  • Opening roller housing for an open-end spinning device, device for an opening roller housing and procedure for modernizing spinning devices
    Patent number: 6880322
    Abstract: An exchangeable insert is proposed as auxiliary equipment for a housing of a disintegrating apparatus of an open-end spinning apparatus. The insert is adaptable, so that the disintegrator roll housing can be made to conform to various spinning conditions. In a partial zone, in accord with this proposition, the insert replaces a circumferential wall of the disintegrator roll housing, wherein the insert extends itself into to a zone of a contamination separation opening of the disintegrator roll housing. Its extension in the axial direction is so chosen, that it, at least partially, forms a portion of the circumferential wall of the disintegrator in the area of the contamination separation opening.
