Abstract

A permeable drum for the wet or dry treatment of textile material, paper, or other permeable materials of a certain width has a screen-like cover supported solely on narrow sheet metal strips or narrow webs. The sheet metal strips extend axially parallel, their extension in width being oriented in the radial direction. The webs are oriented in the peripheral direction and form part of the connecting elements between the sheet metal strips, these connecting elements also carrying the screen-type cover. The connecting elements, also serving as spacers, are formed of one piece and connect two neighboring sheet metal strips. Connection of the spacers with the sheet metal strips is achieved by screws, bolts or the like, of which suitably two in superposition extend longitudinally through bores in the connecting elements. While the web of the connecting element is fashioned to be narrow, the base should be broader in order to provide a good seal for the peripheral region of the drum that is not under a suction draft.
