Abstract
A method for fastening a yarn end (2) on a bobbin (1), comprises placing the bobbin (1) horizontally on two spaced supports which support the bobbin along two lines parallel to the axis of the bobbin. A partial vacuum is created in a space located near the bobbin (1), the partial vacuum being sufficient to suck the non-fastened yarn end (2) into that space. The bobbin is caused to rotate in order to wind the non-fastened yarn end (2) on the bobbin. The yarn end (2) is fastened on the bobbin (1). While step (b) is being performed, the bobbin (1) is rotated at the same time in order to unwind the non-fastened yarn end (2) so that this end can engage by suction to a sufficient extent within the space located near the bobbin (1).
