Abstract
A generally cylindrical opening roller unit of an open-end spinning device includes a unitary ring body having card clothing formed of at least one helical groove formed in the ring body, at least one helical ridge between courses of the groove, and saw teeth defined by transverse cuts on the ridge. The roller unit also includes an integrated annular collar that is at least codiametric with the teeth in order to protect the teeth. An integral transition area between the card clothing and the annular collars eliminates the problem of a tooth gap.
