ABSTRACT:
In the case of an opening roller ring member for spinning machines, teeth are integral with a ring-formed base body, the teeth being bounded by notches which extend essentially in axial direction, and by grooves which extend essentially in circumferential direction. The grooves are deeper than the notches. The lateral flanks of the teeth extend towards the tooth tip with a slope angle towards the radial line. The slope angle of the lateral flanks is smaller than the slope angle of the continuous lateral walls of the grooves, at least in the area of the teeth tips. There is a bend in the slope angle of the side walls of the grooves where the side walls join the slope angle of the lateral flanks, whereby the bend edge either coincides with the transition of the side walls into the lateral flanks, or is situated in the area of the lateral flanks.
