Claims (5)
1. Förfarande för behandling av ett cellulosahaltigt material genom att inmata kontinuerligt materialet tillsam- 5 mans med en reagenslösning i ett arbetsutrymme och pressa materialet upprepade g&nger mekaniskt medelst samverkan av inre och yttre arbetsorgan, vilka är rörliga i förhällande tili varandra och vilka bildar arbetsutrymmet, varvid de yttre organen omsluter de inre organen, känneteck-1 q n a t därav, att steget för upprepad mekanisk pressning av materialet genomförs genom att bringa den ena av organen i en precessionsrörelse och rullning längs det andra organets yta genom materialskiktet, varvid precessionsrörelsen och rullningen förorsakas av massans rotation kring en axel, 15 vilken massa är obalanserad i förhällande tili rotationsaxeln och förenad med nämnda arbetsorgan fritt roterbart kring axeln.
2. Apparatur för genomförande av förfarandet enligt patentkravet 1 och omfattande en stomme och en rotor innanför 2q stommen, vilka tillsaramans bildar arbetsutrymmet, medel för matning av det material som skall behandlas, och reagenslösning tili arbetsutrymmet, en drivaxel och dess drivmekanism, kännetecknad därav, att rotorn (4) utgörs av en roterande kropp, en del av vars yta är framställd tili att 25 pressa mekaniskt och upprepade gänger det material som skall behandlas, att p& drivaxeln (7) är monterade obalanserade vikter (8) och att axeln (7) är förenad med rotorn (4) eller stommen (1) fritt roterbart.
3. Apparatur enligt patentkravet 2, känneteck-5Q n a d därav, att drivaxeln (7) med de obalanserade vikterna (8) är monterad via lagrer (15) innanför rotorn (4), vilken är förenad med stommen (1) via en kulled (14) och att rotorns (4) yttre sidoyta har tili uppgift att pressa mekaniskt upprepade ganger det material som skall behandlas. 35
