摘要： 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 rind 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.

摘要： A spinning device comprising a spinning box housing; a spinning rotor having a spinning cup on a rotor shaft; a cover element; a traveling belt acting tangentially on the rotor shaft; a rotor brake; a pivotable expander roller moveable within a maximum pivot angle via a pressure lever system connected to the brake gear of the rotor brake between an operative position when the spinning box is closed in an inoperative position wherein the expander roller is automatically lifted off the tangential belt and the rotor brake is applied to the rotor shaft when the spinning box is opened; a brake and locking lever having a locking recess in contact with an arresting roller arranged on the cover element; and an arrangement in the pressure lever system for absorbing shock-like forces acting on the expander roller and for preventing the forces from being transmitted to the brake and locking lever.
