A film-treatment device has two spaced and generally parallel mounting plates each having a pair of plate holes and respective pairs of journals in the plate holes having respective journal holes centered on a pair of journal axes. The journal holes of the plates are coaxial with each other and the two journal axes are parallel. Rollers centered on respective roller axes each have a pair of substantially cylindrical end trunnions centered on the respective roller axis and rotatably received in a respective one of the journal holes for rotation of the respective roller therein with its roller axis coaxial with the respective journal axis. The journals of one of the journal axes are constructed so the respective roller can move against spring force limitedly away from the other roller. At least one journal of each journal axis is formed at the respective journal hole with two semicylindrical journal surfaces spaced axially apart, centered on the respective journal axis, of the same radius of curvature as the respective trunnion, and diametrally oppositely concave toward each other. Thus the respective trunnion rides on the respective journal surfaces with the respective roller axis lying on the respective rotation axis. This one journal of each journal axis is formed at the respective journal hole with two generally semicylindrical skew surfaces spaced axially apart, centered on respective skew axes inclined to and intersecting the respective rotation axes, of at least the radius of curvature of the respective trunnion, and diametrally oppositely concave toward each other.
