Abstract
A highly permeable drum for the wet or dry treatment of textile material, paper or other permeable materials of a certain width has an outer shell comprising narrow sheet metal strips and narrow webs, the extension in width of which is oriented in the radial direction. The sheet metal strips extend axially parallel. According to the further development of this basic structure, the sheet metal strips each consist of at least two strips of half thickness arranged proximate to each other. The juxtaposed sheet metal strips are arranged radially offset with respect to one another so that, at an outer periphery, only half of the total thickness of a sheet metal strip is provided, which arrangement substantially increases the air permeability of the drum.
