ABSTRACT:
The invention relates to a tubular bobbin core onto which roving or slubbing is wound and which is able to be transported overhead with its axis substantially vertical, suspended by its upper part. In order to avoid unwinding of said roving or slubbing during core transport, said core shows, in a tube portion below the wound area, at least one projecting part which can grip the running end of the roving or slubbing wound on by a winding machine or freely uncoiling from the wound bobbin.
