    • 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.
    • 一种胶片处理装置具有两个间隔且大致平行的安装板,每个安装板具有一对板孔,并且板孔中的各对轴颈具有以一对轴颈轴为中心的相应的轴颈孔。 板的轴颈孔彼此同轴,两个轴颈平行。 以相应的滚子轴为中心的辊子各自具有一对以相应的滚子轴线为中心的基本上圆柱形的端部耳轴,并可旋转地容纳在相应的一个轴颈孔中,用于使各滚子在其中与其轴线与相应轴颈轴线同轴的旋转。 其中一个轴颈的轴颈被构造成使得相应的滚子能够相对于另一个滚子的限制的弹簧力而移动。 每个轴颈的至少一个轴颈在相应的轴颈孔处形成,其中两个半圆柱形轴颈表面以与相应的轴颈轴线相对的轴向间隔开,与相应的耳轴相同的曲率半径并且彼此径向相对地凹。 因此,相应的耳轴骑在相应的轴颈表面上,相应的滚子轴线位于相应的旋转轴线上。 每个轴颈的一个轴颈形成在相应的轴颈孔处,两个通常为半圆柱形的歪斜表面,轴向间隔开,中心位于相应的旋转轴线倾斜并与其相交的相应的歪斜轴线,至少相应耳轴的曲率半径, 并且彼此径向相对地凹。
