(Coresta), respective from 50 down to 3 Gurley, position control of micro perforation lines with 0.1 mm accuracy, nano micro pores from 50 nm up to 200 micron diameter by up to 300 pores per cm2. With real time data determining of certain parameters, optical transmission, spectral grades, porosity integrals, envelope curves, internal calculated measuring values.

Thus direct with close loops and feedbacks to the power electronics of fabrics treatment units. Micro perforation or other system makes it possible to compensate any changes in web treatment parameters and their partial locations so that each jumbo roll as well single, quad bobbin sets can be produced quantity and quality controlled without intermediate stops in order of ISO 9001/9002 certifications.

Thus sophisticate, precise, liable, repeat accuracy, easy visualized, optical online measurement techniques archives perfect ways to control and convert pneumatic, fluid, gas, jet streams, static permeability, naturally porous grades, filtration levels, breathable or ventilation effects, etc. at fast moving webs. Their conditions can be easily met by using optical transmission technology thanks to described processing in fully online stationary or scanning control units, extremely small pore dimensions, high fabric speeds up to 1000 m/min by high repetition rates. That completely independent from base material properties as consistency, coloring, density, formation, pin holes, smoothness, stretching, shrinking, brightness, opacity, optical spectral, Raman, property, gauging thickness weight, moisture content and other known influences.

Porosity control of nano or micro porous and/or perforated web material, with laser or electrostatic perforation systems, which are produced in speed ranges up to 600 m/min and web widths up to 2000 mm are difficult to control with pneumatic systems because that methods includes disadvantages such as web tangency, web toughing, material flaking, folds build-up, dust and dirt flowing in the system.

These difficulties are ideally solved with stationary/scanning optical porosity control systems as OPSS-1, OPSS-1-A/B, OPRL-1 A/B which are patent pending by DE10251610 and patent grant 200310104764 in China.

Working principle

The online quality control technique is performed to detect and scan zones, generated nano micro pore areas or lines in using multiple colour sensors and a precise tiny line laser which are linked to sensor internal controller units. It controls roll or bobbin formats as stand along or mechanical coupled devices on existent scanning units which measure material weight, thickness, formation, smoothness, roughness, opacity, etc. in web widths up to 6000 mm.

For lasers or electrostatic perforation in bobbins and wide paper webs online measuring procedure and their devices are indicated, with which same transverse movement and simultaneously collections of perforation positions, perforation profile quality and porosities with two different sensor systems and locations. Zone or line position detection by accuracy of 0.1 mm with a laser line unit, scanning speeds up to 300 mm/s, DSP controller firmware, high-speed serial link up to 230.400 bit/s, industry PC performance, C++ process/visualisation software for production quantity, quality, statistics, LAN to quality control centre, etc.

With transverse movements of both measuring systems across the web width, consisting of line laser to detect the quality and position of single nano, sub micro or macro holes in ranges of 10 nm up to 200 um, groups of holes or determined perforation zones and in the same time as the light transmission sensor unit monitors the porosity profiles and determined their integrals continuously.

Thus direct feedbacks to the perforation or machine system enable the trend compensation of arising changes that production rolls without intermediate stops are high quality and quantity controllable.

Applications

Jumbo roll by roll production for offline micro laser or electro static perforation machines for web widths from 100 mm up to 2000 mm, porosity ranges from 80 C.U. up to 5,000 C.U. with feed backs to each perforation channel and automatic production control. The OPSS-1 system enables a production networking for laser or electrostatic perforation machines in quality and quantity aspects in order of ISO certifications.

As well for porous, filter, permeable paper, packaging, sack, fabrics or other webs at making, finishing, refining or other industry machines or processes.
