ABSTRACT:
A yarn manipulating device for textile packages, e.g., a preparation device (17) for loosening and placing the yarn end (30) of a spinning cop (16) in preparation for use as the feeding bobbin in a winding machine, comprises pneumatic yarn-end receiving member (18) connected via a suction line (23) to a housing (31) which contains an air aperture (33) and a yarn separating device (32) and therefrom to the vacuum system of a textile machine, preferably to a waste collector (24). The suction line (23) connecting the yarn-end receiving member (18) to the housing comprises an end (34) which extends inwardly past the front housing wall (35), as viewed in the direction of flow R of the suction air (36). When suction air (36) is flowing through the housing (31) to aspirate a yarn end, an area of air turbulence (40) forms in the lateral area surrounding the tubular connecting portion (34) which reliably prevents yarn fluff from settling inside the housing (31) and on the operating elements therein and thereby to avoid adversely influencing their operability.
