<p>In an open-end spinning unit 1 having a pivotably mounted cover element 8 for covering a rotor housing 2 of the spinning unit 1, a sliver opening device is incorporated into the cover element 8. The sliver opening device has an opening cylinder housing 17 fixed to the cover element 8 with an opening cylinder 21 supported by the housing 17 for rotational sliver opening operation. The housing 17 defines a sliver infeed position and a downstream soil discharge opening 28. The opening cylinder housing further includes side walls 43, 44 perpendicular to the axis of the opening cylinder 21, the side walls presenting inner wall surfaces 45 which diverge at least in the area of the soil discharge opening 28 toward respective wall edges 49.</p> |
