Abstract
In a pivotable suction tube (3) for taking up a yarn from a bobbin, there is provided for transfer of the yarn to an operating element, on its side facing the bobbin, an elongate slot (32), with which is associated a controllable closure piece (33, 35) extending over at least a substantial portion of it. The suction tube (3) possesses a tubular section (30) having a shape being symmetric to its axis with which is associated as a closure piece a rotatable slider (33) provided with an axial slot (330). The closure piece (33, 35) carries a stop (333, 352) with which is associated a counter-stop (20, 410) which becomes effective in dependence on the pivoting motion of the suction tube (3).
