Elastische Walze sowie Verfahren zur Herstellung einer solchen Walze

摘要

Elastic calender roller to polish paper webs, comprises a structured cladding around a core of alternating cross wound fibers/damping fibers as the inner bonding layer at roller core, and outer functional layer embedded in a soft matrix. Elastic roller with hard metal core and cladding of overlaid wound fiber bundles, comprises cross wound structure, formed by at least two layers wound alternately in opposite directions symmetrically to the longitudinal axis of roller to the cross section surface. Layer of damping fibers is wound over cross wound fiber layers in unified angular lie and a flatter angle than cross wound fibers. Damping layer is covered by further layer of cross wound fibers. An independent claim is also included for an elastic roller where the wound fibers (1) are wound around the roller core (7) at an angle to its axis and parallel to each other. At least two wound layers form a cross wound layer, at an angle (alpha ) to the longitudinal axis (8) which is symmetrical to the cross section surface. The covering layer is composed of at least two cross wound layers with a damping fiber layer between them, at a unified angle which is flatter than the angle (alpha ) of the cross wound layers.
