CYLINDER FOR THE GUIDING OF ENDLESS WEBS OF MATERIAL |
摘要 |
A hollow cylinder exhibits an internal body, which forms a sickle-shaped space by means of a partial cylindrical surface arranged eccentrically to the hollow cylinder, with a smaller radius than its internal radius. In this space there is created a vacuum on rotation of the hollow cylinder. By this means air is sucked out of the area through the boreholes of the hollow cylinder, where a web of material wraps the hollow cylinder. This leads to a firmer adherence of the web on material to the hollow cylinder.
