The present invention relates to a process and device for knotting a filament on a bobbin. Process characterized in that it consists essentially in gripping the end (3) of the filament and positioning said filament under tension in prolongation of the last wound turn, in producing a slack loop parallel to the end (3) of the tensioned filament, then in forming a twist by twisting a length of the slack loop with the end (3) of the tensioned filament, in then tightening the obtained twist on the bobbin (1) and in cutting the remaining end of the filament. The invention is more particularly applicable in the field of the textile industry, in particular for the winding of filaments and particularly knotting an end of the filament on a bobbin.
