2149413 9411573 PCTABS00032 A self-loading controlled deflection roll (10) for forming a controlled pressure nip with another roll (4) along a nip line (N) with a hollow rotatable roll shell (14) rotatable on an axis (16) and a roll shaft (12) extending through the shell and radially supporting the shell along the nip line with axially facing surfaces (73, 73', 73'', 73''') on the shaft and rollers rolling on said surfaces supported on the rotating roll shell accommodating bending of the roll shaft relative to the roll shell fixing their relative axial positions. One roller (86, 87) is axially fixed and the other roller (90, 91) is mounted on a rocker arm (92, 93) loaded with the piston and cylinder (94, 95).

Rouleau à déformation contrôlée et à chargement automatique (10) servant à former une pince sous pression contrôlée avec un autre rouleau (4) le long d'une ligne de contact (N). Le rouleau présente un anneau creux (14) pivotant autour d'un axe (16), ainsi qu'un arbre (12) se prolongeant à travers l'anneau et soutenant radialement l'anneau le long de la ligne de contact, présentant des surfaces face à face en direction axiale (73, 73', 73",73"') sur l'arbre. Des rouleaux roulent sur les surfaces en question appuyées sur l'anneau du rouleau rotatif, permettant la flexion de l'arbre du rouleau par rapport à l'anneau, fixant ainsi leurs positions axiales respectives. Un rouleau (86, 87) est fixé axialement, et l'autre rouleau (90, 91) est monté sur un basculeur (92, 93) chargé avec un piston et un cylindre (94, 95).
