<p>Back rotation of partially twisted flexible rubber or synthetic plastic rings, especially sealing rings for waste water pipes, in a stable equidirectional base position, so that the rings (1,7,9,10) are maintained in centrifigal rotation by a rotation drive (2,4) excentric to the ring axis until the rings attain their stable uniform base position. An independent claim is included for a device for back rotation of partially twisted flexible rubber or synthetic plastic rings.</p> |
