1. Vals med reglerbar nedböjning, som omfattar en roterbart lag-rad inneraxel ooh en yttre rörformig valsmantel, som är fästad vid inneraxeln i dess mitt eller närä mitten och där den av valsens yttre belastning förorsakade valsmantelns nedböjning helt eller delvis kan elimineras med tillhjälp av medelst i valsmantelns ändar placerade belastningsorgan alstrade stödkrafter, kännetecknad av att stödkrafterna ästadkommes av kulor (11, 35), som är anordnade i ätminstone tre radiella borr-ningar (10, 34), liggande i lika vinklar frän varandra i belast-ningsorganet (9, 11, 33, 35) och pä vilka ett inställbart vätske-tryck verkar och vilka är i kontakt med valsens stationära stöd-konstruktion (20) eller med denna anslutna, ej roterande delar (32).
2. Vals enligt patentkrav 1, kännetecknad av att stödringen (20), pä vilken belastningeorganets (9, 11) kulor (11) verkar, är koncentrisk med inneraxeln (2).
3. Vals enligt patentkrav 1, kännetecknad av att stödringen (32), pä vilken belastningsorganets (33, 35) kulor (35) verkar, är koncentrisk med valsmanteln (1).
