ABSTRACT:
An apparatus for automatic exchange of at least one full bobbin with at least one empty bobbin in a flyer, i.e. a flyer doffer, comprises a transport device reaching the flyer acting to transport the full bobbins and the empty bobbins, a doffing region and a mounting region which reach the spindles of the flyer for groupwise exchange of the full bobbins with the empty bobbins on the spindles and a lifting region reaching the transport device for groupwise exchange of the full with empty roving bobbins on the transport device. The doffing region and the mounting region on one hand and the lifting region on the other hand are spatially separate from each other. An exchanging region extending to the doffing, mounting and lifting regions is provided. Advantageously the doffing region and the mounting region are combined in a single doffing and mounting region.
