The invention relates to a double-disk seal for top rollers of drafting assemblies. According to the invention, a roll body (2) is rotatably mounted on each end of an axle (6). Said double-disk seal comprises sealing disks (25) which are designed and arranged in such a manner that, in order to seal, they form a narrow slip-free sealing gap against the roller body (2). These sealing disks (25) are axially supported by supporting elements, of which at least one is provided in the form of an angle ring (24). The supporting elements (24) are realized in such a manner that another sealing gap (19, 20) is situated in front of each outer sealing gap located between the sealing disk (25) and roller body (2). The complexity of production and assembly as well as the occurrence of failures are reduced due to the inventive double-disk seal. |
