Abstract
A highly permeable drum for the wet or dry treatment of textile material, paper or other permeable materials of a certain width consists solely of 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, and the spacers extend perpendicularly thereto. In accordance with further development of this known structure, the connecting-locking elements to be arranged between the sheet metal strips consist of elements extending from a space between two sheet metal strips into the neighboring space. The result is a simple, readily mountable, and more lightweight construction of the drum shell.
