Abstract
A screen drum design is known whose drum jacket consists of axially extending sheet metal strips whose widths extend in the radial direction. These sheet metal strips must be permanently attached to the end bottoms to produce the drum jacket. According to the invention, this connection is made movable. For this purpose, a connecting element (17) is provided that consists of one or two connecting arms (18, 19) connected with one another so that they are pivotable with respect to one another, said arms being connected, with articulation at their free ends, with either sheet metal strips (13) or a centering ring (29) for the sheet metal strips, or with bottoms (11, 12) that are located at a distance from the ends of sheet metal strips (13) and/or centering ring (29). In this way, movement of the drum jacket relative to bottoms (11, 12) is always possible to compensate for dimensional changes resulting from temperature fluctuations.
