Abstract
Roller for machines in the paper-making industry or similar, with a honeycomb-shaped roller element formed by upright straight and corrugated bands, extending approximately in the circumferential direction and alternating with each other in the axial direction, said bands being connected by welded joints. To make passages, which allow a throughflow in the circumferential direction, between the roller element and a fabric cover supported by the latter, openings adjoining the fabric cover are provided in the roller element between the fabric cover and the radially outer edges of the corrugated bands in the area of the connecting points and in the center between the connecting points, and in order to increase the open-passage area of the fabric cover, the latter rests directly on the roller element.
Claims5
A roller for machines in the paper-making industry, said roller comprising a support tube, a plurality of bands attached to the support tube and extending at least approximately in the circumferential direction and standing upright in the radial direction, said bands including straight and corrugated band sections alternating with each other in the axial direction and connected one to another at connecting points, said corrugated band sections having recesses at their radially outer edges approximately in the center between the connectiong points, and a cover fabric forming the circumference of the roller and supported and resting directly on at least the radially outer edges of the corrugated band sections with passages provided between the cover fabric and the bands at the connecting points of the latter in the region of the radially outer edges of the corrugated band sections, said passages allowing a through flow in the circumferential direction.
