... problems with quality of yarn ?
![Page 2: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/2.jpg)
Such pictures are well-known only to machine operators
and/or to the peoples responsible or for quality control and claims

Such woven fabric quality should not leave the plant.

If such fabric is sold to a customer, then in most cases a claim
can be expected which leads to high financial losses.

In this case a yarn with a moire effect is concerned.

The greatest problem for the manufacturer
is to identify the spinning unit
which produces the faulty yarn.

what is
QQM system ???
![Page 14: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/14.jpg)
QQM 4 is the abbreviation for the English name
Quick Quality Measuring.
The digit 4 means the third series in its development
The third possibility - the use of the QQM4 device that enables
them to reveal the spinning units productions a lower quality
yarn directly, in time and with minimum costs and to remove the
defects without delay.
![Page 15: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/15.jpg)
QQM system is based on the optical principle by means of an infrared sensor . It means
that it is not dependent on standard atmosphere (const. humidity and temperature) - it is
not necessary to condition the yarn before measuring.
System detect „optical“ defects !
PROPERTIES - optical principle of measuring
![Page 16: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/16.jpg)
QQM 4 is a device designed for the application in the spinning mills but it does not rule
out the possibility of its laboratory use (as matches format and range of results). Its
minimized dimensions, mechanical resistance and an autonomous power supply allow to
measure the yarn quality directly in the course of its manufacturing - no destruction tests
are necessary.
PROPERTIES - operation device
![Page 17: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/17.jpg)
For a quick rough measuring it is sufficient to scan about 10 meters of yarn. A rotor
spinning machine is reliability measured within 60 min including an evaluation. Unlike
laboratory procedures here the operator can carry out an intervention in the production
process immediately after the measuring. At least to stop production of rejects.
PROPERTIES - quickness and instant reaction
![Page 18: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/18.jpg)
The QQM4 device enables to carry out a 100% operation control of all SU‘s and indicate
units producing faulty yarn. By ONE device is possible measuring on more machines
of different types and technologies (unlike the ON-LINE sensors).
It increase utility value of QQM system
PROPERTIES - portability
![Page 19: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/19.jpg)
System QQM-3 scan optical picture of yarn by measuring head, which operating staff put
into yarn delivery way. It allows measuring both on the OE rotor and on the ring spinning
machines. Operation staff have to choose right technology before each measuring only.
Universality consists in independence of colour, rough and type of yarn.
PROPERTIES - universality
![Page 20: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/20.jpg)
PROPERTIES - modularity
QQM system has 4 types of measuring
1. INDICATION- measuring time about 10 sec
- comparing of quality in terms CV% 10 meters of yarn
2. MEASURING- measuring time about 1-3 min
- detailed measuring of yarn
3. ANALYSIS- measuring time about 3-10 min
- detailed measuring of yarn and spectral analysis
4. DATA SOURCE- data gathering for analyse on PC
( only ONE hardware with software modules )

MEASURING
measuring time about 1-3 min(depending on measured length and delivery speed)
Results:
- Y.C. (yarn count - fineness [TEX])
- U%, CV%, CV% in cut lengths

Open the way to
Total Production Maintenance !!!
QQM system does not only discover that spinning quality
tends to degrease - can give you also the idea what could be
the reason for this tendency.
Usually, if this tendency is already discovered, you have
time to decide about the maintenance action without
immediate break of spinning process.
![Page 31: Qqm4 en](https://reader034.vdocuments.mx/reader034/viewer/2022051414/55a3774d1a28ab9e3a8b4585/html5/thumbnails/31.jpg)
What can you win with
QQM system ???
- claim decrease
- stabile quality
- higher mills capability utilization rate
- decrease in needs of replacement parts
- maintenance capacity saving
