, if the micro holes or pattern are to see with magnified glasses.
Or touch able as Braille scripts as micro cluster perforation cryptograms.
Summary
The MLL-1 targets many new applications with laser beam diverts in horizontal or vertical position.
Uses of sophisticated divert elements allows easy and low budget modifications at existent laser systems and production machines.
