Abstract
A damping corrugator roll comprises an outer toothed surface, whose teeth extend over a certain axial length of the roll (2), support means (202) allowing rotation about the axis of the roll, and rotary drive means (1), characterized in that it comprises a cylindrical core which is supported for free rotation at its ends, and whereon a toothed peripheral cylindrical jacket is supported by and interposed or bearing material.
Claims22
A damping corrugator roll comprising a cylindrical core and a relatively thin coaxial tubular cylindrical jacket having an outer toothed surface and rotatably supported in a floatable manner on the cylindrical core by an interposed or bearing material which fills a hollow space provided between the cylindrical core and the cylindrical jacket, wherein:
- a) the cylindrical core is rotatably supported at its ends;
- b) the interposed bearing material is a fluid material with high viscosity values, or a solid material with a highly hysteretic elastic behavior;
- and
- c) friction of the interposed bearing material with respect to the outer skin of the cylindrical core and with respect to the inner skirt of the cylindrical jacket increases as the relative speed between the jacket and the core increases.
