[origin: EP0310871A1] In a method for the automatic exchange of roving bobbins (12) on ring spinning machines, first a new roving bobbin (12) is extracted from a transport device (13) and stored intermediately in a maintenance carriage (11), and then the old roving bobbin (15) is extracted from the creel, without interrupting the run-in of the roving, and transferred to the transport device, after which the new roving bobbin (12) is extracted from the maintenance carriage and introduced into the creel. The start of the roving of the new roving bobbin is joined to the roving of the old roving bobbin, after which the roving of the old roving bobbin is severed. <IMAGE>
