ABSTRACT:
A screen drum design is known whose drum jacket consists of sheet metal strips running axially and whose width extends in the radial direction. These sheet metal strips must be permanently connected with the endwise bottoms to produce the drum jacket. According to the invention, this connection is made movable. For this purpose, an articulated ring (32) is used that consists of a number of connecting arms (13) mounted pivotably, said arms being connected with articulation at their free ends either with sheet metal strip structure (13, 14) or with bottoms (11, 12) that are located at a distance from the ends of sheet metal strips (13). In this way, movement is always possible between the drum jacket and bottoms (11, 12) to compensate for dimensional changes as a result of temperature fluctuations.
