The bobbin change appts., particularly for condenser bobbins in a carded yarn double-sided ring spinner, has a feed pivoting on a generally horizontal axis on a frame of the spinner, with a holder for the condenser bobbin to be filled. A removal and advance mechanism moves in a generally vertical direction within the frame to engage the bobbin holder. The feed pref. has two symmetric swing clips at a gap from each other, each with a holder for the bobbin at the opposite ends to the swing axis, displaced by about the width of the condenser bobbin. Each holder is a shaped section, with a recess at an angle to the longitudinal axis of the clip, above a hook, so that the recess runs conically towards the hook. ADVANTAGE - The appts. gives an automated bobbin exchange action.
