APPARATUS AND METHOD FOR TRANSPORTING BOBBINS AND TUBES BETWEEN ROVING FRAME AND SPINNING FRAME OF A SPINNING LINE

摘要

An apparatus of a spinning line comprises a rail (22) of a roving frame (6), a secondary transport device (26) associable to at least one spinning frame (8), and an integrated device (50) to locally carry out the collection of several tubes (12,14) originating from the spinning frame, of several bobbins (10) originating from the roving frame (6), the exchange of the bobbins (10) with the tubes (12,14) and the release of the bobbins (10) to the spinning frame and of the tubes (12,14) to the roving frame (6). Rail moving means are further provided for, adapted to advance the rail (22) with a variable stroke (C1,C2) between the step of collecting the bobbins (10) from the rail and the step of releasing the tubes (12,14) to the rail.
