Abstract

An interface for feeding fresh spinning cops ( 19 ) into the transport system ( 21 ) of a textile machine that produces cross-wound bobbins. The interface comprises a centering device ( 33 ), installed in the area of a receiving conveyor ( 1 ), for placing the spinning cops ( 19 ) onto insertion spindles ( 65 ) of transport pallets ( 17 ) circulating in the transport system ( 21 ) and an impressing device ( 26 ) for fixing the spinning cops ( 19 ) onto the receiving spindles ( 65 ). A drive ( 27 ) is arranged in the area of the receiving conveyor ( 1 ) which drive effects the transporting of the transport pallets ( 17 ) on the receiving conveyor ( 1 ) and the actuation of the centering device ( 33 ).
