Claims (8)
1. Menetelmä mineraalikuitumaton valmistuksessa, jossa muodostetaan monikerroksinen kuitumatto primäärikuituma-5 tosta, tunnettu siitä, että primäärikuitumaton kuitujakaumaa kuitumaton leveyden yli mitataan jatkuvasti ja että yhtä tai useampaa kuitumaton ominaisuuksiin vaikuttavaa parametriä ohjataan mittaustuloksen perusteella.
2. Patenttivaatimuksen 1 mukainen menetelmä, tunnettu siitä, että primäärikuitumaton kokoamista halutun paksuiseksi sekundäärikuitumatoksi säädetään eteenpäin kytketyllä säätölaitteella (R2) mitatun kuitujakauman perusteella . 15
3. Patenttivaatimuksen 1 tai 2 mukainen menetelmä, tunnettu siitä, että kuitujen valmistusta ja/tai kuitujen kokoamista primäärikuitumaton muodostamiseksi säädetään takaisinkytketyllä säätölaitteella (Rl) mitatun kuituja- 20 kauman perusteella.
4. Jonkin patenttivaatimuksista 1-3 mukainen menetelmä, tunnettu siitä, että kuitujakauman mittaus primäärikuitumaton leveydeltä tapahtuu optisesti. 25
5. Patenttivaatimuksen 4 mukainen menetelmä, tunnettu siitä, että optinen mittaus on valon intensiteetin mittaus useassa kohdassa jaettuna primäärikuitumaton leveydelle . 30
6. Patenttivaatimuksen 5 mukainen menetelmä, tunnettu siitä, että intensiteetin mittaus tehdään maton kuiduista sironneelle valolle.
7. Mittauslaitteisto, jota käytetään jonkin patenttivaa timuksista 1-6 mukaisessa menetelmässä ja joka käsittää valolähteen ja ilmaisimen, jotka on asennettu kuitumaton V , " · Γ-ί t *" * w vastakkaisille puolille, sekä prosessorin mittaustietojen käsittelyä varten, tunnettu siitä, että ensimmäinen valolähde (9) ja ilmaisin (10) on asennettu primäärikuituma-ton vastakkaisille puolille siten, että taso, jonka il-5 maisimen (10) mittasektori määrittelee, ei leikkaa valolähteen (9) emissiopintaa (e).
8. Patenttivaatimuksen 7 mukainen mittauslaitteisto, tunnettu siitä, että toinen, primäärikuitumattoa vastaan 10 suunnattu valolähde (11) on asennettu samalle puolelle primäärikuitumattoa kuin ilmaisin (10).
