Abstract
A method for backing the inside teeth () of a sliding sleeve () produced by way of powder metallurgy for a manual transmission is described where the backings () of the teeth () forming the front-side pitches () are formed with the aid of a rolling tool () by back rolling accompanied by plastic deformation of material from the backing region. In order to prevent burr formation, it is proposed that the front-side tooth sections () delimited by the backings () are simultaneously calibrated whilst forming and/or calibrating the relevant pitches () with the aid of the rolling tool () for forming the backings ().
