MLL-1 - micro laser line perforation for web material, other
substrates and applications
Patent pending : DE 10.2004.012.081.1
Base description
As known OFF-LINE laser perforation machines and processes generating
strait hole 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 Micro-Laser-Line perforation technology generating
SINUS, WAVES or ZIG-ZAG or other kind of perforation hole lines in web
direction which looks as a package of micro laser lines.
Concerned tipping paper it means around the cigarette filter.
New divert elements moving each single laser beam in across direction
which are strait focused to the running paper or other material webs
or sheets.
Product and process advantages
* the micro-laser-line perforation is total different against ALL
other laser perforation processes
* it allows a own product property/trademark - patent claims
* a MLLl-1 perforation design indicates 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 are constant e.g. 10 or 20
* porosity ranges from 100 up to 2000 C.U. are possible
* from 1 up 6 into 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
Existent and new laser perforation machines/systems
* existent laser perforation machines are able to modified with
new optical, mechanical and control elements of beam diverts
* the investment of technical modifications are in low budgets
because exchanges of certain elements
* the complete MLL-1 device is adaptable on existent off-line
laser perforation machines or other systems
* possibilities to adapt the MLL-1 beam divert unit at online
perforation systems at cigarette making machines
* perforation power and production outputs remains as before
Applications
For the micro laser line perforation MLL-1 of web or sheet materials
as like any kind of paper, metal, isolation, plastic materials allows
now a large degrees of hole positioning freedom by different
perforation designs in the form of wave, zigzag lines or other forms
which generating e.g. in cigarette filter optimized air distribution
characteristics.
The special remarks of the micro laser line perforation create
fundamentally new product properties, e.g. as final products for
mouthpieces with tipping paper on cigarette filters or other products
of this kind which completely specific a brand name and is
recognizable for everyone - if the holes are visible or to see with
magnified glasses. Just as like a perforation cryptogram.
Technologically this is performed by means of Piezo oscillators 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 hole groups
implemented and supervised during current perforation procedure by
programmable control system.
Summary
MLL-1 micro laser line processes allows many 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.
