Abstract
An apparatus for transporting roving bobbins (Y) along a transportation rail (5) arranged between a spinning process (3) and a roving process (1), comprising bobbin carriages (11), each having a plurality of bobbin hangers (13) for suspendingly holding roving bobbins (Y) and movably supported by the transportation rail (5); a driving device (18) for intermittently displacing the bobbin carriage (11); and a roving stripper (35) arranged midway of the transportation rail (5) for clearing off a residual roving on the roving bobbin (Y) during the transportation of the carriage (11). A miss bobbin treatment device (40) is provided midway of the transportation rail (5) between the roving stripper (35) and the roving process (1), for automatically removing a miss bobbin from which the residual roving is not completely cleared off by the roving stripper (35) from the bobbin hanger (13) and, instead, donning a normal empty bobbin (Y) onto the bobbin hanger (13), whereby the efficiency of the apparatus is greatly enhanced.
