Abstract:
1. A rotary part for a web-processing machine, said rotary part comprising: a supporting core having a longitudinal axis and two longitudinal ends and defining a plurality of sections, said supporting core mounted at said two longitudinal ends; at least one bearing; an elastically flexible outer sleeve which surrounds said supporting core in a circumferential direction of said supporting core and extends, in at least some of said plurality of sections of said supporting core, between said two longitudinal ends of said supporting core, said outer sleeve on said supporting core non-displaceably mounted on said at least one bearing, said outer sleeve mounted on at least one displacing point at a distance from said bearing so as to be displaceable perpendicular to said longitudinal axis of said supporting core in order for a curvature of said outer sleeve to be adjustable, said supporting core being configured such that said longitudinal axis of said supporting core remains straight when said outer sleeve is displaced perpendicular to said longitudinal axis of said supporting core, said outer sleeve including a plurality of supporting points facing said supporting core and being spaced apart from said at least one bearing, said plurality of supporting points being configured for coming to rest on said supporting core and thereby for defining a bending line of said outer sleeve relative to said supporting core.
