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.
