transverse carrier arms 4a and longitudinal carrier rails 4b the transverse carrier arms 4a and longitudinal carrier rails 4b are suspended from the roof 5 or a ceiling of a workshop by suspension links 4c as also evident in connection with fig2 frame structure 4 is used for mounting a plurality of transverse rail elements 6 extending horizontally on both sides of the longitudinal symmetry plane of the ring spinning machines and arranged in an array transverse rails 6 thus extend parallel to one another and perpendicular to the longitudinal planes 29 of ring spinning machines 2 defined on transverse rails 6 are bobbin stations sp for bobbins to be spin stripped the number of such stations at least corresponding to the number of spinning stations of ring spinning machine 2 in the embodiment shown there are additionally provided bobbin stations greater than the number of bobbins being spin stripped for use by stand by bobbins suspended from frame structure 4 by means of suspension links 10 are guides 8 for guiding the slubbings 9 to be spin stripped from bobbins 7 guides 8 may be in the form of sheaves in which case a separate guide is provided for each slubbing 9 it is.
