Opening rolls for an open end spinning apparatus

摘要

A multicomponent opening roll for an open end spinning apparatus includes a core piece, upon which a holder for a tooth-set carrier is fastened. The tooth-set carrier (12) must be exchangeable as is determined by operational wear. In order that the axial width of the opening roll (1) is made independent of the axial width of the tooth-set carrier (12), the core piece (11) possess an axial detent (131) for the holder (13).
